The odor problem in the foundry was immediately resolved with a deodorizer. The image of the tank shows the condition of the waste collection area about three days after starting operation, and customers who saw this were amazed, saying, "Can this much be captured?!"

• Ventilation and Exhaust
• Gas recovery/treatment equipment

There was a request to efficiently deodorize the dust and odors that scatter during the nanofiber manufacturing process, leading to the introduction of the dust collection and exhaust gas deodorization device, Deolizer. With the treatment by Deolizer, the dust collection efficiency was enhanced, and the exhaust gas absorption efficiency was also improved.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

In the process of crushing and burning the mycelium substrate, dust, resin, and tar were scattered, leading to complaints from nearby farmers; however, by efficiently capturing these substances, complaints from farmers have become nonexistent.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

There was a challenge in the manufacturing process regarding whether it was possible to deodorize the odors of MEK (methyl ethyl ketone), rubber, and organic solvents (such as toluene and xylene). In some cases, there were concerns that secondary treatment might also be necessary, but the complaints from the neighbors were resolved with just the primary treatment.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

Phenol and resin tar are reliably captured by the deodorizer, allowing only substances that are insoluble in water, such as styrene, to be processed in the combustion unit, thereby solving the odor problem.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

The exhaust gases emitted from the painting drying furnace are being initially treated through combustion methods, but they were not being fully processed, leading to complaints from nearby residents. Additionally, gas leaking from the drying furnace was lingering in the facility, worsening the working environment; however, the complaints from the neighbors have ceased, and it has become possible to treat the leaking gas that was accumulating above the factory, resolving the issue.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

It became almost odorless shortly after installation, and not only did complaints from neighbors disappear, but the working environment also improved. The low running costs and minimal maintenance were appreciated.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

Considering the improvement of dust collection efficiency and the reduction of cleaning efforts, there was a challenge regarding how much dust could be collected and how much casting odor could be reduced. However, with the processing of Dust Fall + Deodorizer, the dust collection efficiency was enhanced, and the exhaust gas absorption efficiency was also improved.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

There was a challenge to reliably capture odor substances such as ammonia containing resin, aiming to improve the working environment and prevent pollution. After the installation of the scrubber deodorizer, the working environment was significantly improved, and the diffusion of odors to the surrounding area was sufficiently suppressed, leading to additional orders for scrubber deodorizers even for the existing casting line. Customers have commented that the odor removal is "almost too effective," but since most of the removed substances are inorganic soot, it is undeniable that there will be work involved in removing them. We have established a maintenance system in Thailand to address this.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

Since it is emitted along with hazardous exhaust gases such as carbon disulfide and hydrogen sulfide, which do not dissolve in water, caution is required due to risks of corrosion and explosion. As a result of installing the deodorizer, it was possible to reduce formaldehyde levels from several tens of ppm to a single digit.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

Initially, activated carbon and other methods were planned for secondary treatment, but water-soluble organic solvents like PGMEA are captured at around 80% efficiency with just the scrubber deodorizer, and it is still operating while maintaining that performance.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

It has been confirmed that water-soluble organic solvents such as PGMEA and acetone can be captured without any issues, and it has been found that a single layer of water film is sufficient for treatment, rather than requiring two layers.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

In establishing the new factory, we were considering the introduction of deodorizing machines, but since the highly effective combustion-type deodorization systems are very costly, we were exploring alternatives. At that time, we learned that T Company in Hiroshima Prefecture had successfully handled exhaust gas treatment for their painting drying furnace, and they introduced us to your company. Since it was a recommendation from a reputable customer with proven results, we had a high level of trust and proceeded with the delivery of the water film scrubber (exhaust gas treatment device) "Deo-Riser" without a demonstration experiment. As the delivery was timed with the new construction, we were able to efficiently design the installation locations for the shower booth and circulating water treatment tank, as well as the ducts and piping connecting them, while significantly reducing the installation costs at the same time.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

During the cleaning of manufactured products with organic solvents, solvent odors were being emitted and flowing into the offices in a separate building, necessitating the effective capture of water-soluble organic solvents. By using one Deodorizer DR-30W to perform water film cleaning with an airflow of up to 450㎥/min, we successfully reduced the odor concentration, which exceeded 1000, to below 400 at all times. The effectiveness of the delivered dust collection and exhaust gas deodorization device, the Deodorizer, was recognized despite the difficulty in capturing VOC gases, leading to a repeat order. The previous issue involved a large outbreak of specific microorganisms in the groundwater that caused the screens to become clogged; however, this phenomenon was resolved by administering chlorine in a drip method and managing it at low concentrations.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

The exhaust gases from the painting drying furnace contain substances such as formaldehyde, resin, and tar, which led to persistent complaints from neighbors due to the irritating odors. Additionally, the factory had limited space for installing deodorizing equipment, making it seem difficult to implement. However, the scrubber deodorizer has a compact design that can be installed in tight spaces, leading to its adoption. Regarding the circulating water in the deodorizer, three months before the COD and BOD values reverse is considered the appropriate time for replacement. After primary treatment with the deodorizer, the concentration was reduced to 2 ppm, improving to a level that allows for exhaust without the need for a secondary treatment system, completely eliminating complaints from neighbors. Furthermore, the water that captures odor components in the shower becomes formalin, but aeration by the Aqua Blaster promotes aerobic decomposition, allowing it to be reused as circulating water. Additionally, since resin and tar substances are also decomposed, there is no adhesion to the pit walls, helping to reduce running costs, which has been very well received.

There was a challenge in reliably capturing rubber debris and finely shredded wire. Rubber debris and wire are now reliably captured, and there have been no occurrences of duct fires in the downstream section. Compared to the previously used wet-type dust collection and exhaust gas treatment system, (1) the capture efficiency has significantly improved. (2) There is no longer any concern about duct fires in the downstream section. (3) The screens are less likely to become clogged. Based on this evaluation, we have decided to deliver a total of five units.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

There was concern that the exhaust odor from the painting drying furnace at the new factory might negatively affect the neighboring area. The exhaust was treated with one unit of deodorizer DR-4W using a water film cleaning method. Since the startup until now, there have been no issues with odor at all.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

At the charcoal-grilled chicken factory, the exhaust gases during production were causing pollution in the neighborhood, and there were no effective measures for deodorization. One unit of the deodorizer DR-30W (FRP specification) was used along with a deodorant spray chamber for cleaning. Although the odor was considerable, it was possible to eliminate complaints from the neighbors entirely.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

When drying sludge generated from community wastewater treatment facilities in a drum to produce compost pellets, mainly ammonia-based exhaust gases are emitted. It is cleaned using one unit of the deodorizer DR-2W (made of PVC) and a dilute sulfuric acid drip system. While maintaining a pH close to neutral, it maintains performance with ammonia gas concentration reduced from 100 ppm to below 1 ppm.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

Due to the request to prevent the strong odor containing chemical smells generated by the newly established casting line, we implemented a water film cleaning system with a deodorizer DR-16W, achieving an exhaust gas flow rate of 0.73 m/sec. The working environment has been significantly improved, and the diffusion of odors to the surrounding area has been sufficiently suppressed.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

During the vulcanization process of rubber product manufacturing, exhaust gas mixed with dust and organic solvents was generated, leading to complaints from nearby residents. There were concerns that secondary treatment might be necessary, but the complaints from the neighbors were resolved with just primary treatment.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

During the manufacturing of rubber products, exhaust gases containing siloxanes and silicones are generated. There is a desire to capture these gases inexpensively and to deodorize them, so a deodorizer has been introduced. Approximately 80% of the siloxanes could be captured, but as expected, hydrophobic silicone gases escape, so a chamber combining various filters for secondary treatment is planned to be installed.

• Ventilation and Exhaust
• Gas recovery/treatment equipment

In order to establish a new recycling plant for leftover food, there was a desire to prevent odor issues, so a deodorizer was introduced. As a result, the goal of deodorizing to a level that does not inconvenience the neighboring factory was achieved, and the smell of leftover food is effectively captured, allowing the plant to operate without any problems.

In 2008, a wastewater treatment system was delivered to a bus depot (commonly known as a maintenance and washing facility). Before the installation, a large amount of oil sludge was generated, but by installing aeration pipes, Aqua Blaster, in the existing water tank and performing aeration, we successfully reduced the generation to one-sixth. Since the oil sludge was being treated as industrial waste through incineration, this indirectly cut CO2 emissions by one-sixth as well. Although the electricity consumption and maintenance costs for the aeration pipes, Aqua Blaster, increased, the costs for sludge recovery (cleaning costs) were significantly reduced, resulting in an annual cost reduction of 2.2 million yen.

Since it is not a designated facility, we had not installed wastewater treatment equipment until now. However, we received complaints from nearby residents about the foul odor from the wastewater, so we were consulted about implementing measures as cost-effectively as possible. Traditionally, we would have installed a buried type of blaster tank underground, but instead, we set it up above ground to reduce the initial costs of the wastewater treatment system. As a result, the foul odor completely disappeared, and the complaints from the neighbors subsided, leading to expressions of joy from the factory manager in charge.

In 2001, we conducted treatment of a mixture of mineral oil degreasing cleaning water from machine parts and kitchen wastewater using a unit tank equipped with an aeration pipe Aqua Blaster. Although the inflow volume is small, the wastewater has a high concentration of mineral-based normal hexane extractives, which initially raised concerns. However, since the installation, we have operated without exceeding the treatment standards even once. As a result of successfully treating the wastewater at the facility, we received a repeat order for the wastewater treatment from the headquarters employee cafeteria.

In February 2008, we delivered a wastewater treatment system with a capacity of 30m³ per day to a bread-making factory. With the aeration from the aerator Aqua Blaster, we were able to maintain a dissolved oxygen concentration of over 5.0 mg/L even in summer, and through collaboration with decomposing microorganisms, we successfully reduced high concentrations of oil and fat, which were at 500 mg/L, to a single digit within 40 hours of retention. Raw wheat flour, also known as β-starch, also flowed in large quantities, but until now, the treated water has never exceeded the contracted values.

In 2001, we delivered the Aqua Blaster wastewater treatment system with aeration pipes to a school lunch factory that produces 12,000 meals daily and discharges 220 to 250 m³ of wastewater per day. Initially, there were issues such as foaming, but even after nearly 10 years, it has been operating without any problems.

Despite reducing the 400t water tank to 200t and switching from river discharge to sewage discharge, we successfully achieved an annual cost reduction of 15 million yen. Additionally, while 2.5 workers were previously required, after installation, only the removal of screened sludge was necessary. Furthermore, since the BOD and SS regulatory values in this area were below 600 mg/L, there were times when treatment was excessive, allowing us to stop the nighttime blower. As a result, we received the evaluation that it was "a dream-like wastewater treatment system," and the wastewater treatment equipment for the new factory was awarded a special order for the "Iens Innovative System."

Since it was a parallel two-system processing, to confirm the performance of the Aqua Blaster, all the biological carriers from one of the towers were removed, and the Aqua Blaster was installed with the same air volume. Upon checking the processing efficiency, the load reduction rate for the conventional carrier processing was 24.2%, while the tank with the Aqua Blaster achieved a reduction rate of 39.1%. As a result, the overall load changed from 2,960 mg/L to 2,380 mg/L, resulting in a "1.24 times capacity difference." Even without the supported carriers, the performance was demonstrated, and it was naturally installed in the remaining tower, leading to the decision to remove carriers in other factories as well and implement the Aqua Blaster.

High concentrations of hydrogen sulfide were generated from the wastewater treatment facility of a renowned hotel, established by a major general contractor, exceeding the discharge standards. However, by installing a prototype of the Aqua Blaster, the hydrogen sulfide levels were reduced to 0.0 ppm, successfully clearing the discharge standards without using a pressurized flotation device. This led to a ripple effect in other top-tier hotels, and with funding from Hyogo Prefecture, it became the foundation of the current technology of Iens, as a "wastewater treatment facility without sludge treatment" (processing SS below discharge standards).

Before the installation of the Aqua Blaster, a large amount of oil and grease scum accumulated in just one day, leading to the formation of oil balls. Hydrogen sulfide was generated to the extent that it corroded surrounding equipment. The oil balls on the water surface and those that sank to the bottom were regularly manually retrieved and disposed of as industrial waste. As a result of installing the Aqua Blaster, the BOD removal rate improved significantly to 80%, and the removal rate of n-hexane extractable substances improved to 82%. Even after more than eight and a half years, there has been no need for removal or dredging work, and a no-maintenance state has continued. The dramatic improvement in water quality has led to waterfowl visiting the sedimentation tank every year without fail. Below are the results from the installation in 2012 to 2020 over eight years: - With a 6-hour retention time in the adjustment tank, BOD and n-hex were cut by over 80%. - The floating oil and grease and settled sludge that had been generated in the adjustment tank have not been removed even once in eight years. - Hydrogen sulfide levels decreased from 100 ppm to 0 ppm. - At the outlet of aeration tank 1, the Setouchi regulations are being met. - The sludge conversion rate for BOD was reduced from 35% to 25%. - The sedimentation tank has remained stable, attracting ducks. - Excess sludge has drastically decreased, and the odor from its steam drying is no longer a concern.

In this factory, aeration was being performed using a stirrer, but due to a lack of dissolved oxygen (DO), aeration was also being conducted simultaneously with a disc-type diffuser. However, due to ongoing treatment failures, the existing blower was utilized to change the aeration device to the Aqua Blaster AL-750, which allowed for successful treatment, leading to the complete shutdown of the 55W stirrer to this day. Subsequently, the amount of sludge generated per unit of production was reduced, resulting in repeat orders for other wastewater series tanks. ★ Sludge reduction rate per unit of production → 18.8% reduction ★ Conventional stirring device 55Kw → Completely stopped

To prevent foul odors and enhance processing capacity in the adjustment tank, the existing aeration device was replaced with an Aqua Blaster, resulting in a reduction of BOD by over 30% based on the weighted average. Additionally, previously, chemical dosing was performed due to poor sedimentation in the final settling tank, but since the sedimentation issues have been resolved, stable discharge can now be achieved without chemical dosing. Notably, customers are very satisfied that even during increased production or incidents of sudden inflow of high-concentration wastewater, the system can handle it without any issues. This has led to the special adoption of pre-treatment in related factories.

To address neighborhood concerns, 63 units of the Aqua Blaster AS-250 were installed to remove unpleasant odors such as hydrogen sulfide generated from the adjustment tank. After installation, when sludge was returned from the sedimentation tank to the adjustment tank, surplus sludge (approximately 5.1 tons/month) ceased to occur, and electricity costs were reduced by about 10%. The person in charge mentioned, "The fact that we no longer need to manage the dewatering machine has greatly helped us, as the measurement work now only takes about 2 hours a day, reducing the work time to one-sixth." The BOD cut rate in the adjustment tank is an average of 38.9% during high-load wastewater inflow and 61.4% during normal times, which has reduced the load on the subsequent aeration tank.

As shown in the table above, the pH automatically rises without the use of neutralizing agents, and the adjustment tank alone has cut the load by over 70%. Of course, it has also eliminated any foul odors. Later, a load more than three times higher flowed in, yet the adjustment tank alone managed to cut BOD by 50% and normal hexane extractable substances by 60%. The person in charge later emailed me, saying, "The concentration of raw water flowing in is far higher than the values we had heard, and it is remarkable that we are able to handle this load."

Due to the occurrence of processing issues, we decided to abandon the existing sprinkler bed and removed it, installing the Aqua Blaster AL-750 in the aeration tank. Until now, we had no choice but to use coagulants after passing through the sprinkler bed, but after the installation of the Aqua Blaster, we no longer needed coagulants even after removing the sprinkler bed. Additionally, since the treatment became very stable, we successfully included the high-concentration yogurt wastewater, which had previously been disposed of, in the effluent treatment, leading to a reduction in industrial waste costs. The recent analysis of the discharged water showed BOD at 9.4 mg/L, n-Hex was not detected, and other parameters also met the river discharge standards without any issues.

To enhance the processing capacity of the oil and fat content, the existing aeration device in the adjustment tank was changed to an Aqua Blaster, resulting in an increase in processing capacity. As a result, the amount of normal hexane extractables was reduced by over 50% after passing through the adjustment tank, and other items similarly decreased, leading to a halving of the sludge generated during pressurized flotation. Previously, the pH on the inflow side tended to be acidic, requiring chemical neutralization; however, now, due to the effect of the Aqua Blaster, it has automatically become neutral, eliminating the need for neutralizing agents. Additionally, the dissolved oxygen (DO) level at the outlet of the adjustment tank has consistently been maintained at over 2.0 mg/L, resolving issues with sedimentation in the final settling tank, and the odor of dewatered sludge has changed from anaerobic to aerobic.

Due to the increase in wastewater volume associated with the factory expansion, the aeration device of the existing treatment tank was changed to an Aqua Blaster to enhance processing capacity. By installing Aqua Blasters in the adjustment tank and aeration tank, we successfully accepted a load increase of 10-20% without increasing the tank size. Furthermore, it has become possible to carry out treatment without using a pressurized flotation device.

The work to eliminate the foul odor from the adjustment tank and the recovery of floating oils has been completed, and the Aqua Blaster AS-250 has been installed to improve processing capacity. As a result, although hydrogen sulfide had been accumulating and causing processing issues, the foul odor has disappeared, and the wastewater is no longer acidic, leading to a significant reduction in the amount of chemicals used. Furthermore, the manual collection of floating oils, which had been done three times a week, has ceased, along with the generation of 36 tons of floating sludge. Additionally, the final sludge from the subsequent activated sludge treatment has been reduced from 200 tons to 170 tons, representing a 15% reduction in volume.

A new Aiens Innovative System (AIS) has been established at a cut vegetable factory with a daily drainage capacity of 300m³. The processing flow consists of an adjustment tank ⇒ 7 AIS tanks ⇒ a sedimentation tank ⇒ river discharge. By returning the sludge from the sedimentation tank to the adjustment tank, the amount of sludge generated is minimized, and despite inflows exceeding the designed load, the water quality analysis results show that all parameters meet the standard values. In a separate factory, issues related to odors have arisen, and the introduction of AIS is also being considered there. This is the first case that has proven the ability to discharge into rivers without using activated sludge.

At a tofu and soy milk factory in Shizuoka Prefecture, simply changing the aeration device in the first aeration tank from a membrane type to an Aqua Blaster resulted in a 39% reduction in sludge, leading to the shutdown of one blower. As a result, at this factory in Tokushima, the aeration devices in all water tanks, from the adjustment tank to the aeration tanks, were changed to Aqua Blasters. Completed at the end of July, despite several days exceeding 35°C, the system remained stable and was able to maintain the sedimentation tank in the condition shown in the photo. At this site, they also succeeded in reducing the inverter frequency of the auxiliary blower to 25Hz. It is planned that this blower will eventually be shut down as well.
