At a major chemical company, Company A, the aging of equipment and concrete tanks was severe, and deterioration was quite noticeable. Although repairs were made every year, there were concerns within the company about whether they could maintain the current state and how long they could continue operations. Our company proposed a concept that would achieve both the extension of the lifespan and improvement of functionality while utilizing the existing tanks, through meticulous investigation and consideration, allowing for renovation without halting operations. As a result, we were able to extend the lifespan of the equipment through renovation and significantly reduce running costs. **Effects of Renovation** **Extension of Equipment Lifespan** - Conducted seismic reinforcement work to avoid the risk of collapse during a major earthquake. - Significantly reduced investment costs compared to the construction of new tanks. **Significant Reduction in Running Costs** - Reduced electricity consumption by approximately 50%. - Reduced sludge generation by about 70%. - Recovered methane gas from wastewater organic matter, leading to a reduction in overall fuel costs for the factory through energy creation. *For more details, please refer to the PDF document or feel free to contact us.*

Nakata Foods is a food manufacturer in Wakayama Prefecture that specializes in the production and sale of pickled plums, plum wine, and plum processed products. The plum seasoning wastewater generated during the pickling process is an extremely high-concentration wastewater exceeding BOD: 100,000 mg/l, making it difficult to treat with conventional wastewater treatment facilities. To utilize the plum seasoning wastewater as a biomass resource, we introduced our anaerobic wastewater treatment facility, "Bio Impact." Previously treated as industrial waste, the plum seasoning wastewater can now be processed at a lower cost due to the high-efficiency anaerobic wastewater treatment facility. This has significantly reduced the burden on small and medium-sized businesses by allowing for acceptance at a more affordable cost than before. 【Facility Overview】 ■ Facility: Nakata Foods Biogas Power Plant ■ Start of Operation: April 2019 ■ Treatment Capacity: 20 tons/day (dedicated to plum seasoning wastewater generated from our own and local plum processing businesses) ■ Biogas Utilization Equipment: Diesel engine generators (60kW x 6 units) ■ Annual Power Generation: Approximately 2 million kWh ■ Treated Water: Utilizes public sewer system *For more details, please refer to the PDF document or feel free to contact us.

"Aero Impact" is a fluidized bed biological membrane carrier treatment capable of high-load processing, which reduces the installation area compared to the standard activated sludge method. By using the Moving Bed Biofilm Reactor (MBBR) method with a fluidized bed carrier, it achieves compactness, high performance, and easy maintenance. There is no need for sludge concentration management in the aeration tank or interface management in the settling tank. It reduces sludge volume through biological activity without using ozone or chemicals. 【Features】 ■ Achieves compactness, high performance, and easy maintenance ■ Capable of high-load processing ■ Reduces installation area compared to the standard activated sludge method ■ No need for sludge concentration management in the aeration tank or interface management in the settling tank ■ Reduces sludge volume through biological activity without using ozone or chemicals *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case study of our fluidized bed biological membrane treatment system, "Aero Impact." Company C, a chemical company, decided to increase production at Factory H due to strong sales, but faced the challenge of "not having space to enhance wastewater treatment." In response to this request from Company C, we conducted a study centered around our existing aeration tank and the fluidized bed biological membrane treatment system, "Aero Impact." By implementing this product, we can significantly reduce investment costs by utilizing the existing aeration tank and sedimentation tank, and eliminating the need for additional dewatering equipment. [Overview] ■ Industry: Chemical Industry ■ Challenges: Space-saving, labor-saving, cost reduction ■ Implemented Product: Fluidized Bed Biological Membrane Treatment System "Aero Impact" *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce examples of renovations of our "RC Ranger." At a certain steel mill's wastewater treatment facility, the deterioration of the concrete aeration tank was severe, and water leaks from the tank were confirmed. However, there were challenges in constructing a new aeration tank due to site constraints. In response, we carried out repair work on the aeration tank using a temporary aeration tank and a temporary high-speed coagulation and sedimentation device. The high-speed coagulation and sedimentation equipment also enhanced the functionality of the wastewater treatment facility for future repurposing. Based on our experience and achievements as a plant manufacturer, we provide comprehensive proposals ranging from deterioration diagnosis of tanks, repairs, installation and operation of temporary equipment, to renovation suggestions. [Customer Concerns] ■ It is difficult to construct a new aeration tank due to site constraints. ■ Since the factory cannot stop operations, they have given up on a complete repair of the aeration tank. *For more details, please refer to the PDF document or feel free to contact us.

As an example of the renovation services we provide, we would like to introduce a case where we renovated equipment that had been in place for over 40 years, successfully extending its lifespan, enhancing its functionality, and achieving space-saving solutions. After renovating existing equipment that not only suffered from aging but also had seismic issues with the adjustment tank and aeration tank, we succeeded in extending its lifespan to allow for several more decades of continued use. Additionally, we strengthened functionality by introducing anaerobic treatment for high-concentration wastewater, resulting in a 70% reduction in electricity and excess sludge. Furthermore, by removing the old adjustment tank, we were able to effectively utilize the idle land, achieving space-saving as well. We offer various benefits, including the extension of existing equipment's lifespan, improvements in functionality, and space-saving solutions for wastewater treatment facilities. If you are considering renovating existing equipment, please feel free to contact us.
