★Why not turn the waste liquid you are currently disposing of into something valuable?★ Accepting tests for 10 kg of solid material from 1000 L of slurry liquid in 1 hour.

The "Pleated Filter Dewatering" device allows for the suction filtration of high-concentration slurry (mud-like mixture), forming a cake layer on the filter surface. This formed cake layer is then dewatered and dried, allowing it to be collected as sludge (aggregated solid). Our unique pleated filter enables dewatering and drying in a compact device with a short cycle time. No coagulants or filtration aids are required. The moisture content of the sludge can be as low as 1% for inorganic materials. 【Features】 ■ Individual liquid separation to dewatering and drying in 60 minutes (all-in-one) ■ Compatible with ultra-high concentration turbid water ■ Processing capacity of 400 kg/day (based on processing 1,000 L of 20,000 PPM turbid water) ■ Maintenance requires only filter replacement ◎ For more details, please refer to the PDF document or feel free to contact us.

It decomposes harmful chemicals, bacteria, and organic matter through radicals (free radicals) generated during ozone and bubble disappearance!

Even wastewater that appears colored and does not have sediment can be treated with ozone microbubbles, resulting in the removal of odors, disinfection, and achieving clarity comparable to tap water. The oxidation power of ozone is second only to fluorine and has about 6 to 7 times the disinfection capability compared to chlorine, along with various beneficial effects such as deodorization, bleaching, inactivation of algae, pesticide decomposition, and removal of organic matter. 【Features】 ■ Compact and inexpensive ■ Cost reduction ■ Ozone can remain for a long time ■ Efficient use of ozone ■ 3.83 million bubbles per cc ◎ For more details, please refer to the PDF document or feel free to contact us.

We will introduce examples of reducing industrial waste costs and converting residual materials into feed to contribute to the creation of valuable resources.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a food processing factory to dry and reduce the weight of their residual materials in order to cut disposal costs. 【Case Study】 ■Industry: Food Processing Factory ■Challenges - When disposing of residual materials (press cake), the disposal fee is determined by weight, leading to high costs for disposing of moisture-laden residuals. - They wanted to dry and reduce the weight of the residual materials to cut disposal costs. To further enhance the efficiency of processing the juice generated during the drying process, we proposed a combination of dewatering and ECO Clean. This not only reduced industrial waste costs but also contributed to converting the dried residuals into animal feed, generating valuable by-products. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce an example of consolidating into a single machine, achieving a reduction in installation costs and running costs!

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a metal processing factory to efficiently recover rare metals from high-concentration rare metal-containing water (valuable material) without lowering the concentration. [Case Study] ■Industry: Metal Processing Factory ■Challenges - Previously, recovery involved four processes (solid-liquid separation, concentration, dewatering, drying), which incurred significant time and costs. - There was a desire to efficiently recover only rare metals from high-concentration rare metal-containing water (valuable material) without lowering the concentration. Our company has consolidated the process into a single machine for de-drying. This one unit handles all roles, significantly reducing installation costs, installation space, and running costs (electricity and maintenance expenses). *For more details, please refer to the PDF document or feel free to contact us.

90% OFF on water utility fees! Here are examples of reducing maintenance frequency and lowering disposal costs.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a resin factory to reduce maintenance costs caused by impurities entering the heat exchanger from the cooling water used during cutting. 【Case Study】 ■Industry: Resin Factory ■Challenges - The large amount of cooling water used to cool the water during cutting contains impurities (resin scraps) that are entering the heat exchanger. - Maintenance costs for the heat exchanger are high, and we want to reduce them. We proposed dehydration to remove impurities from the cooling water. By using the cleaned cooling water in the heat exchanger, we reduced the maintenance frequency from four times a year to once a year. Additionally, we not only removed impurities but also reduced their volume to lower disposal costs. *For more details, please refer to the PDF document or feel free to contact us.

50% reduction in water utility fees! Here is an example of how colored groundwater has been purified for use.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a hot spring facility to purify colored groundwater containing organic matter so that it can be used, in order to reduce water utility costs. [Case Study] ■ Industry: Hot Spring Facility ■ Challenge: Reduction of water utility costs Purification of colored groundwater containing organic matter for use Our company proposed a system that combines coagulation sedimentation tanks, ECO Clean, and ozone microbubbles to achieve purification, decolorization, deodorization, and sterilization, resulting in water utility costs being halved. This generated a cost benefit of approximately 50 million yen annually, equivalent to 150,000 liters per day, or 750 baths for household use. *For more details, please refer to the PDF document or feel free to contact us.

Achieving one-tenth of water supply fees! Here are examples of using purified river water for cleaning purposes.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a precision parts/plating factory that wanted to reduce costs by purifying river water for use as cleaning water for precision electronic components. [Case Study] ■ Industry: Precision parts/plating factory ■ Challenge: The factory has been using tap water for cleaning precision electronic components, but the water bills are high. They want to reduce costs by purifying river water for use as cleaning water. Our company purified the turbidity of river water to the level of tap water using "ECO Clean." By enabling the use of river water, we provided water at one-tenth the price of tap water, achieving a 90% reduction in tap water costs through purification and utilization. *For more details, please refer to the PDF document or feel free to contact us.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.

[To the owners of parking lots and parking lot construction companies] "I’m worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask that customers arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
