★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.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

Are you struggling to explain "safety" to the client using just drawings? - The risks in blind spots are difficult to convey to the client through drawings alone. - Safety measures often become a target for cost reduction, making it hard to communicate their necessity. - There is a concern that the client might say, "It's more dangerous than I thought," after completion. Risks that are visible to design professionals are not easily understood intuitively by clients who are outside the field. This document is not just a simple explanation of sensor functions; it is a guide to visually explain "why sensors are necessary in that location." It can be used directly as explanatory material for the client. Here are three key points for utilizing this document: 1. Visualization of Risks Blind spots during vehicle departure and contact risks within the site are illustrated clearly. 2. Clarification of Selection Criteria A comparison table outlines the differences between complex sensor types such as infrared, ultrasonic, and loop coils. 3. Diagram of System Configuration It illustrates not just the sensors alone, but how they combine with components like rotating lights and control panels, providing practical assistance for electrical equipment design. Please make use of this to prevent "rework after completion" and "accident risks."
