★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.

In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

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.
