日本原料 List of Products and Services

We have developed a filtration device called "Chiffon Tank" that allows for consistently stable filtered water quality without the need to replace the filtration media. The filtration media within this product is always kept in a clean state, so only a small amount of supplementary sand is required, and there is no need to replace the filtration media at all. By completely detaching the hard, adhered turbidity through chiffon cleaning and performing backwashing solely for the purpose of rinsing that turbidity, it is possible to significantly reduce the amount of backwash water compared to conventional filtration devices. 【Features】 ■ Dramatically reduced maintenance costs ■ Contributes to zero emissions ■ Significantly lowers water quality maintenance costs ■ Supports wastewater treatment ■ The chiffon screw part is cartridge-type, making maintenance of the tank itself easy *For more details, please refer to the PDF document or feel free to contact us.

The "0.6 Interceptor" is a filtration material developed to significantly improve the amount of suspended solids captured and the backwash efficiency in rapid filtration ponds. It manufactures filtration sand based on a new concept that captures suspended solids in three dimensions (layers) rather than just on the surface. Without modifying existing equipment, it allows for a maximum of twice the treatment capacity simply by replacing the filtration material, and it also contributes to reducing the electricity consumption of filtration pumps, backwash pumps, and more due to the increased amount of suspended solids captured. 【Features】 ■ Reduced frequency of backwash and extended filtration duration ■ Significant reduction in backwash water ■ Downsizing of wastewater treatment facilities ■ Improved filtration efficiency (reduction in operation and maintenance costs) ■ Stable quality of filtered water *For more details, please refer to the PDF document or feel free to contact us.

The "Zebra Layer" is a dedicated filtration material for our water treatment devices, the chiffon tank and mobile chiffon tank. Currently, the multi-layer filtration shows a clean stratification of the layers after backwashing, with turbidity being captured only at two points: the anthracite surface layer and the boundary between the anthracite and the filtration sand. The intermediate anthracite layer hardly functions at all. To activate the anthracite and increase the turbidity capture amount, we have developed this product, which forms anthracite and filtration sand into zebra-striped layers. 【Features】 ■ Disperses turbidity within the anthracite layer ■ Increases turbidity capture amount ■ Reduces costs of backwash water ■ Improves processing capacity simply by replacing the filtration material *For more details, please refer to the PDF document or feel free to contact us.
