VOC water treatment equipment

K-FILTER®

We have developed a water purification system that can perform advanced treatment up to the level of water for food factories.

We provide water purification equipment that can be used in food factories by removing trace amounts of harmful organic substances such as 1,4-dioxane from groundwater and well water using K-FILTER®.It can purify safe, high-quality water without producing by-products, and because the system allows K-FILTER® to be used repeatedly, it can purify water at low cost.

Features

By incorporating activated carbon fiber K-FILTER®, which has a high VOC removal rate, and adopting an on-site adsorption/desorption method, we have put into practical use a new, unprecedented water treatment system. VOC removal is possible at a high removal rate and low cost, contributing to compliance with regulations, reducing wastewater treatment costs, and water reuse.

High-efficiency treatment VOC in water and recovery of valuable resources: K-FILTER® has high adsorption and desorption properties, so it is highly efficient and stably removes VOCs from water. In addition, desorbing by water vapor, the volume of wastewater can be reduced and VOCs in wastewater can be recovered as valuable resources.

Selective VOC removal and space-saving design: Efficiently removes specific VOCs (e.g. 1,4-dioxane). On-site regeneration of the adsorbent requires only 1/500 to 1/1000 of the amount of activated carbon compared to the conventional adsorption type activated carbon tank, and the installation area is also small.

No routine maintenance required: No waste, such as excess sludge, is discharged, so routine maintenance in not required.
In addition, the system can recovers from standstill to operation in a short time, so it can be operated when necessary.
