Features
K-FILTER ® VOC wastewater treatment apparatus
K-FILTER ® removes trace amounts of hazardous organic substances such as 1,4-dioxane from groundwater and well water, and provides a water purificationequipment that can be used for food production and drinking water. The system can purify water safely and with high quality without generating byproducts,and K-FILTER ® can be used repeatedly, making it possible to purify water at low cost.

●Our unique adsorbent, activated carbon fiber "K-FILTER ®," and on-site recycling system is used.
●Conform with Food Sanitation Law, JWWA leaching test cleared, and can be removed even at concentrations in the order ofppb and ppt.
●Apparatus design proposals are possible even for large water volumes, and no generating byproducts such as formaldehyde.
●Annual consumption is 1/1000 or less compared to granular and powdered coal, and can be combined with oxidative
decomposition equipment, etc.
●Capable of treating 1,4-dioxane, chloroform, trihatomethane, 2-MIB, geosmin, etc.

Features
K-FILTER ® VOC wastewater treatment equipmentBy incorporating K-FILTER ®, an activated carbon fiber with a high VOC removal rate, and adopting an on-site adsorption/desorption system, we havecommercialized a new type of wastewater treatment equipment that has never been used before. VOC wastewater treatment can be performed with ahigh removal rate and low cost, contributing to compliance with laws and regulations, reduction of wastewater treatment costs, and reuse of wastewater.
1 VOC in water can be treated with high efficiency
K-FILTER ® has high adsorption and desorption characteristics, so VOC in water canbe removed with high efficiency and stability.
2 Can concentrate VOC in water>Steam desorption reduces the volume of wastewater and recovers VOC inwastewater as valuable materials.
3 Almost selective removal of specific VOC
Even in the presence of a high concentration of COD, only specific VOC (such as 1,4dioxane) can be removed with high efficiency.
Less activated carbon used for 4 years, less space
Since the adsorbent is regenerated on-site, 500 to 1/1000 of the amount of activatedcarbon is required compared to the conventional adsorbent activated carbon tower,
and the installation area is also space-saving.
5 Easy maintenance and fast recovery time
No waste such as excess sludge is discharged, so daily maintenance is unnecessary.
Recovery time from outages is also fast, so it can be operated only when wastewater
treatment is required.
