Introduction
Active carbon filter is a commonly used water treatment equipment. It can remove residual chlorine that can not be removed in the pre-filtration to ensure service life of following equipment, improve effluent quality, prevent reverse osmosis membrance and ion exchange resin from free residual chlorine poisoning. Meanwhile, it can also reduce COD and SDI value of RO inlet water, to ensure SDI<5 and TOC<2.Oppm.

working principle
Activated carbon adsorption principle is: in the surface of its particles to form a layer of balanced surface concentration. The size of the activated carbon particles also has an effect on the adsorption capacity. In general, the smaller the activated carbon particles, the larger the filtration area. Therefore, the total area of powdered activated carbon is the largest, the adsorption effect is the best, but the powdered activated carbon is easy to flow into the water tank, it is difficult to control, rarely used. Granular activated carbon due to particle formation is not easy to flow, organic matter and other impurities in the activated carbon filter layer is not easy to block, its adsorption capacity, easy to carry replacement.

Applications and features
Food, pharmaceutical, electronics, chemical, industrial wastewater, and other industries.
1. It can meet the requirments of hydraulic system on filter fineness;
2. Filter element should have sufficient strength, or it will be damaged because of pressure;
3. High flow capacity and low pressure loss;
4. Easy to wash and change.
