Automatic Backwash Nutshell Actived Carbon Water Filter
Activated carbon filter
Activated carbon filter is used for the removal of color, taste, residual chlorine and organics its main mode of action is adsorption. Activated carbon is an artificial sorbent. Activated carbon has developed pore structure and huge specific surface area, so it has a strong adsorption capacity for the dissolved organics in the water, such as benzene and phenolic compounds, and has better removal efficiency for organic pollutants which are hard to be removed by biological and chemical methods, such as chroma, stench, surfactants, synthetic detergents and dyes, etc. Granular activated carbon is able to remove 85% of Ag A , Cr2 + and Cr04 A 2 in the water Through the activated carbon filter bed, the suspended solid in the water is less than 0.1 mg/L, COD removal rate is generally 40% to 50% and free chlorine is less than 0.1mg/l. It can be used as pretreatment of ion exchange, electrodialysis and reverse osmosis in pure water technology so as to remove organics, colloids and residual chlorine; it can be also used as an advanced treatment mean after the secondary treatment to ensure the quality of reusewater.
