Why we use activated carbon filter

Granular activated carbon is a new kind of activated carbon, a common used to remove the organic matter in the water and residual disinfectant, protect ion exchange resins such as reverse osmosis membrane water treatment unit, or the destruction of organic dirt from oxidation, activated carbon filter whose water due to its versatility and didn't have any harmful effects, is a kind of popular water treatment products. With the increase of molecular weight, the adsorption efficiency of activated carbon, activated carbon molecules soluble in water because it is over, but the pore structure of carbon should be large enough, to allow the molecule in which the migration, a mixture of high molecular weight and low molecular weight molecules should be designed to remove more difficult species. Most of the organic compound insoluble in water, are more likely to be under low pH adsorption, and with the increase of pH value, the removal rate is reduced, according to experience, in neutral, 7. 0) Above, an additional pH unit, carbon bed size is increased by 20%. Pollutant concentration is higher, the greater the removal capacity of activated carbon, the easier pollutant molecules diffusion and adsorption in the pore, with the increase of wastewater concentration, leakage also will increase, the pollutant concentration is higher, the contact may need more time, active carbon and water hardness is increased, is beneficial to remove organic matter, so whenever possible, will be installed upstream of activated carbon plant ion removal device.
