Customer's demand can be considered in the production.
Coal based granular activated carbon, which raw material is bituminous coal, is made by the production process of crushing, carbonization and activation. This kind of products have the advantages of high hardness, developed pores, large specific surface area, and large micropore's volume. It can be used for removing organic materials and free chlorine in water treatment, and adsorbing harmful gases in the air. It is an excellent adsorbent for drinking water, sewage water, and industrial wastewater treatment.
1) The main characteristics of coal particle activated carbon application are low equipment investment, low price, fast adsorption speed, and strong adaptability to short-term and sudden water pollution.
2) The addition of coal particle activated carbon has obvious effect on the removal of chromaticity. The removal of chroma has been reported to be 70%. Low chroma shows that the removal efficiency of organic matter is high and the effect of removing iron and manganese is good.
3) The addition of coal particle activated carbon has obvious effect on removing smell.
4) Adding coal particle activated carbon can help to remove anionic detergent.
5) Adding coal particle activated carbon can help to remove algae. The addition of coal particle activated carbon can block the light absorption of algae, and it can help to remove algae in coagulation precipitation.
6) The chemical oxygen consumption and the five-day biochemical oxygen demand were greatly reduced by adding coal particle activated carbon. The decrease of these indicators which are positively related to the degree of organic pollution in water indicates the removal degree of toxic and harmful substances in water.
7) The removal of phenol by adding coal particle activated carbon has good effect.
8) The turbidity of effluent was greatly reduced by adding coal particle activated carbon powder, and the water quality of tap water was greatly improved.
9) The effect of adding coal particle activated carbon on water mutagenicity can effectively remove organic pollutants. It is a simple and simple way to improve drinking water quality by conventional technology.
