What Are The Ways In Which Coal-based Activated Carbon Can Be Used To Treat Drinking Water?

Coal-based activated carbon is used in the purification of toxic gases, waste gas treatment, purification of industrial and domestic water, and solvent recovery. And it is widely used in all aspects of industrial and agricultural production. When coal-based activated carbon is used for advanced treatment of drinking water, there are usually the following ways: wholesale granular activated carbon

1. Activated carbon-sand filter material double-layer filter material filter, that is, coal-based activated carbon is used to replace part of the sand filter material in the original sand filter. Carbon-sand double-layer filter media filter. The adsorption of the carbon layer and the filtering effect of the sand layer can effectively remove organic pollutants in the water. It can also remove ammonia (when NH4 <2mg / I).

2. Replace all sand filter materials in the sand filter with coal-based activated carbon to play the role of adsorption and filtration.

3. Separate activated carbon pool after quick filter. That is, a GAC filter is set behind the sand filter for secondary filtering. The sand filter mainly removes alum flowers. The activated carbon pool absorbs organics, phenols and odor. Compared with the above two processes, the infrastructure cost of a separate activated carbon pool is higher. However, it can use more activated carbon adsorption, reduce operating costs, easily replace activated carbon, and can more effectively remove TOC, volatile organic compounds and special organic compounds.

4. Biological activated carbon (BAC) process refers to the activated carbon adsorption process of ozone-pretreated water. The ozone biological activated carbon water purification process (BAC method) combining ozone with granular activated carbon includes three processes: ozone oxidation, activated carbon adsorption, and biodegradation. https://www.coconutactivatedcarbon.comThe BAC method can efficiently remove organic matter in water and prolong the service life of activated carbon.
