Glass Lined Bolted Liquid Storage Tank Used In Wastewater Treatment Process

How to do the wastewater treatment ?

As you know if we discharge wastewater directly , then the earth will be polluted our health is threatened . There is many bacterias and other dangerous materials in the wastewater . Doing the wastewater treatment , many bacterias will be moved , there is no danger to human health or unacceptable damage to the natural environment .

Wastewaster treatment , the first process is doing pretreatment , the purpose is to remove the large solid from the wastewater . The next step is primary treatment , which need clarification and sedimentation tank to finish this process , the purpose is to remove the suspended solid and biochemical particulated from the wastewater .

After finished the pretreatment and primary treatment , it need to do the secondary treatment . For the secondary treatment , it require anerobic mircroorganisms facilities ( most of the wastewater treatment use this facility to do the wastewater treatment ) to do it. The purpose of it is to remove the remaining suspended solid and BOD . Wastewater treatment facilities utilize anaerobic digester ( Glass fused to steel anaerobic digester tank ) to break down sewage sludge and eliminate pathogens in wastewater .

Compartion of kinds of tanks

Center Quality Control
