Aluminum sulfate coagulation wastewater treatment and wastewater treatment with

Aluminum sulfate as the coagulant , it is acidic chemicals, waste water can also be used as an alkaline pH adjustment chemicals . It is a traditional pharmaceutical wastewater , which  organic pigments both participate in the wastewater effluent coagulation treatment , and is also involved in wastewater treatment . We look at what is waste and wastewater coagulation treatment and disposal method .
Wastewater treatment aluminum sulphate coagulation coagulation wastewater treatment to waste water by adding coagulant ( such as aluminum sulfate , ferrous sulfate , etc. ) , dissolved alumina colloid, the colloidal substances in wastewater the fine coagulated or flocculated suspended solids are separated out water and solid contaminants , methods  Flame retardant to purify wastewater .
And wastewater treatment
And wastewater treatment method is the use of treated wastewater and the purification of the approach. The basic principle is to make the acidic wastewater plus the OH or H and the alkaline wastewater OH and H- plus interactions generate weak dissociation of water molecules , while generating additional soluble or insoluble salts, thus  PVC plasticizer eliminate their harmful effects. Obey the law of the reaction equivalent , can be processed using this method and recovered by using an acidic water and alkaline water , acidic or alkaline water can adjust the PH. The chemical treatment of sewage by chemical reaction action to remove the impurities , mainly in sewage processing target inorganic or organic ( difficult biodegradable ) dissolved substances or colloidal substances. Commonly used chemical treatment methods such as chemical coagulation , neutralization, chemical precipitation and oxidation-reduction method . In the coagulation of aluminum sulfate, ferrous applications are more extensive , and in the middle and the most widely applied method is lime , ferrous sulfate is also used for redox .
