Based on the different uses of pharmaceuticals, can be divided into the following categories:
(1) flocculants: sometimes also known as coagulants, can be used as a means to strengthen the solid-liquid separation of the primary sedimentation tank, the second sedimentation tank, flotation tanks and the tertiary treatment or depth of treatment and other process links.
(2) coagulant: auxiliary flocculant to play a role in strengthening the coagulation effect.
(3)Conditioning agent: also known as dewatering agent, used for the conditioning of the remaining sludge before dewatering, and its varieties include some of the above flocculants and coagulants.
(4) Breaking agent: sometimes also called destabilizer, mainly used for the pretreatment of oil-containing wastewater containing emulsified oil before air flotation, and its varieties include some of the above flocculants and coagulants.
(5) defoamer: mainly used to eliminate a large number of bubbles in the process of aeration or mixing.
(6) pH adjusting agent: it is used to adjust the pH of acidic wastewater and alkaline wastewater to neutral.
(7)Oxidizing and reducing agent: used in the treatment of industrial wastewater containing oxidizing or reducing substances.
(8) Disinfectant: used for disinfection treatment before discharge or reuse after wastewater treatment.
