(1) Flocculant: Sometimes called coagulant, it can be used as a means to strengthen solid-liquid separation. It is used in the process of primary sedimentation tank, secondary sedimentation tank, flotation cell and tertiary treatment or advanced treatment.
 
(2) Coagulant: The auxiliary flocculant acts to enhance the coagulation effect.
 
(3) Conditioning agent: also known as dehydrating agent, used for conditioning the excess sludge before dewatering, and the varieties include the above-mentioned partial flocculating agent and coagulant.

(5) Antifoaming agent: mainly used to eliminate a large amount of foam which occurs during aeration or agitation.
