⑵ Coagulation aids: auxiliary flocculants play a role to enhance the coagulation effect.
⑶ Conditioning agent: also known as dehydrating agent, used to condition the remaining sludge before dehydration. Its varieties include the above-mentioned partial flocculants and coagulants.
⑷ Demulsifier: sometimes called destabilizer, mainly used for pre-treatment of oily wastewater containing emulsified oil before air floatation. Its varieties include the above-mentioned partial flocculants and coagulants.
⑸Defoamer: Mainly used to eliminate a large amount of foam during aeration or mixing.
⑹pH adjuster: used to adjust the pH value of acid wastewater and alkaline wastewater to neutral.
