The treatment of industrial sewage needs a variety of sewage treatment agents. These agents are used to treat industrial effluents to meet effluent discharge standards. According to different uses, these sewage treatment agents can be divided into the following categories:
Flocculant: flocculant, also known as coagulant, is mainly used for strengthening solid-liquid separation in sewage treatment. Used for primary sedimentation tank, secondary sedimentation tank, flotation tank, tertiary treatment or advanced treatment and other processes.
Coagulant aid: Coagulant aid is generally used with flocculant to enhance the flocculant flocculation effect.
Demulsifier: Demulsifier is mainly used for the pretreatment of oily sewage containing emulsified oil before air flotation. The variety includes the flocculant and coagulant aid mentioned above.
Defoamer: Defoamer is mainly used to remove foam during aeration or stirring.
PH regulator: Used to adjust acidic or alkaline wastewater to neutral wastewater to promote flocculant action.
REDOX agent: used for sewage treatment containing REDOX substances.
Disinfectant: used to disinfect the water after sewage treatment.
Polymersco reminds you that many wastewater treatment agents are used in industrial wastewater, but none are used only under a single condition. One agent works differently in different situations and in different sewage.
