Effluent treatment plant utilizes different technologies and processes for treatment of the waste. They can be streamlined for physiochemical treatment and biological treatment followed by tertiary treatment. Integrated functions with user friendly control makes the operation much easier. Our engineers can also custom design effluent treatment plants based on the specific requirements of the clients. 

Modern wastewater treatment may go to different depths. It can be graded into primary, secondary and tertiary treatment. The degree of treatment is determined by the water quality and whereabouts of the water after treatment.
1. Primary Treatment
The primary treatment mainly removes suspending solid pollutants, and most physical treatment completes and stops at this step. After the primary treatment, BOD can be generally removed by 30%, which falls behind the discharge standards. The primary treatment is a pretreatment for the secondary one.
2. Secondary Treatment
The secondary wastewater treatment removes colloidal and dissolved organic pollutants (BOD, COD substances) in the waste water, with a removal rate of up to 90%, so as to meet discharge standards for organic pollutants. The suspended solid removal rate reaches 95%, and the discharged water is much cleaner.
3. Tertiary Treatment
The tertiary treatment performs further processing on hardly degradable organics, nitrogen and phosphorus-soluble inorganic substances that can lead to eutrophication of water. The main methods are nitrogen and phosphorus removal, coagulation sedimentation, sand filtration, activated carbon adsorption, ion exchange and electrodialysis.
