Truong Phuc Surimi processing wastewater treatment system

Centrifugal to recover residue:  Separation of solid phases from liquid phase when the solid phase concentration is large by centrifugal force.

Collection:  Collect all wastewater on the channel leading to the treatment system.

Pressure flotation tank:  Separation of grease mixed in wastewater in two forms of “suspension and suspended sediment” by the DAF pneumatic method to float suspended particles to create surface grease. Surface degreasing by degreaser reduces the contaminant concentration eligible for the biological treatment stage.

Equalization tank: Stabilize flow, contaminant concentration, pH. Preliminary ventilation to avoid anaerobic decomposition causing odors.

UASB tank:  Using anaerobic degrading microorganisms and substrates to create adhesion for microorganisms to work better, ensuring input parameters for the cluster of aerobic biological treatment tanks on the side. after working efficiently and the output water quality is satisfactory.

Anoxic tank + MBBR + Aerobic:

– Alternate use of anaerobic and aerobic processes (slurry circulation) in the system, this allows the best treatment of Nitrogen and Phosphorus in the wastewater.

– The pollutant treatment efficiency is high (98%) and stable, the treatment efficiency does not change when the pollutant load (COD) increases by 20% and the flow changes by 10-15%; Ability to reduce Nitrogen and Phosphorus up to 95% when operating according to specifications; The treated water is supplied through the settling tank.

– The biological treatment process combined with MBBR media is a big step forward in wastewater technology. Metabolism and nitrification take place quickly thanks to the large concentration of microorganisms in the mobile substrate.

Sedimentation tank:  Separation of activated sludge, collecting clear water after biological treatment. The amount of sludge generated is partly circulated to Aerobic, excess sludge is brought to the sludge compaction tank.

Disinfection tank:   In contact with Chlorine to completely destroy Coliforms and other pathogenic bacteria, the treated water meets environmental standards and is discharged into the receiving source.
