CSWE Series Ship Sewage Treatment Equipment
The CSWE series ship sewage treatment equipment consists of three watertight tanks: two-stage biological oxidation chamber and MBR chamber.
Sewage flows into the oxidation chamber, where microorganisms in the activated sludge degrade organic matter in the sewage. The sewage then flows by gravity through flow channels into the secondary oxidation chamber, ensuring sufficient retention time for the sewage. After deep degradation, it flows from the top into the sedimentation chamber. The flocs (activated sludge) in this chamber are vacuum-extracted by a blower and returned to the oxidation chamber, maintaining a balanced concentration of activated sludge in each chamber. After sedimentation and purification, the water passes through an internal special filter module, is disinfected by ultraviolet light, and then discharged. If the activated sludge becomes ineffective, the external membrane three-way valve can be manually switched, and an auxiliary ultrafiltration membrane can be used to improve the effluent quality and ensure compliance with standards.
Effluent Quality Standards:
- Chemical Oxygen Demand (COD): < 125 mg/L
- Five-day Biochemical Oxygen Demand (BOD5): < 25 mg/L
- Suspended Solids (SS): < 35 mg/L
- Thermotolerant Coliform Bacteria (M.P.N): < 100/100mL
- pH Value: 6-8.5
- Residual Chlorine: 0.5 mg/L
