WCBJ(159) Series Marine Sewage Treatment Plant
Overview: WCBJ(159) series marine sewage treatment unit is a new type one designed according to No.MEPC159 (55) decision by Marine Environment Regulatory Commission of International Maritime Organization. Sewage treated by this unit can comply fully with and meet the discharge standards of all technical indexes in No. MEPC159 (55) decision. This series product has been declared for State Patent for Invention of P.R.China and approved for acceptance, with an approval number 200910209237.X.This series product has passed smoothly the strict type approval test at Changjiang Midstream Water Environment Monitoring Center of Changjiang Water Resources Commission designed by China Classification Society, Wuhan Branch and also obtained recognized certificate, with the Certificate No.WH 1 OT00022.
Main technical parameters:
Suspended Solid(SS): ≤35mg/ L
Escherichia colichin: 100 piece/100ml;
Biochemical oxygen demand(BOD5): ≤25mg/ L;
Chemical oxygen demand( COD): ≤125mg/ L;
PH value: 6.0-8.5
Conditions for use:
This WCBJ(159) series marine sewage treatment unit can be used under the following conditions:
This unit can treat the fecal sewage in any form discharged from ships and sewage discharged from infirmary;
It us used when seawater concentration lower than or equal to 35000mg/ L;
It is used when gradient at any direction lower than or equal to 22.5℃;
It is used under low temperature;
Seawater and freshwater can both be used for unit flush.
Characteristics of unit:
All technical indexes of sewage treated by this unit can meet fully the standards specified in No. MEPC159(55) decision;
This unit can operate automatically;
Sewage treated can achieve the discharge standards due to membrane treatment;
The automatic backflushing function designed on membrane can ensure membrane unblock and extend the membrane service life;
The powerful ultraviolet radiation applied can ensure sterilizing effect;
The automatic cleaning function of ultraviolet radiation can ensure the effective work of sterilization light tube;
Decolorization of water treated by membrane and ultraviolet radiation is well and the water has natural color;
8) This unit can avoid secondary pollution due to no drug for sterilization;
9) High-efficiency oxygenation applied accelerates biological treatment and reduces the size;
10) PLC program control is in favor of high automation leve and easy maintenance.
Specifications and parameters of product:
We also produce the old MEPC standard type- WCBJ Series Marine Sewage Treatment Plant, which is cheaper than the new MEPC standard type.
