WCH series of crushing disinfecting sewage storage cabinets used for storage of raw sewage or solid residue processed by sewage treatment plant for various types of vessels. Also work with the sewage treatment to form a complete set for forwarding counter use. This device has the features of dosing disinfection, residue crushing, cabinets washing and discharging the treated sewage residue to the outboard row. The storage cabinet structure is simple and easy to operate and the quality of water which is processed in line with the requirements of IMO shredders and collection tank. Main technical performance: Water quality of emission: 1. coliform group≤1000/100ml, and there is no visible suspended solids. 2. Maximum equipped with power WCH-0.34 1.5kw 380V/50Hz WCH-520 3kw 380V/50Hz Principle: Raw sewage or solid residues treated by sewage treatment plant get into the sterilized manure storage cabinet, accumulating to a certain level in it, then to start the smashing pump. To make sewage or solid residue runs the repeated cycle of crushing, adding to drugs to it for disinfection at the same time. When sewage or solid residue crushed to a certain degree, we can send the waste water to the shore reception facilities through the international emission joint on the deck, or discharge directly to the outboard in the non-controlled sea area.
