Principle Description
The raw sewage or the solid sludge disposed by the treatment plant enters the holding tank through the sewage pump. When the sewage reaches a certain level, the crushing pump is started to cut the sludge, and disinfectant is added for disinfection. When the sewage or solid sludge accumulates to a certain extent, the treated sewage can be sent to the shore receiving facility through the international standard flange joint, or discharged to the outside sea through the overboard discharge pump.
The Holding tank is used for storage of raw sewage or remaining solid sludge disposed by the treatment plant. When it stores raw sewage, a certain amount of disinfectant can be added into the sewage. When the sewage reaches specified level, the cutting pump is started to convert solid sludge into small particle sludge by circulating repeatedly. The sludge can be transported to the reception facilities with the shore connection or it can be discharged overboard when the ship navigates in the non-restricted areas.
