Solas & EC Approved SWCM-30 Effluent Treatment Plant / Marine Waste Water Treatment Plant

1.Application and standard of Effluent Treatment Plant / Marine Waste Water Treatment Plant 

This plant is applicable to treat the sewage, which means human body wastes and the wastes from the toilets on vessels and which is also called "black water", to meet the effluent standards of IMO MEPC.159(55), and discharge the effluent to overboard. It is also applicable to treat galley & shower drainage which is called "grey water" on condition that the "grey water" should be pretreated and should select a bigger capacity model to match with.

Marine Sewage Treatment Plant belongs to the key devices for prevention of pollution form ships in seas and oceans according to the revised Annex IV of the International Convention of the Prevention of Pollution (MARPOL 73/78). The MEPC.2 (VI) resolution adopted on 3 December 1976 is the present guidelines on implementation of effluent standards and performance tests for STP, which is called "old standards". This device is according to the MEPC.159(55) resolution enacted on 13 October 2006, which is called "new standards". The convention (MARPOL 73/78) provides that all STPs installed on board on or after 1 January 2010 should meet the MEPC.159(55) resolution.

2.Main Features of Effluent Treatment Plant / Marine Waste Water Treatment Plant 

  2.1 Adopting horizontal circular design,ellipse closures on both ends,pressure resistance and compact structure. 

  2.2 The device is adopted auto-control,and the compliance with the requirement of 24 hours unattended cabin.

  2.3 Adopting the "MBR" technology,devices allow to the narrow size,and solve the conflict of small space of cabin,but big volume of device.

  2.4 The intermittent aeration in bio-membrance tank and hollow fiber menbrane tank,form the process of "aerobic-anoxic",and resolve the problem of "nitrogen and phosphorus removal". 

  2.5 The device is adopting the principle of " air-lifting" to transfer the sludge from sediment tank and membrane tank to aeration tank,meantimes the "pump stops and air never stopped",so as the scale on the membrane surface comes down.Due to back flushing and clean the membrane"online" used technology patent,so the life of membrane can be prolonged at least 8-9 years. 

  2.6 "On-line" cleaning technology,making the dirt on membrane off automatically,recover membrane flux.It can be solved the problem of opening the cleaning or replacement of membrane difficultly caused by the small space in cabin. 

  2.7 The effuent after further treatment can be reached at the requirement of "water recovery".
