IMO Approved Sewage Treatment Unit Manufacturer

The IMO approved sewage treatment unit manufacturer and exporter, Chongqing Hi-sea Marine Equipment Import & Export Co., Ltd.

The sewage treatment unit is applicable to treat the sewage from the toilets (black water) and shower (gray water) on ships to satisfy internationalstandards for effluent discharge.

The unit can be used for sterilizing gray water on ships as well.

The unit adopts the principle of traditional aeration and contact oxidization biochemical treatment and chlorine disinfection, using activated sludge and soft stuffing medium, Due to the air pump stop and start occasionally, it can solve the nitration problem and overcome the sludge expansion caused by thread-like bacteria, which is also called 'cancer' in traditional continuous aeration treatment plant.
