Sewage Treatment Plant

1. Sewage Treatment Plant Preface

The sewage treatment plant is applicable to treat the sewage from the toilets on ships to satisfy internationalstandards for effluent discharge.The plant can be used for sterilizing gray water on ships as well.

The device 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.

2. There are two series device for you choose:

(1) The SWCM series device, which is Membrane Biological Reactor (MBR) device. Meeting the effluent standards of IMO MEPC.159(55).

(2) Biochemical method device, which is the old standard device with lower cost, meeting MEPC.2 (VI) resolution. We call it SWCB series device.
