Ship Sewage Treatment Plant
Product Description
Ship Sewage Treatment Plant marine sewage water treatment plant
Ship Sewage Treatment Plant
Specification
1,Adopting horizontal circular design, ellipse closures on both ends, pressure resistance and compact structure.
2,The device is adopted auto-control, and compliance with the requirement of 24-hours unattended cabin.
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.
4,The intermittent aeration in bio-membrane tank and hollow fiber membrane tank, form the process of “aerobic – anoxic”, and resolve the problem of “nitrogen and phosphorus removal”.
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” usd technology patent.
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.
7,The effluent after further treatment can be reached at the requirement of “water recovery”
