Meetresolution of MEPC.159.(55) enacted on October2006.
CCS,EC.BV ETC....
IMO Approval
Ship Bilge,port,dock ...
Features
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."MBR" technology, allow devices to narrow the size, and solve the conflict of small space of cabin, but big volume of device.
4.The intermittent aeration in biomembrane 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 airlifting to transfer the sludge from sediment tank and membrane tank to aeration tank, mealtimes 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, so the life of membrane can be prolonged at least 8 to 9years.
6."Online" 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"
Performance
* Capability of disposed sewage
a) Black water:excrement and urinefrom toilet
b) Gray Water: waste water form cooking room and bath room
*It Can be developed to a sewage recycling system
