Marine Wastewater Processor

Marine Wastewater Processor

1. Marine Wastewater Processor General:

The marine wastewater processor belongs to the key device for prevention of pollution for ships in seas and oceans according to the revised Annex IV of the International Convention of the Prevention of Pollution (MARPOL 73/78).

This device is according to the MEPC.227(64) resolution enacted on 5th, October, 2012. Which only used to the "black water" from toilet fecal sewage. In the treating process, to add any dilution water, gray water (from washing room), and sea water are forbidden. This device is also not suit for the passenger vessels which on the Baltic Sea. This device is regardless of the total nitrogen and total phosphorus performance index requirements.

This device is apply to install on the below vessels later 1st, January, 2016:

(1) All areas of the vessel (expect passenger vessel);

(2) The passenger vessel beyond of the Annex IV of the International Convention of the Prevention of Pollution (MARPOL 73/78 ).

2. Marine Wastewater Processor Advantages:

(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, 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 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, 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) "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 reuse.
