Marine Black And Gray Water Processor

Marine Black And Gray Water Processor

1. Marine Black And Gray Water Processor Preface:

This marine black and gray water processor is applicable to treat the sewage, which means human body wastes and the wastes from the toilets on vessels , to meet the effluent standards of IMO MEPC.159（55), and discharge the effluent to overboard. It is also applicable to treat galley & shower drainage which is called “grey water” on condition that the “grey water” should be pretreated or should select a bigger capacity model to match with.

The processor belongs to the key devices for prevention of pollution form ships in seas and oceans according to the revised Annex IV of the International Convention of the Prevention of Pollution (MARPOL 73/78). The MEPC.2 (VI) resolution adopted on 3th, December,1976 is the present guidelines on implementation of effluent standards and performance tests for STP, which is called “old standards”. This device is according to the MEPC.159(55) resolution acted on 13 October 2006, which is called “new standards”. The convention (MARPOL 73/78)provides that all STPs installed on board on or after 1 January 2010 should meet the MEPC.159(55)resolution.

The SWCM type Ships Waste Water Treatment uses activated sludge, contact oxidizing and principle of biologic membrane to digest the organic pollutant, which can treat sewage effectively and reach at the IMO new effluent standard or other stricter requirements.

Comparison Differences

Crushing discharge pump

Brand	Foreign Famous brand	Domestic Brand
Pro& Cons	Long service life, stable operation and high processing efficiency.	The pump body is fragile, the service life is short, easy to damage, and the work is unstable.

Air pump(The air pump is composed of the main engine, air bag, base, lubrication, cooling and other components. The main components of the main engine are composed of main parts such as pump body, rotor and sliding vane.)

Brand	Foreign Famous brand	Domestic Brand
Pro& Cons	Long service life, stable operation and high processing efficiency.	The pump body is fragile, the service life is short, easy to damage, and the work is unstable.

MBR Membrane

Brand	Foreign Famous brand	Domestic Brand
Pro& Cons	Long service life, lower replacement costs	Short service life and high replacement cost

Disinfection device

Brand	UV	Medicine
Pro& Cons	Environmentally friendly, efficient, safe to operate, and does not produce harmful chemicals. However, the power consumption is large, and the UV lamp needs to be replaced regularly.	Economical and effective, with follow-up disinfection effect. But it is ineffective for some virus spores, produces odor, is affected by pH, and has disinfection by-products

3. Marine Black And Gray Water 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.
