A marine sanitation device (MSD) is a piece of machinery or a mechanical system that is dedicated to treat, process, and/or store raw, untreated sewage that can accumulate onboard water vessels. It does not refer to portable devices such as portable toilets.
The Jackal or MWMIK [a] (from "Mobility Weapon-Mounted Installation Kit") is a family of vehicles designed and developed by Supacat Ltd [b] at their factory in Honiton, Devon, UK, for use by the British Army and Royal Air Force Regiment.
The bilge water that collects here include drain water or leftover water from the boilers, water collecting tanks, drinking water and other places where water can not overflow. However, bilge water doesn't just include water drainage. Another system that drains into the Bilge system comes from the propulsion area of the ship.
The system may consist of a single pond or several ponds in a series, each pond playing a different role in the removal of pollutants. After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water ) if the effluent meets the required effluent standards (e.g. sufficiently low levels of pathogens ).
Marine outfalls for partially treated or untreated wastewater remain controversial. The design calculation and computer models for pollution modeling have been criticized, arguing that dilution has been overemphasized and that other mechanisms work in the opposite direction, such as bioaccumulation of toxins, sedimentation of sludge particles and agglomeration of sewage particles with grease.

Simple systems use stationary media, and rely on intermittent, gravity driven wastewater flow to provide periodic exposure to air and wastewater. A common moving media system is the rotating biological contactor (RBC), which uses disks rotating slowly on a horizontal shaft. Nearly 40 percent of the disks are submerged at any given time, and the ...
