Its Main Uses

This machinery is primarily used to treat incoming grey water or black water that collects on a vessel. Grey water comes from the machinery, sink or shower that is located within the scullery. In usual circumstances the grey water is removed overboard and since it is not sewage it does not harm the environment; to take care of the situation the piping carrying the grey water is connected to a MSD. The black water comes from the toilets and it comprises of human wastes and this is considered to be sewage. Any sewage that is not treated cannot be disposed overboard. As per the rules laid down by the IMO, sewage that is not treated cannot be dumped into the ocean unless the ship or boat is at least 12 nautical miles away from the nearest port. This black water is treated by the MSD by using chlorine and then it is released overboard.

Different Types of Marine Sanitation Devices

Type I

This version of the machine has a flow running from a discharge setup and the sewage is processed by breaking down using chlorine. In this way the bacteria content is reduced substantially. This type of MSD leaves no traces of floating solids. The machine also depends on maceration and chlorination to break down bacteria.

Type II

In this type of Marine Sanitation Device, the sewage is reduced by using aerobic bacteria and other biological processes. The type two of the MSD thus depends on aerobic and biological digestion of any bacteria to treat the sewage.

Type III

This particular type is quite different than the other two. This device is a big storage tank that contains untreated or treated sewage water until the ship gets to a port. The sewage is deposited onshore and is treated further.
