Marine Sewage Treatment Systems

Preventative maintenance reduces the risk of unexpected breakdowns and increases machine reliability. Regular maintenance of your marine sewage treatment device is crucial for service life, safety, and operational readiness. Timely maintenance of your marine sewage treatment device and replacement of damaged MSD parts are essential for the safe operation of your marine sewage treatment plant.

The discharge of raw sewage into the sea can create a health hazard. Sewage can also lead to oxygen depletion and obvious visual pollution in coastal areas – a significant problem for countries with tourist industries. The main sources of human-produced sewage are land-based – such as municipal sewers or treatment plants. However, the discharge of sewage into the sea from ships also contributes to marine pollution.

Need your marine sewage treatment device serviced?

We are committed to helping you reduce compliance risks by servicing your vessel’s marine sewage treatment plants and other critical equipment, satisfying expanding environmental regulations — and thereby avoiding significant penalties for non-compliance. We are committed to helping you stay compliant with U.S. Coast Guard (USCG) and International Maritime Organization (IMO) standards.

Separator Spares & Equipment is committed to meeting our customers’ maintenance needs throughout the vessel’s life cycle. This includes servicing, planned preventative maintenance, operator training, equipment, and/or spare parts.

What is a Marine Sanitation Device (MSD)?

A marine sanitation device (MSD) is “any equipment for installation on board a vessel which is designed to receive, retain, treat, or discharge sewage, and any process to treat such sewage.” Under Section 312 of the Clean Water Act (CWA), sewage discharges from vessels are controlled in part by regulating the equipment that treats or holds the sewage (marine sanitation devices).

Need your marine sanitation device serviced? We are committed to helping you stay compliant with U.S. Coast Guard (USCG) and International Maritime Organization (IMO) standards. We offer a full range of services for marine sewage treatment plants (STP) and marine sanitation devices (MSD). We provide equipment, consumables, spare parts, and services for marine wastewater treatment.

What are the three types of Marine Sanitation Devices (MSD)?

Type I MSD is a flow-through device suitable for vessels up to 65 feet in length. These devices use a combination of maceration and disinfection to treat vessel sewage. After pulverizing the solids, the effluent is exposed to disinfectants (often chlorine tablets) that reduce bacteria levels to below the established limits under the Clean Water Act. In some cases, bactericide can be generated from the saltwater using special electrodes so that no added disinfectant products are needed.

Type II MSD is a flow-through device suitable for larger vessels. Type II MSD devices are biological systems; aerobic bacteria are used to treat the waste. First, sewage is aerated so that the bacteria already present in the sewage can thrive and begin to consume/break down the sewage as their food supply. As with the Type I devices, the remaining liquid waste is then treated via contact with chlorine tablets, UV disinfection, or other disinfection methods. Overall, Type II marine sanitation devices can achieve better treatment process levels than Type I devices because of the biological component of the system, as opposed to maceration.

Type III MSD is holding tanks that do not treat sewage onboard the vessel. These devices are designed to store sewage effluent while preventing overboard discharge.

 

Type I Flow-through treatment devices that commonly use maceration and disinfection for the treatment of sewage May be installed only on vessels less than or equal to 65 feet in length

Must produce an effluent with:

  • No visible floating solids
  • A fecal coliform bacterial count not greater than 1000 per 100 milliliters
Type II Flow-through treatment devices that may employ biological treatment and disinfection (some Type II MSDs may use maceration and disinfection) May be installed on vessels of any length

Must produce an effluent with:

  • A fecal coliform bacterial count not greater than 200 per 100 milliliters
  • No more than 150 milligrams of total suspended solids per liter
Type III Typically a holding tank where sewage is stored until it can be discharged shore-side or at sea (beyond three miles from shore) May be installed on vessels of any length No performance standard; must “be designed to prevent the overboard discharge of treated or untreated sewage or any waste derived from sewage.” 33 CFR 159.53(c) (PDF)(2 pp, 163 K)).

IMO resolution MEPC 227(64)

redFox-sewage-treatment-plantSeparator Spares & Equipment, LLC is the Authorized Marine Distributor for redFox Environmental Services for the Gulf Coast region.

RedFox Marine Sewage Treatment units are US Coast Guard Approved according to 33CFR Part 159. They are also IMO type approved Sewage Treatment Plants according to IMO resolution MEPC.227(64). MEPC adopted MEPC 227(64). This ostensibly changes the discharge requirements and test protocols that are adopted by Resolution MEPC 159(55). Their specific aim is to reduce nitrogen and phosphorous from the treated water, which will prevent the acceleration of nitrification of the seas.
