This wastewater treatment technology has been utilized by Red Fox for over (25) years. This design is utilized on vessel applications. The process used by the MSD involves the same three steps as the conventional unit, but the clarifier operates under a fluid head pressure allowing flocculation and settling of the solids in the clarification chamber to occur even when the vessel is in motion:

  1. Aeration: Supports naturally occurring bacteria that eliminates the waste.
  2. Clarification: Causes the separation of the bacteria sludge from the treated water.
  3. Disinfection: Eliminates the presence of any living bacteria before discharge of the effluent into the environment.

Standard Marine Sanitation Device offers these benefits:

  • Applicable for processing 100 to 9000 gal/day - or crew sizes from 2 to 450.
  • USCG/IMO certified Type II MSD and also meets EPA regulations.
  • Offered in our standard configurations or custom designed special configuration to meet the customer's specifications and space limitations.
  • Low maintenance - Very few moving parts and requirements for maintenance. If maintenance or repairs become necessary, no special tools are required.
  • Low power/utility consumption.
  • No odor.
  • Option of a chlorine generator.
  • Reasonably priced.
  • Operates with fresh or saltwater.
  • No sludge is developed.

System Principles & Unit Diagram

The first operation is a coarse screening process. As the influent enters the sewage treatment unit, it passes through a bar strainer. This strainer will catch any large trash such as rags, plastic bags, etc., and prevent it from entering the system.

The second operation is aeration. As the sewage passes through the bar screen, it flows into the aeration chamber where the incoming raw sewage is mixed with the fluid in the chamber that contains a large concentration of very active aerobic bacteria that consume the organic waste material in the sewage. Air, which is used to keep the solids suspended and support the aerobic bacteria, is provided to the chamber by utility air or an optional air blower system.

The third operation consists of clarification and settling. The displaced liquid then travels into the clarification chamber where the chamber is placed under a fluid head pressure allowing the sludge to flocculate and settle to the bottom, even when the vessel is in motion. This settling process separates the sludge from the clear liquid allowing only clear water free of waste to escape out of the chamber.

The fourth operation is the disinfection process. This chamber allows the fluid to pass through a chlorine mixture or an ultraviolet system in areas where chlorine disinfection is not allowed. It then retains the fluid in this chamber until all the bacteria that were allowed to pass through the previous chambers are killed off.
