Electroscan Treatment System

Electroscan Waste Treatment System – Proven Type I MSD Performance for Clean Discharge

The Electroscan by Raritan is the most trusted and widely used Type I Marine Sanitation Device (MSD) on the market, delivering reliable onboard waste treatment that meets strict EPA and U.S. Coast Guard standards. Originally developed in the 1970s in partnership with Diamond Shamrock, this system was the first to make advanced waste disinfection accessible to vessels under 65 feet—helping boaters protect the waters they love with every flush.

What makes Electroscan exceptional is its proven electrolytic disinfection process. When activated, the system uses salt water and a patented electrode plate design to generate hypochlorous acid, a powerful disinfectant that breaks down and neutralizes bacteria and viruses. A high-speed macerator grinds waste, ensuring maximum exposure to the disinfectant for effective, safe discharge.

Unlike early designs that relied on chlorine injection or excessive electrical current, today's Electroscan is engineered for energy efficiency and smart control. It monitors system status in real time, manages power consumption, and logs treatment data via serial output for compliance tracking. Independent testing shows the unit routinely achieves treatment levels well below the EPA's 1,000 coliform/100 mL requirement—often under 14 coliform/100 mL.

Designed for boats using saltwater for flushing, the Electroscan is a flow-through system that begins treating immediately after each flush, replacing treated effluent with new waste. It’s an ideal choice for vessels looking for a compact, effective, and environmentally responsible sanitation solution. For freshwater flush systems, Raritan recommends the Purasan EX.

With minimal maintenance and unmatched treatment reliability, the Electroscan is the smart way to meet legal discharge standards without compromising comfort or convenience aboard.
