Purasan EX 2 Treatment System

Purasan EX 2 – Compliant Onboard Waste Treatment Without the Holding Tank Hassle

The Raritan Purasan EX 2 offers boaters a smarter, greener way to handle waste—without relying on holding tanks or marina pump-outs. USCG-certified as a Type I Marine Sanitation Device (MSD), the Purasan EX 2 allows legal, safe discharge of treated waste in approved U.S. waters, helping you stay compliant while reducing your environmental impact.

Ideal for coastal cruisers, liveaboards, and weekend sailors, this compact system treats each flush in real time—neutralizing bacteria and viruses with every cycle. The result? No holding tank odors, no risk of overflow, and no more worrying about pump-out facilities on your route.

The latest EX 2 model features an upgraded tablet-based disinfectant system that delivers more precise dosing and better consistency than previous liquid-based designs. It’s easier to maintain, stores well in seasonal conditions, and is perfect for boaters navigating both salt and freshwater environments.

Installation is designed with flexibility in mind. The Purasan EX 2 works with most manual or electric marine toilets, and its small footprint fits easily into tight compartments. Plumbing connections are straightforward, and once installed, the system runs automatically—activating the treatment cycle every time the toilet is flushed.

Unlike basic MSDs, this unit provides EPA-compliant treatment levels by combining maceration, advanced disinfection, and a timed treatment sequence. That means you get cleaner discharge and peace of mind, without compromising on convenience or water conservation.

If you’re ready to move beyond traditional holding tanks, the Purasan EX 2 is the eco-smart upgrade. It’s a trusted solution from Raritan, a marine sanitation leader for over 60 years.

Ditch the tank. Treat waste at the source. Stay compliant wherever you cruise.
