Purasan EX 2 Waste Treatment System

The Purasan EX 2 is an innovative, USCG-certified marine sanitation device designed to provide reliable and eco-friendly waste treatment for boaters navigating both freshwater and saltwater. Originally developed for the freshwater lakes of Kentucky, this advanced system has evolved into a highly sought-after solution for its ability to treat waste at the source, ensuring clean discharge into tidal waters while promoting environmental stewardship.

Raritan recognizes the diverse needs of boaters, and the Purasan EX 2 offers a smart alternative to traditional holding tanks. While holding tanks are suitable for some, they pose challenges such as limited capacity and the risk of illegal dumping when pump-out facilities are unavailable or non-operational. With the Purasan EX 2, waste is treated immediately and discharged as compliant effluent, helping boaters avoid the hassles of full tanks or non-functioning pump-outs while maintaining responsible waste management practices.

Understanding Type I Marine Sanitation Devices

The Purasan EX 2 is a Type I Marine Sanitation Device (MSD) designed for use within the three-mile limit, where treatment is required before discharge. However, boaters must be mindful of No Discharge Zones (NDZs), where discharge of treated blackwater is prohibited. Navigators should consider their cruising areas, the availability of pump-out stations, and the time spent in NDZs to determine the ideal sanitation solution for their vessel.

Advanced Flow-Through Design

The Purasan EX 2 operates as a flow-through system, seamlessly connecting the toilet, treatment tank, and thru-hull fitting. During each flush, waste enters the treatment tank, where a precise amount of disinfectant is introduced to neutralize pathogens. Simultaneously, an equal volume of treated waste is discharged overboard. This efficient process eliminates the need for long-term storage, ensuring a cleaner and more convenient boating experience. New for the EX 2 is the elimination of the manifold that was a part of the old tablet dispensing system making the dispensing system much more streamlined and efficient.
Purasan EX: Engineered for Performance

The latest Purasan EX 2 is packed with enhancements to deliver superior functionality:

Enhanced Disinfectant Tablets: Inspired by commercial wastewater treatment technologies, these tablets create a powerful disinfectant that neutralizes waste on contact. A built-in control system alerts users when tablets need replacement, ensuring uninterrupted operation.
High-Speed Macerator: Integrated into the treatment tank, this macerator efficiently breaks down waste, ensuring optimal contact with the disinfectant for effective treatment.
Air Pump Integration: A newly added air pump improves water flow into the treatment tank, enabling flexible mounting options while preventing premature tablet disintegration.
Versatile Compatibility: While initially designed for freshwater systems, the Purasan EX 2 now works seamlessly with most marine toilets, flushing with either saltwater or freshwater.
