The Raritan Purasan EX2 Waste Treatment System (RARPST12EX2)fromNomadic Supply Company® is a USCG-certified 12V Type I Marine Sanitation Device (MSD) that treats sewage at the source, allowing safe discharge in authorized, non-zero-discharge waters. The Raritan Purasan EX2 Waste Treatment System (RARPST12EX2) utilizes a high-speed macerator, a streamlined tablet dispenser, and an air pump to sanitize waste with tablets, making it suitable for both freshwater and saltwater marine toilets. The Raritan Purasan EX2 Waste Treatment System (RARPST12EX2) was originally developed for freshwater lakes in Kentucky and has now 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 for boaters navigating both freshwater and saltwater environments.The Raritan Purasan EX2 Waste Treatment System (RARPST12EX2) Type I Marine Sanitation Device (MSD) has become increasingly popular with many users in both salt and freshwater. Raritan believes that treating a single flush at the source and discharging into tidal water is far more effective than risking having a holding tank dumped overboard when a pump-out cannot be found or is not functioning. Each user has unique needs when boating, and for many, a holding tank may be the best solution, while some prefer to treat and discharge. There are a few things to consider when choosing a Type I MSD.While Treatment is required within the three-mile limit, some areas prohibit discharge from the Raritan Purasan EX2 Waste Treatment System (RARPST12EX2). The areas that do not allow discharge of any type are called No Discharge Zones, and these zones are specific, at this time, to treated black water only. So, any vessel operator or owner should consider the amount of time spent cruising, the areas in which they will be cruising, and the availability of pumpouts. A holding tank should never be discharged overboard.The Raritan Purasan EX2 Waste Treatment System (RARPST12EX2) is a flow-through system, which means that the toilet is connected to the tank and the tank is connected to the thru-hull. With each flush of the toilet, the waste enters the tank, where a small amount of disinfectant is introduced to neutralize the waste. At the same time, an equal amount of treated waste is forced out of the tank and overboard.Raritan recognizes the diverse needs of boaters, and the Raritan Purasan EX2 Waste Treatment System (RARPST12EX2)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 thePurasan 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 Raritan Purasan EX2 Waste Treatment System (RARPST12EX2)is aType I Marine Sanitation Device (MSD)designed for use within the three-mile limit, where treatment is required before discharge. However, boaters must be mindful ofNo 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 inNDZs to determine the ideal sanitation solution for their vessel.
Advanced Flow-Through Design
The Raritan Purasan EX2 Waste Treatment System (RARPST12EX2)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 theEX 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:
- EnhancedDisinfectant 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-SpeedMacerator: 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, thePurasan EX 2now works seamlessly with most marine toilets, flushing with either saltwater or freshwater.
The Purasan EX 2 empowers boaters with:
- A cleaner, more convenient alternative to holding tanks.
- Compliance with waste treatment standards in regulated areas.
- A user-friendly system designed for effortless maintenance.
Purasan Improvements
The tablets used are very similar to the mixture used in commercial wastewater treatment plants. When the toilet flushes, a small amount of water is run over the tablets to create a disinfectant that drains into the tank, and a high-speed macerator inside the tank breaks down waste and ensures that the disinfectant comes in contact with the waste. This system does require the user to buy tablets to keep the system functioning properly. While the original Purasan remained largely unchanged for a long time, the newest version, the Purasan EX, has added a control that will notify the user when tablets need to be added.Another improvement in the Purasan EX over the original design is the addition of an air pump that forces the water down into the treatment tank. This makes mounting of the system easier and prevents the tablets from disintegrating too fast. While it was originally designed for just freshwater use and for use with specific toilets, it can now be used with almost any marine toilet. The only freshwater required is the water that passes over the tablets. However, toilets can flush with either salt or freshwater.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.
