The Purasan EX Treatment System – 12V by Raritan offers a reliable and efficient solution for all your marine sanitation needs. Whether you sail in saltwater or freshwater, the Purasan EX ensures environmentally responsible waste management by treating waste at the source, eliminating the need for a holding tank.
Overview of the Purasan EX Treatment System
The Purasan EX is a Type I Marine Sanitation Device (MSD) designed to meet the diverse sanitation requirements of boaters. Initially developed for the freshwater lakes of Kentucky as an alternative to the Lectra/San system, the Purasan EX has gained popularity among marine enthusiasts for its effectiveness and ease of use in both salt and freshwater environments.
Why Choose the Purasan EX?
- Environmentally Friendly: Treats waste at the source, reducing the risk of overboard dumping when pump-outs are unavailable.
- Versatile Compatibility: Compatible with almost any marine toilet, allowing for flexibility in installation and usage.
- Enhanced Control: Features an advanced control system that alerts you when it’s time to add treatment tablets.
- Efficient Design: Incorporates an air pump to facilitate water flow into the treatment tank, ensuring optimal tablet disintegration and system performance.
System Operation
The Purasan EX operates as a flow-through system, seamlessly integrating with your marine toilet and tank:
- Each flush directs waste from the toilet into the treatment tank.
- A measured amount of disinfectant is introduced to neutralize the waste effectively.
- Simultaneously, an equal amount of treated waste is expelled overboard, ensuring minimal environmental impact.
Key Features and Improvements
Treatment Tablets
The system utilizes high-quality tablets similar to those used in commercial wastewater treatment plants. When the toilet is flushed, a small amount of water activates the tablets, creating a potent disinfectant that interacts with the waste. A high-speed macerator within the tank ensures thorough breakdown of waste and effective contact with the disinfectant.
- Tablet Monitoring: The Purasan EX includes a control mechanism that notifies users when tablet replacement is necessary, ensuring continuous and reliable operation.
Enhanced Water Flow
One of the significant advancements in the Purasan EX over the original Purasan model is the addition of an air pump. This feature:
- Facilitates easier mounting of the system on various vessels.
- Prevents tablets from disintegrating too rapidly, extending their effective life and reducing the frequency of replacements.
Compliance and Environmental Considerations
While in operation within the three-mile limit, treatment of waste is mandatory. However, certain areas, designated as No Discharge Zones, prohibit any type of discharge, including treated black water. When selecting the Purasan EX, consider the following:
- Cruising Areas: Assess the regions where you will be sailing to ensure compliance with local discharge regulations.
- Pump-Out Availability: Evaluate the accessibility of pump-out stations along your routes.
- Usage Patterns: Determine if treating and discharging waste suits your boating lifestyle or if a holding tank remains preferable.
Remember, holding tanks should never be discharged overboard, maintaining environmental integrity and compliance with maritime regulations.
Installation and Compatibility
The Purasan EX is engineered for straightforward installation, compatible with most marine toilets. It requires only freshwater to activate the treatment tablets, while the toilet itself can operate with either saltwater or freshwater flushes. This flexibility makes the Purasan EX a versatile choice for a wide range of marine vessels.
