It neutralizes waste, making it sanitary and safe for boaters and marine life. Great design for all toilets in salt, fresh or brackish water.The Purasan EX 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.
