The PURASAN EX is a U. S. Coast Guard Certified Type I Marine Sanitation Device for use on unin-
®
spected vessels 65 feet and under. It must be operated within navigable waters inside the three mile limit
that are not declared Federal No Discharge Zones (NDZ) by the U.S. Environmental Protection Agency
(EPA). Other countries - check with local authorities.
The PURASAN EX is designed for recreational use and accommodates most marine toilets. The
®
PURASAN EX is available in 12 or 24 VDC.
®
DESCRIPTION:
Each time the transfer pump cycles an equal amount of previously treated waste is discharged. The pump-
ing action of the transfer pump moves the waste through the PURASAN EX and out.
®
Water is diverted to the Tablet Dispenser during the treatment cycle, creating a halogen solution during hold
time. After the hold time, the Drain Manifold and Air Pump turn on and the solution drains into the Treat-
ment Unit.The first chamber macerates to reduce particle size and uniformly mix the waste with injected
halogen solution. The second chamber mixes to ensure uniform treatment of its contents.
The Hold n’ Treat is designed to integrate both a Type I and Type III MSD (Marine Sanitation Device) to
provide the user with a system that will be legal in all areas.
All waste is stored in a holding tank and the treatment mode will determine how the waste is processed.
This system eliminates the need for pump-out stations in most areas.
