WaterFox® Sewage Macerator

The new waterFox® macerator is designed for the offshore platform which does not require the sewage treatment unit. Regulations specify that waste solids must be no more than 1/4" in size.

Simply connect the waterFox® inline to the existing sewage line the unit is ready to operate.
