International Classification:

B01D 3502

US Classification:

210170

Abstract:

Disclosed herein are improvements to a water filtration system on a water intake line that prevent the infestation of Zebra Mussels in the water system. The water filtration system filters any water entering the water intake line through a filter having a largest pore size that is small enough to prevent the passage of an eggs or veliger of Zebra Mussels. To prevent accumulation of Zebra Mussels on the filters and the filtration unit, copper screens surround the filters and the water intake to the filtration system. The filters are also provided with threaded ends to facilitate easy and reliable removal and replacement of the filters when needed.
