Abstract: A water filtration system for preventing a Zebra Mussel from entering a water system having a water intake line extending into an aquatic environment exposed to Zebra Mussels. The system contains an intake line connection for connecting the filtration system to the intake line; at least one water collection line extending from the intake line connection; a water intake line which is disposed sub-statantially parallel to the water collection line and which contains an orifice with a top surface and a copper screen recessed at least about 2.5 inches from the top surface; a first water filter and a second water filter, wherein each of these filters has a largest pore size that is small enough to prevent passage of an egg or veliger of Zebra Mussels; a a copper screen surrounding each of the first water filter and said second water filter; and a housing surrounding each of the water filters and including a first filter intake and a second filter intake.

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.
