Abstract: The novel filtration system for zebra mussels is comprised of an unit that is designed to allow users to prevent the infiltration of zebra mussels into drinking water systems having their intake pipes located in surface waters that are infested with the zebra mussels and their eggs. The filtration system for zebra mussels is comprised of a plurality of filters that include an inner pleated micron filter, and a middle wire frame for durability and an outer, course metallic screen. The filtration system is the form of a circular unit that is fitted around the head of a foot valve of the water intake line. A circular plate is located at the top and the bottom of the filters and is held together as a single unit with rods connecting the top and bottom circular plates.
