Abstract:
A water reservoir treatment system including:(a) a water circulation system including a water pump having an inlet side and an outlet side, a water conduit for conveying water from said water reservoir to the inlet side of said water pump, and a water conduit for conveying water from the outlet side of said pump to said water reservoir; (b) a vortex separator provided in said water circulation system for separating particulate matter from said water; and (c) a mechanical filter provided downstream of said vortex separator, wherein said vortex separator is generally tubular in construction and comprises an elongated â€œTâ€  junction comprising first and second vertically oriented coaxial longitudinal arms and one perpendicular horizontal arm, said arms having approximately the same internal diameter, at least said first longitudinal arm, measured from the center of said â€œTâ€  junction to the end of said arm, being at least four times the internal diameter of said first longitudinal arm, wherein at least one half of the inlet between the horizontal perpendicular arm and the longitudinal arms is blocked so as to provide a tangential inlet.
