## Abstract

A water purification system with a centrifugal system and a frictional heating system consists of a centrifugal unit, a cavitation unit, a cooling condenser, a vertical shaft, and a pitot tube. The centrifugal unit and the cavitation unit are mounted along the vertical shaft so that the rotational movement of the vertical shaft is transferred onto the centrifugal unit and the cavitation unit. Non-potable water is directed into the centrifugal unit to separate heavy solids. Less populated water from the centrifugal unit is transferred to the cavitation unit via the pitot tube. The cavitation unit uses friction to generate phase change in the volume of less populated water which is then directed to the cooling condenser to produce potable water.
