A side-stream particle precipitator system for the breakdown and removal of bio-materials and suspended solids in water cooling systems using a plurality of ionizer treatment units utilizing electric and electro-magnetic fields and a mechanical vortex precipitating system to remove particulate materials contained in the water complex as suspended solids. The system also uses high voltage electrodes for charging the water complex to breakdown laminar flow at the conduit walls to mechanically dislodge any build-up of bio-materials or chemical compounds along the walls resulting in an increase in thermal conductivity.
