Process water from a food plant's cooling tower is often contaminated with airborne dust, debris, cardboard scraps, labels, and bacteria. These contaminates circulate through heat exchangers and chillers and significantly reduce the system's cooling ability.
Spray nozzles become clogged due to particulates in the system which sacrifices the quality of the product manufactured. The plant’s water supply from the municipality or from wells is often contaminated with dirt which causes unscheduled shutdowns for cleaning.
Rain Bird self-cleaning water filters provide the ultimate solution where dirty water is a problem.
