Water Purification for Dairy Processing

High-Quality Dairy Utilities

Uncontrolled contamination in dairy manufacturing takes its toll in many ways. With the many sources of contamination present in dairy plants, risk is high for product recall and its profit-reducing consequences of lost sales, lost product and lost brand equity.

Microbial and physical hazards are easily released into the final product by contact with equipment or process fluids. Dairy processors concerned about consumer safety and product image incorporate various type of filtration to remove microorganisms and other particulate or suspended materials from utilities such as air, water, steam and gas. 

Water Purification

The utilization of high-quality water is required in dairy to enhance and ensure product quality and image. The type and extent of filtration is dependent on the final use and pretreatment given to water. For example, the maintenance of sterile conditions during aseptic processing and packaging will require that all lubricating/cooling water used for the pistons and filling heads must be sterile.
