Process water in food companies must meet stringent quality, regulatory and economic requirements to allow the manufacturing process to attain its goals. Pall Aria microfiltration systems, long recognized for their use in purifying municipal water sources, have gained a solid place in food plants as a means of providing consistent and high water quality regardless of the source, upstream treatment, plant demand or season.
The fully backwashable Pall Aria hollow fiber membrane systems have provided cost savings and a technical solution at more than 100 food plant installations worldwide in a variety of incoming water, recycling and wastewater effluent applications. Whether for prolonging the life of downstream RO membranes, purifying incoming water for various uses within the plant, minimizing plant water usage by process water recycling or reducing the solids loads from plant water prior to discharge, Pall Aria technology is an investment in consistent quality water, which is critical to plant operations and profitability.
Regardless of the feedwater quality entering a facility, Pall’s durable polyvinylidene fluoride membranes deliver virtually particle-free water, with typical turbidity less than 0.1 NTU. When coupled with Pall’s integrated oxidative and coagulating pretreatment, the membranes efficiently remove problematic iron and manganese, 30% to 60% of natural organic matter and arsenic to levels of less than 2 ppb. Finally, combined with a multibarrier approach, the Pall Aria system achieves high levels of microbial, cyst and oocyst reduction.
