Full Description

A state of the art water microfiltration process within a water treatmentplant in Summit County, Utah, is on course to prove that recycled backwashwater from the primary treatment process can be used as drinking water. It isanticipated that the data collected during operation will show that the filteredproduct from the recycled backwash produces the same quality drinking water asthe primary treatment produces. During this innovative process, the overall plantwaste quantity is reduced from 10 percent to 2 percent of the total plantproduction. The backwash water used to flush the membrane units is discardedinto a flocculation tank and plate-settler system where it undergoes a clarificationprocess. This clarified water is then pumped into another microfiltrationmembrane unit dedicated to treating only the backwash water. The recycledbackwash water membrane unit's filtered product is then sent to the tank thatprovides the backwash supply water for the primary treatment units. In meetingthe highest standards set by the environmental and political community, thebyproducts produced in the recycling process are pumped to the wastewatercollection system, resulting in no on-site discharge.This project can yield significant results. Recently released studies havefound that if current trends continue, tremendous strain will be placed on waterresources over time. If as successful as predicted, the Summit County facility willintroduce a revolutionary way to preserve one of our most precious resourcesand commodities by operating with 98 percent recovery. This ecologically awareprocess would be more efficient, reduce cost and, most importantly, create aviable increase in potable water. Includes tables, figures.
