TOWSON, Maryland, Feb. 19, 2003 — USFilter will provide three General Filter MULTIWASH® AERALATER® packaged iron and manganese removal units to the Village of Byesville, Ohio.  The units will serve as pre-treatment to Memcor® CMF microfiltration equipment with chlorine resistant PVDF (Polyvinylidene Fluoride) membranes, purchased on an earlier contract.  The treatment equipment, valued at nearly $2 million, will be used to treat the village's well supply which the Ohio Environmental Protection Agency classified as ground water under the influence of surface water.

AERALATER® units are packaged aeration-detention-filtration systems to remove iron and manganese, which measure a combined 4.3 parts per million (ppm) at Byesville.  The three units will process a total plant flow of 2,430 gallons per minute (gpm).

The microfiltration system includes primary treatment with backwash waste recovery.  Effluent from the AERALATER® units is pumped through the primary membrane system to provide pathogen removal.  The backwash recovery system minimizes lost water in the plant and concentrates the backwash waste.

While both technologies boast several hundred installations, Byesville will be the first installation incorporating them in one treatment system.  The plant designed by W.E. Quicksall & Associates, Inc. of New Philadelphia, Ohio incorporates a control system provided by USFilter to monitor and control all operating aspects of the plant. 

"This plant clearly shows what USFilter can offer a customer," states Les Uhlmeyer, P.E., vice president of sales.  "Being the single source of all the major equipment simplifies everything from procurement through operation of the system."
