Midwest Power Station saves on Chemicals and Reduces Operational Costs with Containerized Mobile Microfiltration System
An innovative water treatment design helped the Amereen Coffeen Power Station in Coffeen, Illinois go green with a packaged MF/RO system from Evoqua Water Technologies. The system cut the amount of chemical discharges going into a manmade lake from which it draws it cooling and boiler feed water and it improved water quality in the lake. The innovative microfiltration / RO containerized system design MF was also 40 percent less expensive than conventional technology.
To meet the power station’s need for treated water while a new system was being built, Evoqua deployed a temporary mobile water treatment system to the site. The system included a mobile pretreatment trailer consisting of duo-media; two combo RO trailers, which contained multi-media filtration and RO; one mobile deionization (DI) trailer; and two skid-mounted FlexTrex® deionization vessels for polishing the product water after the DI trailer. The amount of chemicals discharged to the lake has been reduced by approximately 35 percent, and plant maintenance has been reduced by approximately 3,000 man-hours per year.
