In 2019, the St. Albans Municipal Utility Commission replaced two major pieces of equipment at their wastewater facility located along US Route 60 in St. Albans, WV. The new ultraviolet (UV) disinfection system utilizes low-pressure high-intensity UV lamps contained within quartz sleeves to protect the lamps from the wastewater flow, and reduces fecal coliform levels to less than 200/100 ml for flows up to a peak hydraulic flow of 18.2 MGD.
The new belt filter press dewaters solids removed from the wastewater flow prior to being disposed of by landfill or by land application. The new equipment is a totally self-contained, factory assembled 1.5-meter effective width belt filter press.
The twin-belt press utilizes the combination of chemical conditioning of the sludge and compression of the solids with high pressure rollers and belts, thus producing a sludge cake in the 16-20% dry solids range. The cost of the replacement UV disinfection system and belt filter press was approximately $1.85 million.
