Dystor® Installation Increases Gas Storage Capacity, Resulting in Significant Cost Savings for the City of Eau Claire, WI

A faulty secondary digester cover at a wastewater treatment plant was not providing sufficient gas storage for cogeneration. Siemens Water Technologies installed a Dystor membrane gas holder cover with support dome. The upgraded facility’s operating pressure was structurally compatible with existing covers, allowed for sludge level variance throughout the entire side-wall depth of the digester, and saved the city $9,000 a month in electrical costs.

Enhanced Nutrient Removal Achieved with OMNIFLO® SBR

The City of Fruitland, Maryland was in need of expanding the capacity of their wastewater treatment plant from 0.5 to 1.0 million gallons per day (MGD) while upgrading its level of treatment to include enhanced nutrient removal (ENR).

J-Vap Dewatering/Drying System Achieving Class A Biosolids

A shortfall in treatment capacity left the northeast Tennessee community of Mountain City under a state-imposed sewer-connection moratorium that hindered efforts to attract new housing, tourism and industry. Class B Biosolids produced on drying beds restricted options for beneficial use. Limited drying capacity on the drying beds influenced activated sludge waste rates, making process control a challenge.
