Evoqua Water Technologies has been selected to provide a Dystor® dual membrane gas holder system to the city of Mansfield, OH as part of its Wastewater Treatment Plant (WWTP) upgrade project. Evoqua worked closely with its sales partner BissNuss Inc., on the project.
The City of Mansfield WWTP was looking to replace one of its anaerobic digester covers, an old steel cover which had stopped functioning and was no longer storing gas. Evoqua was contacted to assess the application and provide a potential solution. The Dystor dual membrane gas holder system was selected due to its ability to maximise storage of methane gas and as a result of a recent successful installation with consulting engineer, Jones & Henry.
Evoqua’s Municipal Products and Services division will replace the 77.5 ft secondary digester steel gas holder cover with a Dystor system. The Dystor system consists of an outer membrane that remains inflated in a fixed position, while the inner membrane moves freely as it stores or releases biogas. The Dystor system can hold up to six times as much gas as conventional steel digester covers, maximising the energy benefits of the anaerobic digestion process and providing significant cost savings.
