Casino Expands Wastewater Treatment Plant

Koch Membrane Systems (USA) has been selected to provide PURON™ membrane bioreactor modules for the wastewater treatment plant at United Auburn Indian Community’s Thunder Valley Casino in Lincoln, Calif. The project will upgrade and expand capacity at Thunder Valley Casino’s existing wastewater treatment plant.

KMS provided 12 PURON PSH 500 modules, ancillary equipment, controls, engineering and technical services for installation in two new process trains and as replacements to an existing competitive double header module. The system is designed for a daily flow of 1.2 million gallons.

“Retrofitting existing systems with PURON modules is relatively easy and KMS has seen an increase in our MBR retrofit business,” said Imran Jaferey, vice president of water and wastewater at KMS. “The design of the PURON modules improves air efficiency and energy costs. The wastewater produced for Thunder Valley meets the stringent requirements for use of recycled water for on-site irrigation, required under California Code of Regulations Title 22.”

According to Bill Slenter, principal, HydroScience Engineers, Inc., which designed and managed the project’s construction, “We evaluated multiple membrane technologies and selected KMS based on our determination that it was a robust, quality membrane system with innovative features that would work well in the intended application. In addition, it was offered at a very competitive price.”
