MBR upgrade for California casino wastewater

Koch Membrane Systems Inc has been selected to provide Puron™ membrane bioreactor (MBR) modules for the wastewater treatment plant at United Auburn Indian Community’s Thunder Valley Casino in Lincoln, California, USA.

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 flow of 1.2 MGD (4,500 m³/d).

“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.

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.”
