Kubota MBR Wastewater Treatment Plant
|CLIENT: Kubota Tractor Corporation
|LOCATION: Grapevine, TX
eHT provided technical design of a new 50,000 gpd MBR wastewater treatment plant (WWTP), constructed in the City of Grapevine. Kubota Tractor Corporation (KTC) relocated its North American headquarters to the DFW area and requested eHT’s assistance to integrate an MBR-based non-potable reuse (NPR) program at their new facility, to maximize reuse of water used onsite. Kubota requested eHT’s support in this project due to eHT having more active MBR experience than any other engineering firm in Texas.
The MBR facility was designed to capture, treat and reuse wastewater generated onsite at the new KTC facility. The project included the construction of a new influent pump station, preliminary treatment consisting of fine screens and flow equalization, secondary treatment consisting of a new BNR biological treatment process and a new MBR solids separation and membrane filtration treatment process, hypochlorite disinfection, solids storage and offsite disposal. eHT also currently assisting Kubota with the design of a new reverse osmosis (RO) system to further remove color from the filtrate stream to improve the aesthetics of the reuse system used for toilet flushing.
