The City of Houston in Texas, USA has selected Veolia Water Technologies Inc’s Hydrotech Discfilter system for tertiary treatment at its 69th Street Wastewater Treatment Plant (WWTP).

The existing traveling bridge filters at the 69th Street WWTP are near the end of their life and need to be replaced.

The 440 MGD peak daily flow tertiary Discfilter system is designed to handle influent with a peak TSS of ≤ 100 mg/L, and produce an average monthly effluent of ≤ 10 mg/L. This upgrade to the current facility involves retrofitting the Discfilter system into the basins of the existing traveling bridge filters. The Hydrotech Discfilter system will include 19 units, each supplied with filter chassis as well as media and a backwash pump. Veolia will also provide spare parts, instrumentation and field services as part of the contract.

“The innovative Hydrotech design provides treatment within a small footprint and allows us to use the existing filter structure while increasing our filter capacity. The system’s design is user-friendly and allows operation and maintenance to be efficient and easy to perform. We will also be able to save in electrical and operation costs because of the efficiency of the process,” said Shannon Dunne, City of Houston.
