The City of Houston, Texas, has awarded a contract to Veolia Water Technologies Inc. to supply a 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 replacement. Veolia’s Hydrotech Discfilter system was selected for the City’s tertiary filtration treatment upgrade following the evaluation of proposals to replace the filters by team of the City’s employees and their local consultant The team reviewed capital and long-term O&M costs in order to select a manufacturer based on the overall best value. Another key factor for Houston in the selection process was the efficiency of equipment in regards to operation and maintenance over the course of the technology’s life cycle.
The 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.
Houston Water has 40 wastewater treatment plants that collect and treat an average of 239 million gallons of wastewater per day.
Shannon Dunne, Senior Assistant Director who leads the Wastewater Operations Branch at the City of Houston commented:
“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.”
Veolia Environnement is listed on the Paris stock exchange. With over 163 000 employees worldwide, in 2016, the Veolia group supplied 100 million people with drinking water and 61 million people with wastewater services.
