Improving effluent pond water quality top priority at zero-discharge wastewater facility

The Hornsby Bend Biosolids Management Plant (BMP) processes all of the solids generated at Austin Water’s wastewater treatment facilities—up to 2.7 million gallons each day! The facility’s solids treatment processes generate two liquid streams. Centrate from the thickening process is treated at the sidestream treatment plant before discharge, and a high-ammonia filtrate from dewatering currently discharges to irrigation ponds. In addition to irrigating more than 500 acres of crops on site, the ponds also host a variety of migrating birds, making the BMP a premier birding hotspot in Texas.

To support their goals of reducing the ammonia and total nitrogen concentrations, the City of Austin engaged us to design an ammonia removal facility using Veolia’s ANITA™Mox deammonification technology. Known for its resiliency and efficiency, this technology will help the City integrate their reduction goals into Hornsby Bend BMP’s processes.

With an anticipated peak flow capacity of over one million gallon per day, it will be among the nation’s largest sidestream deammonification facilities and the first of its kind in the state of Texas.
