Knoxville selects ACTIFLO technology for wet-weather treatment

I. Kruger, a Veolia Water Solutions & Technologies company, won a contract for the Fourth Creek Wastewater Treatment Plant Phase 1 project in Knoxville, Tenn. Kruger will furnish two 9.6 mgd ACTIFLO systems to provide high-rate clarification during wet-weather events. These will be converted to a BIOACTIFLO System by adding contact stabilization. ACTIFLO is a ballasted clarification process that combines microsand-enhanced floc formation and settling. The process was selected after pilot studies demonstrated successful performance of less than 30 mg/L effluent BOD5 and TSS. The process is to go online by summer of 2013.

Ostara to install commercial nutrient recovery facility in Gwinnett County, Ga.

Ostara Nutrient Recovery Technologies won a contract with the Gwinnett County (Ga.) Department of Water Resources to install a nutrient recovery facility at the F. Wayne Hill Water Resources Center. The company’s Pearl process will help the county meet nutrient recovery and struvite scaling challenges and increasing operating efficiency. The technology recovers magnesium, phosphorus and ammonia from wastewater and converts them to environmentally friendly, slow-release Crystal Green fertilizer. The plant will also deploy the Ostara WASSTRIP process, which extracts phosphorus from sludge before it reaches the digesters, reducing struvite formation in the centrifuges, digested biosolids pipelines and digesters, and increases nutrient recovery by 60 percent.
