Actiflo Carb enhances the removal of natural organic matter, taste and odor compounds, endocrine disruptors and pesticides with the combined benefits of ballasted clarification and the adsorption capacities of powdered activated carbon (PAC). It can be applied to both drinking water and wastewater applications. more
  • Actiflo Carb enhances the removal of natural organic matter, taste and odor compounds, endocrine disruptors and pesticides with the combined benefits of ballasted clarification and the adsorption capacities of powdered activated carbon (PAC). It can be applied to both drinking water and wastewater applications. more
  • Anita Mox is a moving bed biofilm reactor for treating wastewater with high ammonia concentrations (200 to 2,000 mg/L). With patented controls, it removes nitrogen from side streams—such as those from anaerobic digesters—with 60% less air than conventional nitrification and no supplemental carbon. This significantly reduces the energy need and cost of operation in the main plant.  more
  • Biostyr Duo is a first-of-its-kind integration of biological aerated filter and moving bed biofilm reactor (MBBR) technologies. Wastewater first flows through a dynamic MBBR media layer that provides a large surface area for biofilm growth and treatment. Flow then passes through the Biostyrene media layer, which provides additional fixed-film treatment and filtration as the water flows up through... more
  • Bio Thelys is an enhancement to anaerobic digestion. It is a two-stage, batch thermal hydrolysis process, utilizing high-pressure boiling of biosolids followed by a rapid decompression. This process’ capabilities include increasing existing digester capacity by two to three times, increasing biogas production, producing Class A biosolids and increasing dewaterability up to 40%. more
  • BNR processes with real-time dynamic controls reduce aeration energy by 30% compared to time-based controls. Ceramic membranes provide a 10% to 20% electrical savings compared to other drinking water membranes. Discfilters offer a 40% to 50% energy savings over alternative tertiary filtration suppliers. The biosolids dryer and energy-recovery system can recover 100% of the dryer heating needs. more
