Algal Turf Scrubber® technology can be applied to point source discharges where additional nutrient reduction or effluent polishing is needed to meet water quality objectives.
Thirty-MGD aquaculture facility with integrated ATS treatment area. Point source applications can include managed discharges where additional nutrient reduction or effluent polishing is needed.
Point source applications may include municipal wastewater effluent, industrial wastewater, agricultural wastewater, aquaculture discharges, sprayfield return flows, rapid infiltration basin recovery flows, or other managed discharges where nitrogen and phosphorus loads can affect downstream waters.
ATS systems can serve as a polishing step following conventional treatment. By treating large flows across shallow attached-algae floways, ATS systems can support additional nutrient uptake, filtration, and biomass recovery after primary or secondary treatment has already removed much of the organic and solids load.
This approach can be especially useful where permitted facilities are working to reduce nutrient loads, meet more stringent discharge limits, support Total Maximum Daily Load (TMDL) implementation, or reduce impacts to groundwater, springs, lakes, rivers, estuaries, or coastal waters.
For wastewater reuse, sprayfields, and rapid infiltration systems, ATS technology may provide an additional treatment option where residual nutrients in treated effluent or recovered groundwater contribute to surface-water impairment. In these applications, ATS systems can be evaluated as part of an integrated treatment strategy developed with the project owner and engineering team.
