The modern nutrient recovery from used water is a three‐step process: removal of organics, nutrients, and other pollutants for further processing; concentrating/accumulating nutrients to high concentrations in a small liquid flow; and extraction and recovery of nutrients as a chemical nutrient product. The high concentrations of nutrients in the supernatant provide opportunity for nutrient recovery. Microalgae and phytoflora provide the best prospects for algal farms processing integrated resource recovery facility effluents and nutrient recovery from effluents. Traditional wastewater treatment processes may remove but do not recover nutrients except for nitrogen and phosphorus in sludge, which in most cases used to end in a landfill or soils with limited agricultural production. Nutrients can be concentrated during treatment into the liquid phase and into solids. In the chemical separation/accumulation, the goal is to separate the nutrients into primary sludge before biological treatment.
