 Microalgae can be used to treat wastewater, converting nutrients into biomass and bioproducts. This process is more efficient when performed in high-rate algal ponds, which depend on environmental factors like temperature, light intensity, and photo-period. At optimal temperatures, these factors can increase biomass production and nitrogen and phosphorus removal from wastewater.
