Summary: Phycoremediation using algae for wastewater treatment is a smarter and more sustainable approach compared to classical treatments, as it removes contaminants while providing nutrients to support algal growth. This method effectively removes phosphates, nitrates, heavy metals, pesticides, hydrocarbons, nitrogen, and phosphorus from wastewater, while also inhibiting the proliferation of pathogenic bacteria. Open pond systems prove to be ideal for phycoremediation in developing countries due to their low maintenance, simple design, and reduced carbon footprint.

Summary: The rapid development of the aquaculture industry has led to a significant increase in aquaculture wastewater generation. Microalgae bioremediation could be a cost-effective and environmentally friendly method for treating aquaculture wastewater and producing valuable microalgal biomass. This study investigated the feasibility of using microalgae to treat brackish wastewater generated from a commercial tilapia farm in Qatar. Four candidate strains (Haematococcus sp., Neochloris sp., Monoraphidium sp., and Nostoc sp.) were shortlisted based on their nitrogen assimilation, biomass yield, biomass quality, and ease of harvesting. Among them, Neochloris sp. showed the highest biomass yield and could potentially be a suitable candidate for aquaculture wastewater treatment.
