Waste stabilization ponds can effectively treat domestic wastewater through natural bioremediation processes involving bacterial consortiums and microalgae. Microalgae grow quickly in the ponds, absorbing nitrogen and phosphorus pollutants that would otherwise cause eutrophication. The microalgae also produce oxygen and remove heavy metals. The harvested algal biomass can then be processed into high-value bioproducts like biofuels. However, additional nutrients may need to be added to match the microalgae's requirements, and developing efficient harvesting technologies remains a challenge. Overall, waste stabilization ponds provide a sustainable way to clean wastewater while producing microalgal feedstocks for bioproducts.
