The recycling of treated wastewater effluents is needed to achieve water security, where very low nitrogen (N) and phosphorus (P) levels must be achieved for wastewater to be effectively recycled. This research investigates a more sustainable and cost-effective N&P removal process from wastewater, benefiting the environment and improving the viability of wastewater recycling. Phosphorus is a limited resource worldwide and will be effectively recovered in the process to be used as a fertiliser. This project develops wastewater treatment process tools, solutions and management strategies that addresses the current challenges of how optimal nutrient removal and recovery from wastewater is achieved, enabling water recycling and saving costs.
