5. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. READ MORE
