The experiment was done on the liquid part of separated manure in order to treat it with an activated-sludge treatment that would produce an effluent that could be disposed by irrigation or for direct discharge to the water-course. The treatment reduces the nutrients content, however the pathogen indicators remains relatively high and the effluent cannot be used directly for irrigation or directly discharge to the water-course. Two products (effluent, and solids resulting from the separation) have to be disposed and evaluated for their nutrient content and two different types of equipment may be needed to handle the liquid part and to handle the sludge
