Milorganite is the organic fertilizer obtained from recycled sewage. It contains 85% organic matter that helps nurture and nourish the vegetation in the gardens and lawns by feeding the soil's microbes. It is manufactured by the Milwaukee Metropolitan Sewage District, producing this fertilizer for many years.
The wastewater, which is collected is filtered to remove any contamination. Oxygen and microbes are then added to feed the organic materials in the wastewater. Then the waste products start to separate from the clean water when the microbes form lumps, which drop to the bottom. At the moment, it becomes easy to separate organic matter from grey water.
