With some experts predicting “peak phosphorus” in 20 to 40 years, biosolids will become an increasingly economically viable alternative to expensive commercial fertilizers.
Water Treatment Residuals
SYLVIS is knowledgeable and experienced in beneficial use opportunities for water treatment residuals.
Water treatment residuals are produced from the treatment of drinking and process water. Water treatment processes employ coagulants to remove inorganic and organic matter suspended in the untreated source water. The resulting product may be thickened liquid or a dewatered solid.
The aluminum and ferric oxides in the residuals can be used to moderate phosphorus availability and movement in soils either in direct land application or in combination with other residuals. As a result, water treatment residuals can be used to ameliorate nutrient management challenges in environments with excess available nutrients. They can also be used as feedstock in other industrial processes.
