Removal of phosphorous from wastewater

摘要: Processes, methods and systems are provided herein for lowering the concentration of phosphorus in wastewater. The process includes adding a suitable amount an aluminum-based coagulant/flocculent, example, aluminum-silicate coagulant/flocculent product to wastewater while maintaining pH at between about 4.5 6.65. This step provides eventual effluent stream precipitated aluminum-based, phosphorus-containing flocs dispersed next involves physically removing, as by filtering, which is These steps able provide containing less than 0.03 mg total per liter disclosure also teaches novel carrying out process.
