Magnesium Hydroxide for Anaerobic Digester

A recycled papermill treats approximately 1.4 million gallons of process wastewater per day. The wastewater has high BOD levels. Wastewater is processed utilizing an anaerobic digester followed by an aerobic activated sludge system. The activated sludge system is clarified with a dissolved air flotation clarifier prior to discharge. Urea and phosphoric acid are added to the system to provide nitrogen and phosphorus as nutrients. Caustic Soda was historically used to control pH and alkalinity in…
