The Albuquerque Bernalillo County Water Utility Authority in Albuquerque, New Mexico operates a 76-million gallons per day (rated capacity) wastewater treatment plant that treats a daily average of five million gallons of sewage from New Mexico’s largest city and its surroundings.
One of the operations in the wastewater treatment process is the dewatering of the sludge stream produced after aerobic digestion. This separation occurs in the centrifuge room, where three continuous Alfa Laval G-2 Dewatering Centrifuges handle the task. The cake that comes off the centrifuges is mixed with green solids and sent to composting, while the liquor is rerouted to the intake of the wastewater treatment process.
