The Greasy Wastes Receiving Facility at the Jurong Water Reclamation Plant in Singapore required a proven solution for mixing thick and heavy plant sludge containing high levels of fats, oils and grease in two 8 metre diameter storage tanks. The sludge was to be kept in a fully mixed and preconditioned state in order to eliminate material floating on the surface. Pump Systems designed and supplied two Rotamix systems, each comprising of three Rotamix nozzle assemblies and one heavy duty Vaughan SP8N10 self priming chopper pump.
