Ultrasound Technology for Waste Sludge Treatment

Ultrasound Technology for Waste Sludge Treatment

Ultrasound cell disintegration is an promising technology for waste sludge treatment. The frequency of ultrasound is operated at 20 kHz or greater. It produces cavitation effect generating intensive shear force and free radicals for enhancement of sludge disintegration. Ultrasound can be readily combined with biological treatment units in wastewater treatment process to provide a simple and effective solution for waste sludge treatment with small footprint and significant cost reduction.
