Abstract

Effect of Two Waves of Ultrasonic on Waste Water Treatment

Kumar R, Yadav N, Rawat L and Goyal MK

In the area of water purification, ultra sonication offers the possibility of an efficient removal of pollutants and germs. Ultrasound treatment is one of several technologies that promote hydrolysis – the rate-limiting stage during wastewater treatment. The basic principal of ultrasound is based on the destruction of both bacterial cells and difficultto-degrade organics. In wastewater, various substances and agents collect in the form of aggregates and flakes, including bacteria, viruses, cellulose and starch. Wastewater is composed largely of the substances responsible for the offensive, pathogenic and toxic materials. In the present research work we found that the ultrasonic treatment is very effective for the waste water purification. The bacterial populations in sludge were decreased according to the frequency (35 KHz and 130 KHz) and time period (5, 10, 20 and 30 min). As the frequency and time period increase the bacterial population was decreased. It was also observed that 130 KHz frequency was more effective than 35 KHz. This technique would play a major role in sustainable development in a large scale of water purification.
