Acoustic Treatment and Waste water Treatment

Water resource is taken for granted in many developing countries and the condition aggravates in densely populated countries like India. Bellary Nala is one such stream in Belgaum which is used as a dumping site for disposal of municipal and industrial waste. We aim to characterize the combined industrial and municipal wastewater of Bellary Nala in terms of physicochemical parameters. The stream was divided into 3 stretches with a total of 10 sampling stations for investigation of self-purification capacity. Onsite analysis of crucial parameters such as temperature, pH, Total Dissolved Solids (TDS) and conductivity was carried. Collected data was analysed based on standard methods as per the American Public Health Association, 2005. The Bellary Nala was found critically contaminated (at stretch 2) with pollutants contributing to total dissolved solids (TDS), Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), chlorides etc., their concentration were significantly higher as compared to general standards for discharge of effluents. The study found that the water quality has considerably improved by the self-purification phenomenon at stretch 3.
