TEXTILE MILL WASTEWATER TREATABILITY STUDIES BY SOIL AQUIFER TREATMENT SYSTEM IN CONJUNCTION WITH NATURAL ADSORBENTS

Water resources around the world are under increasing pressure from the rapidly growing demands of rising population and industrialization. It is not only the depletion of quantity but also the quality is deteriorating due to indiscriminate discharge of untreated industrial waste waters and sewage generated from the community. Therefore treatment of wastewater for disposal and reuse is necessary for safe and sustainable environment. Several treatment techniques are adopted for better management of wastewater. In the present study Soil Aquifer Treatment System is adopted for wastewater reclamation for potable and non-potable uses. Textile Mill wastewater was used for experimentation to assess the treatment efficiency of SAT system in treating these wastewaters under varied experimental conditions. Clayey sand and silty sand are the two soils used for experimentation along with the Peepal leaf and Almond leaf has the adsorbents. Removal efficiency of chloride BOD and COD was maximum in clayey sand in conjunction with peepal leaf has adsorbent. Where in Colour and TDS removal was maximum in clayey sand when compared to silty soil and soils in conjunction with adsorbents.
