Abstract

Abstract: Decentralized handlooms are being traditionally practised throughout India. Siripuram village known for traditional Pochampally/Ikat work was considered as a case study for detailed investigation towards providing a sustainable solution. Nearly 65% of village population solely depend on weaving and dyeing works as primary occupation based on the household survey and generated wash water of 127 KLD on an average from the dyeing operations. Initially, a topographical survey (Aerial drone; PHANTOM 4 RTK UAV) was carried out to understand the drainage pattern, elevations, contours and interlinked with domestic and dyeing functions. The characteristics of combined wastewater and dye wash water were studied at lab scale using sequential batch (SBR) operation under aerobic (SBRAe) and aerobic-anoxic (SBRAex) microenvironments. SBRAex microenvironment showed effective organic and nutrients removal due to infused anoxic microenvironment. Treatment studies depicted 76.2% of organic fraction, 73.3% of phosphate, and 81.6% of nitrate removal. Based on the lab scale studies a closed-loop decentralized effluent treatment system was designed to ensure zero-liquid discharge (ZLD).
