Abstract

Water is an environmental, social and economic asset needs to be managed with the objective of conserving a common patrimony in the interests of the community at large. In spite of unprecedented advancement in technology, globalization and urbanization across the world, a vast number of developing countries are lagging behind in providing basic sanitation and adequate water supply to their people. Discharge of chemicals from various industries causes hazardous effects on humans, animals and environmental balances. Substantial efforts are being made to document, understand, and explain the science behind these issues all over the world. Our study is concerned with the measurement and analysis of sewage effluents of Karnal and Panipat city(Haryana State) being drained into Yamuna River an important tributary of our pious Ganga in the region of eastern Haryana(INDIA). The sewage samples have been analyzed for BOD, COD, Total nitrogen, ammonium, TSS, VSS, ORP and pH including the concentration of toxic metals [lead (Pb), chromium (Cr), cadmium (Cd), and arsenic (As)] in the collected samples from Panipat city .The UASB (Upward Flow Anaerobic Sludge Blanket) is one of the existing, economically attractive method for sewage treatment well suited for tropical and subtropical countries. Anammox process offers the possibility of removing ammonia nitrogen from wastewater with partial nitrification. The results of investigations show tremendous decrease in BOD and COD (up to 85 - 90%) on treatment with DHS (Down-flow Hanging Sponge) Bio-Tower, a combination of anaerobic (UASB) with aerobic (DHS) and advocating it as a self-sustainable sewage treatment for developing countries.
