waste water, environment, sustainability

The present day speedy socio-economic development of humanity has most vigorously stimulated the change in nature. Technological advancement, if on one hand has bettered the life of humans on this planet; on the other hand it has sharply intensified the pollution in environment. Industrial waste or effluents seriously pollute the rivers, lakes and oceans, which includes inorganic and organic toxicants. Water is being contaminated with biological and industrial wastes. The treatment of waste water generated as sewage has become both an ecological as well as an economic necessity. India’s demand for energy is among the fastest growing in the world. Water availability and quality are paramount issues in India with urban demand for water exceeding supply by as much as 30 percent. The investigations over the years have observed that the presence of toxic chemical in ground water has manifested itself in various types of disease in human- being and adversely effect the plant growth. Discharge of chemicals from various industries causes hazardous effects on humans, animals and environmental balances. So the study of toxic chemicals is of great challenge. The present study summarizes the result of analysis of effluents of sewage being drained into Yamuna river, an important tributary of Ganga (our pious GANGA), in the region of eastern Haryana (INDIA). The sewage samples were collected at regular interval and were analyzed for suspended solids, BOD, COD, ORP and pH. The concentration of toxic metals has been determined. DHS (Down-flow Hanging Sponge) Bio Tower an innovative sustainable method for waste water treatment has been discussed.
