Abstract

The potential risks associated with the use of recycled water have become a matter of concern for many organisations which are recycling water. Out of the many reasons, the major ones are that they are not able to maintain the efficiency of the treatment plant and to meet the high energy demand of these plants. These problems have led to restricted usage of treatment plants by the industries hence they allow the waste water to bypass directly into the natural water bodies without any treatment. This work has taken into consideration the issue of river Yamuna in Delhi, which is one of the most polluted rivers of the world. It has been identified that Nazafgarh drain located in west Delhi has got a major contribution in the polluting Yamuna. The need of the hour is to find an innovative solution to resolve the problem of water recycling and offer a platform to the industries where the burden of treating their factory effluents is taken care of. This paper proposes a 1 MLD water treatment plant based on Soil Biotechnology which can efficiently treat the Nazafgarh drain water and make it fit for disposal into Yamuna. SBT is an eco-friendly and sustainable technology developed at IIT Bombay which provides all levels of treatment in a single evergreen set up open to atmosphere which is odorless, cheap, simple to operate, easy to maintain and could be set up within the area of habilitation.

Highlights

Since the existence of our mother earth, it has got a limited amount of resources, may it be land, water or air
The sludge is discharged into nearby drains which eventually pollute some other water resource, as in Sikandara water treatment plant, Agra, where sludge is discharged into river Yamuna
The effluent parameters are in accordance with IS2490 (Part I)-1974 which gives tolerance limits for industrial effluents discharged into inland surface water

Summary

INTRODUCTION

Since the existence of our mother earth, it has got a limited amount of resources, may it be land, water or air. Water recycling has become a compulsory vertical to run a civilization efficiently and to meet the unbound needs of the growing population To serve this purpose, many conventional technologies like ASP (Activated Sludge Process), UASB (Upflow Anaerobic Sludge Blanket process), Physco- Chemical process etc. The question arises here, that if we have methods to treat waste water why we are polluting the precious water resources by disposing raw sewerage and untreated industrial effluent waste. The answer to this is that the construction, operation and maintenance of the plants based on above mentioned conventional technologies and many other mechanical methods is quite difficult to be undertaken and to sustain. A solution to all these problems is Soil Biotechnology, discussed
