Decentralised Wastewater System and Enhancing Green Cover

Abstract

Abstract

Water is one of the most vital natural resources for all living beings on earth. The availability and quality of water always have played an important part in determining not only where people can live, but also their quality of life. On the other hand, wastewater is generated from various industries and from domestic use. The capacity of sewage treatment is much lesser than production, so, remaining sewage is directly discharged into streams or rivers resulting towards increase in pollution of water, which directly or indirectly affects the human and aquatic life as well as crop cultivation in agriculture. The root zone treatment system is one of the low cost methods to treat wastewater. With the help of this system, we can treat the wastewater with best results. The root zone system is the best possible alternative to centralized wastewater treatment system. Because of treatment at production level, the load on conventional STP is reduced by a huge amount. In addition, there is considerable saving in energy due to elimination of collection, transportation and treatment processes required in case of decentralized treatment method. To achieve this goal, we implemented a model in our campus to study the various aspects such as temperature effect, water quality; and related this study with our collage building. We had set up a reactor in which we implemented root zone technique and carried out lab analysis of reactor outlet sample for number of parameters. We considered flow rate as the main factor for designing our system. Therefore, keeping the detention time constant and changing flow rate we found out the change in different parameters. The optimum values are those when we get best results with maximum flow. After the results, we conclude that this model can be installed on domestic, commercial and institutional buildings. In addition, after the treatment, the treated water can be used for flushing, gardening, etc.
