Resuse of grey water

Abstract

Both water scarcity and the desire to increase the sustainability of domestic water resources have stimulated the search for efficient water use practices. These reasons drove our exploration of greywater—its characteristics and potential uses. Freshwater scarcity is a serious issue that affects at least one-fifth of the world's population and more will be affected due to population growth, mismanagement, increased urbanization and climate change. Innovative concepts and technologies are straight away needed to close the loop for water. Greywater reuse is one of the main alternatives for reducing potable water consumption in households, industries and commercial buildings. This article aims to review some of the principle greywater treatment technologies and their applications. This will also help to reduce the load on the sewage treatment plant It is absolutely necessary to study the Characteristics and behavior of grey water, this will help in determining the degree and type of treatment required to be study involves the analysis of pH value, total solids, total suspended solids, hardness, alkalinity, chloride, chlorine, BOD and DO. The samplings of the greywater will be done in different times of the day to have an average data of the measured parameters. A greywater treatment plant will be designed with the treatment units. Keywords: Characterization, greywater, treatment procedure. millions of people worldwide recycle greywater to irrigate tpeheir gardens and flush their toilets.
