Domestic Liquid Waste Purification and Recycling

Rapid industrialization and urbanization subsequently brought many variations in the environment and ecosystems in the world, as a result there is proportionate increase in the domestic waste generation in India. Growth of urban areas, increase pressure on local water supplies. Already, usage of groundwater aquifers by over half of the world population are being over drawn, as a result, it is no longer advisable to use water once and dispose of it, so reuse and recycling of water is must. For formulating a sustainable water policy, a reliable source of water such as Recycled water should be taken into account. Recycling and reuse of water should be made obligatory to reduce the huge pressure on demand of fresh water. Waste water from water intensive activities should be recycled and reused and make the reclaimed water available for use in the secondary activities either within or outside the locality, resulting in saving lot of water. The total quantity of water used by the domestic sections is much less than that for irrigation. However, the liquid waste released from the domestic sections has a huge amount of pollutants and is discharged at specific disposal points. Thus, the purification of liquid waste generated from domestic projects is of much more importance. The quantity of organic matter in liquid waste is of great importance due to its polluting potential. The availability of oxygen for fish and other aquatic organisms can be reduced due to direct discharge of this matter into water bodies. Here comes the Purification and Recycling of domestic liquid waste into picture. Water recycling, also referred to as water reuse or water reclamation, is an effective method of treating captured or conveyed wastewater and redistributing it to benefit other water dependent applications. Unlike traditional approaches where water is merely discharged as waste after use, water recycling provides a reliable local water supply, helping improve water conservation, cut energy use and costs, minimize diversions from local water bodies, and prevent water pollution 1 . The objective of this work is to study about domestic liquid waste i.e. sewage its purification and recycling. With the help of some case studies this paper gives information about the processes and various units of purification and how the waste water is recycled after getting treated and its application.
