Waste water treatment is essential to re use of used water. In this paper we discuss about the waste water treatment , process and various techniques used for the treatment process. Waste water treatment is also important factor for safety of the environment conditions. To make the environment free from hazardous conditions and to make the sustainable environment. It is also controls different types of pollutions in the water. It is eco friendly in nature. Waste water engineering is the branch of Environmental engineering. which deals with occurance, distribution and treatment of waste water and recycle use of waste water. It also used for study of design construction of structures related to supply of potable water towards public. To prevent water borne diseases from the water. It is also used for disposal of waste water by selecting suitable locations . the study of waste water is also important to understand the various types of pollutions in the soil. This knowledge helps to better usage of water and disposal of the water

The scarcity of water and increasing water pollution are the pressing challenge human being facing. Recovering water and valuable heavy metals is highly desired for treating heavy metal containing wastewater. We proposed a novel hydrate-based process to treat Ni2+ containing wastewater. The water recovery, Ni2+ enrichment factor, desalination efficiency were studied using this cyclopentane hydrate-based method. A water recovery of 43% can be obtained with a desalination efficiency of round 88% and an enrichment factor of 1.6. The desalination efficiency and the quality of the as-made water via the hydrate-based process can be further improved to above 99% via three-stage hydrate reaction. The proposed hydrate-based water treatment process may find wide applications in waste water treatment and heavy metal recycling.

The process of BaS reacting with Na2SO4 from waste water to generate BaSO4 is an ideal waste water treatment process, in spite of the shortage to generate lots of by-products, the dilute solution of Na2S. A way of using dilute Na2S solution to absorb SO2 is introduced in this paper. Some problems concerning this process were discussed.
