Wastewater management is very important for the sake of our environment and living being. The scarcity of water in the coming future and importance of recycling and reprocessing has increased the development of many wastewater management companies. All across the world, variety of businesses are shifting their focus on wastewater solutions. Wastewater treatment solutions are also requiring so as maximizing their competency. Basically wastewater includes food wastes, human wastes and chemicals. If this industrial and domestic wastewater is discharged without any treatment in the environment it will turn perilous and unsafe for environment and water creatures. Therefore, for a healthy living being it is vital to reuse and recycle the used water as at the sewage treatment plant water is treated to remove physical, chemical and biological containments from wastewater.

If there is the absence of main sewage pipes in some interior areas, wastewater is treated via septic tanks. Septic tank is a small-scale sewage treatment system wherein a water light container used to refine and partially treat wastewater. After wastewater becomes uncontaminated it is sent back to the ground water. If wastewater left untreated human beings and water creatures can be exposed numerous critical illnesses. Wastewater contains many infectious organisms present in contaminated water like spores, bacteria, viruses etc. Research's show that wastewater when discharged untreated is the reason behind many infectious disease. Multiple effect evaporators are used to distillate liquids multiple times with repetitive use of higher temperature vapors. Today, more and more industries are in a move to install multiple effect evaporators so as to register their contribution on pollution control and water conservation.

Unlike septic tanks, sewage treatment plants are large facilities that are used to treat oodles of waste water released from factories, big industries and mills. Besides, sewage treatment plants also treat water released from domestic residences. Principally, the process of water purification is of two types; industrial treatment and domestic treatment. There are many steps involved in wastewater treatment namely physical, chemical and biological processes. The initial process of wastewater treatment incorporates sedimentation, aeration and filtration. The deposition of solid waste is done during sedimentation process. In the aeration process, oxygen content is increased by mixing the waste with oxygen generated in aeration tanks. Now comes the third and last process of sewage treatment is disinfection wherein the sewage is cleaned by removing toxicity so that it turns out to be fit and potable. Wastewater treatment is aimed to protect the human population and environment. These plants are located close to densely populated urban areas. Dilution of degradable organics in wastewater is unsafe to river, streams, lakes and oceans. Many solid and harmful chemicals are present in the wastewater like nitrogen, bacteria and phosphates which can contaminate the environment badly.
