The existence of wastewater and the need for wastewater treatment is not a new problem. The production of excreta and urine is a natural part of human life, and has a history as long as mankind. In parallel to growing civilizations and increasing urbanity, and with the introduction of the water closet and centralized wastewater collection, problems related to large accumulations of wastewater has arisen. In centralized systems for wastewater collection one could also find other sources to wastewater than only domestic, such as storm water and industrial wastewater sources.
Wastewater is generally looked upon as a negative resource, both from an aesthetic perspective and because of its characteristic bad odour, and the fact that its main component …show more content…

The disease was gradually traced back to well-water supplies contaminated with human waste from cesspools and privy vaults. As a result of this development, water closets in larger towns were to a larger extent connected to storm sewers. On the other hand, the handling of one problem led to the introduction of another one: surface water pollution. A receiving water body will up to a certain level be able to render harmless the contaminants of discharged wastewater through dilution. Nevertheless, when the quantities of pollutants exceed the recipients critical level, they will possibly do harm to the surroundings. In densely populated areas this is much likely to happen. The solution to this problem is through treatment of the raw wastewater. During the late 19th and the early 20th century, there was an awakening in the development of centralized wastewater treatment systems, mainly in the United Kingdom and the United 4 States. As an addition to collection and discharge of wastewater, physical, biological and chemical processes for the wastewater treatment were introduced, for the removal of pollutants.

Climate of the area and production of the dairy plant are two major reasons, responsible for changing waste water character. This variation is not only from one industry to another dairy industry but also from season to season and even hour to hour. In land received waste water affect the soil quality and soil structure and part of waste water can also leach is to underlying groundwater and affect its quality. The problem is more serious, when it concerns waste water discharge before treatment from dairy or milk processing industry. It is one of the largest sources of industrial effluents in many countries like (Europe and India). Disposal of untreated water is rapidly becoming a major economic and societal problem faced by the dairy processing industry in many respects. Almost all the dairy factories are facing the problem of water treatment, disposal and utilization of the waste water. Disposal of waste water into rivers, land, fields and other aquatic bodies, without or with partial
