1.1 BACKGROUND OF THE STUDY
Water, one of the abundant compound found in nature is recovering approximately three fourth of the surface of the earth. Over 97% of total quantity of water is in the ocean and other over 2% is tied up in polar ice caps and glaciers and in atmosphere and as soil moisture, which is accessible.
Industrial and domestic water supplies often contain dissolved minerals, gasses bad smells and unsightly appearance that are objectable to the user and equipment and society in general. Usually there problem can be easily corrected by the use of water treatments. Frequently there can be several methods of correcting a given problems. The selection of the type of equipment and treatment depends on the seventy of the problem the amount of attention the user/home owner desires to give the equipment, the cost of the equipment performance.
It is very good idea to never undergo any circumstance select or install equipment on a private or public water supply without first estimate the degree of impurities in the water with the set standard from WHO (World Health Organization) for safety sake.
Amount of impurities in water is a major global problem which require on going evaluation and revision of water resources policy at all level include industrial and domestic water it has been identified that 14,000 people suffered various disease due to impure water consumption, 700 million in the whole world has no assess to drinkable water, 1000 India Children die of diarrhea sickness every day and some equipment are abandon for long time due to accumulation of impurities from water which affect the productivity of the nation and world in general and also environment for instance in China and other countries.
Thus, this research project is designed to asses impurities in industrial and domestic waste water, these impurities may include physical, chemical and biological which may interfere with subsequent raised of the waste water.
The purpose of this research project is to:
The scope of the study was to understand the general approach and methodology involve in assessing and estimation of degree of impurities in domestic and industrial waste water. Basically, using chemical, physical and biologically analysis. In determine all the pollutant in waste water and comparing them with recognized standard such as World Health Organization (WHO).
The major limitation of the study is the general unwillingness of industries in the disclosure of important information, unco-operative attitude of the working samples and time constraint was a limiting factor that proved a stumbling block for the smooth conduct of the research work.
The method of this research were achieved by carrying out some primary and secondary treatment and estimations of impure water. In some industries and domestic wastewater. The estimation used to characterized impure water varies from price, qualitative physical determination, biological determination and chemical determination of amount of impurities in both industrial and domestic waste water. Other research method includes.
The significance of the assessing of impurities in waste water is that the public health must remain the primary objective of waste water management. Thus waste water containing polluting substance mainly in solution such as electroplating industry, the amount of impurities depend on the type of industries which is generally expressed in terms of parameters such as pH, suspended solid, total dissolve, BOD, COD etc. It should also be noted that modern industrial waste water and domestic waste water may also contain radioactive substance, explosives, grease and oil, higher BOD, highly acidic or basic etc.
Thus, this research work will be beneficial for domestic and industrial uses (society in general).
