characteristics of wastewater
Water is very essential thing for the survival of human beings because man cannot live without water for a single moment. Without water life on earth would not exist. Man use water not only for drinking and culinary purposes but also for bathing, laundering and other domestic uses. It is difficult to imagine any clean and sanitary environment without water. Urban people discharges water in several ways. Urban drainage water comes from different household areas. It is effect on our aquatic environment.
The wastewater system begins where the urban water supply system leaves off. Analysis of urban drainage water is very much essential because maximum water comes from domestic purposes and it discharges different types of wastage which contaminates our water. The factors responsible for water pollution and directly effects our environment.
Different chemical properties such as pH, EC (Electrical Conductivity), TDS (Total Dissolve Solids), Na+, K+, Ca2+, Mg2+, Cl-, CO32-, HCO3-, and SO42- were measured. All stations water were found to be alkaline with pH > 7. Some stations were found to be high EC and high TDS, which exceed the standard level. Some stations were found to be very high chloride concentrations and high sodium concentrations, which also exceed the standard level. Calcium and bicarbonate were also high in water of some stations. Potassium, carbonate, magnesium and sulphate concentrations were low, which were within the standard level.
