The purpose of sewage treatment is to stabilize the organic matter that is present in sewage. STP plant manufacturer India brings this article to tell you how water becomes waste water. What makes water as waste water?
The sewage quantity and its characteristics are important factors. Detailed analysis of water waste is important for characterization of wastewater to create an economical and effective wastewater management programme. The programme includes the primary data needed for the process design that helps in deciding treatment methods, extent of treatment, assessing the beneficial uses of wastewater in a regulated and planned way.
Here are certain characteristics of wastewater-
Temperature helps in indicating oxygen transfer capacity of aeration equipment and biological activity rate. Lower temperatures affect badly, and thus right design and selection of technology for areas having such lower temperatures are needed.
2. Hydrogen Ion Concentration (pH)
pH of wastewater signifies development of septic conditions.
3. Odor and color
Waste water become stale, darker and gains foul smell with passage of time.
Sewage includes only 0.1% solids, yet you cannot neglect the nuisance caused by these solids as they are extremely hazardous and need proper disposal. They can be suspended or dissolved in fractions that can be subdivided into volatile and non-volatile solids.
Phosphorous comes from food residues in the domestic sewage. The increased use of synthetic detergents adds more phosphorous content to the sewage. Just like nitrogen, phosphorus is important nutrient for biological process.
Nitrogen generates into the domestic sewage by proteins, amino-acids, amines, and urea. Generally the sewage includes sufficient nitrogen to take care of the biological treatment requirements.
Excess of chlorides concentration in sewage than the normal chloride in water supply is used as an index of the sewage strength.
8. Toxic metals and compounds
Heavy metals like copper, cyanide, and chromium may find their way into sewage through industrial/hospital discharges. It is important to notice these compounds in the sewage and proper treatment should be done with biological process.
9. Grease and oils
Grease and oil is the poison present in the sewage that increases the cost of treatment and pose a disposal problem as well.
