Analysis Of Water Pollutions

  1. 1. Analysis of Water Pollutions MAJID MOHIUDDIN
  2. 2. Quantitative measurements of water pollution <ul><li>Physical, Chemical, Biological and Microbiological : </li></ul><ul><li>To assess water quality </li></ul><ul><li>To provide pure water to public for drinking, domestic and industrial purposes. </li></ul><ul><li>To choose the most effective heatment method for impure water. </li></ul><ul><li>To determine the efficiency towards natural purification. </li></ul><ul><li>To trace the origin. </li></ul><ul><li>To check efficiency, uniformity and consistency of treatment processes. </li></ul><ul><li>To analyze whether infection by microbial organisms. </li></ul><ul><li>To find out particular microorganism and to suggest preventive measures and effective disinfection procedures. </li></ul><ul><li>Sewage and waste waters are analyzed to determine the influence of them on receiving waters and to protect them from contamination. </li></ul>
  3. 3. Water Analysis <ul><li>One Part per million (ppm) = 1 milligram per litre </li></ul><ul><li> = 1 gm per cubic metre </li></ul><ul><li> = 0.1 part per hundred thousand </li></ul><ul><li> = 0.0583 grain per U.S. gallon </li></ul><ul><li> = 0.00833 pounds per 1000 U.S. gallons </li></ul><ul><li>One grain per U.S. gallon (gpg) = 17.1. parts per million </li></ul><ul><li> = 17.1 milligrams per lire </li></ul><ul><li> = 17.1 grains per cubic metre </li></ul><ul><li> = 0.143 pounds per 1000 U.S. gallons </li></ul><ul><li>Chemical and Physical analysis of Water </li></ul><ul><li>Bacteriological Examination </li></ul><ul><li>Biological Examination </li></ul><ul><li>Radiological Examinations </li></ul>
  4. 4. Measurement of water quality by chemical and physical examination of water. <ul><li>Chemical Substances affecting Potability </li></ul><ul><li>Chemical substances affecting Health. </li></ul><ul><li>Measurement of Toxic Chemical Substances. </li></ul><ul><li>Chemical Substances Indicative of Water Pollution. </li></ul>
  5. 5. <ul><li>Chemical Substances affecting Potability </li></ul><ul><li>Colour - Tintometer </li></ul><ul><li>Turbidity – Absorptiometer or Jackson’s Turbidimeter. </li></ul><ul><li>Odour </li></ul><ul><li>Taste </li></ul><ul><li>Temperature </li></ul><ul><li>Hydrogen ion concentration </li></ul><ul><li>Electrical conductivity </li></ul><ul><li>Solids </li></ul><ul><li>Suspended Solids </li></ul><ul><li>Dissolved solids </li></ul><ul><li>Acidity </li></ul><ul><li>Alkalinity </li></ul><ul><li>Free Carbon dioxide </li></ul><ul><li>Free chlorine </li></ul><ul><li>Chlorine demand </li></ul><ul><li>Calcium, Magnesium, Iron, Manganese, Silver, Zinc, Beryllium </li></ul>
  6. 6. <ul><li>2. Chemical substances affecting Health. </li></ul><ul><li>Ammonia </li></ul><ul><li>Nitrate and Nitrite </li></ul><ul><li>Cyanide </li></ul><ul><li>Sulphate </li></ul><ul><li>Sulphide </li></ul><ul><li>Chloride </li></ul><ul><li>Fluoride </li></ul><ul><li>Fluoridation </li></ul>
  7. 7. <ul><li>3. Measurement of Toxic Chemical Substances. </li></ul><ul><li>Cadmium </li></ul><ul><li>Copper </li></ul><ul><li>Chromium </li></ul><ul><li>Arsenic </li></ul><ul><li>Lead </li></ul><ul><li>Tin and Bismuth </li></ul><ul><li>Mercury </li></ul><ul><li>Detergents (anionic surfactants) </li></ul><ul><li>Oil and Grease </li></ul><ul><li>Carcinogens </li></ul><ul><li>Phenols </li></ul>
  8. 8. <ul><li>4. Chemical Substances Indicative of Water Pollution. </li></ul><ul><li>Dissolved Oxygen </li></ul><ul><li>Biochemical Oxygen Demand (BOD) </li></ul><ul><li>Chemical Oxygen Demand (COD) </li></ul>
  9. 9. BACTERIOLOGICAL EXAMINATION OF WATER <ul><li>BACTERIOLOGICAL TEST </li></ul><ul><ul><li>Total Count Test </li></ul></ul><ul><ul><li>E.coli Test or Coliform Test. </li></ul></ul><ul><ul><ul><li>Presumptive Test </li></ul></ul></ul><ul><ul><ul><li>Confirmed Test </li></ul></ul></ul><ul><ul><ul><li>Completed Test </li></ul></ul></ul>
