  7. Forvariouspurposes..

  8. Percapitademand The total yearly consumption of water of a water supply Scheme divided by the population of that area and the num Of days in a year… Per capita demand = total consumption of water Population * 365

  9. 3.Qualityofwater

  10. Importanceoftesting Water quality testing is important because it identifies contaminants and prevents water-borne diseases. Necessity……. Controlling operation Purity determination Amount of impurities Type of impurities Quality determination Deciding various purification stages

  11. METHODS…. Physicaltest… Temperaturetest Colortest Turbiditytest Odourtest Specificconductivitytest Chemicaltest… Totalsolidtest Chloridetest Chlorinetest Leadtest Arsenictest Phvaluetest Fluorinetest Ironandmanganesetest Coppertest Dissolvedgasestest Calciumandsodiumtest

  12. 4.Watertreatment

  13. Steps. Screening Plain sedimentation Sedimentation with coagulation Filtration Disinfection Aeration 1.Screening A protective device provided To Exclude large size particle Is called screening… Types.. 1.Coarse screening 2.Fine screening

  14. .Sedimentation The process by which suspended particles Removed form water under effect of Gravity Called sedimentation. Types.. Plain sedimentation. Sedimentation with co-agulation

  15. Chlorination Chlorination is one of many methods that can be used to disinfect water. This method was first used over a century ago, and is still used today. It is a chemical disinfection method that uses various types of chlorine or chlorine-containing substances for the oxidation and disinfection of what will be the potable water source

  16. 5.Conveyanceofwater The pipes of different material are used in conveyance of w Some of them are….. oCopper lead pipe oCast iron pipe oGalvanized pipe oSteel pipe oP.V.C. Pipes oAsbestos cement pipe oConcrete pipe Copper pipe

  25. 8.Introductiontosanitation The used water or anything else like solid or semi solid whicjh is throw Finally in one form to the other is called waste……. Classification … Dry waste Semi solid or semi liquid Liquid waste In our research, we’ve come up with five frequently mentioned sanitation tips to prevent foodborne illnesses in food service and retail businesses. They are: Proper personal hygiene, including frequent hand and arm washing and covering cuts; Proper cleaning and sanitizing of all food contact surfaces and utensils; Proper cleaning and sanitizingof food equipment; Good basic housekeeping and maintenance; and Food storage for the proper time and at safe temperatures.
