  • Dairy Industry 1 Syed Sajid Sohail,
  • COWS : Nine out of every ten glasses of milk consumed by people come from cows. BUFFALO: buffalo produce half of the milk consumed in India. Ghee, a kind of liquid butter, is made from water buffalo milk.(53/ltr) GOAT: Some people find goat's milk easier to digest than cow's milk. Fat globules in goat's milk are smaller than in cow's milk. (100rs/ltr) REINDEER: The fat content of reindeer milk is 22%, six times as much as cow's milk. It is the only source of milk in northern Scandinavia, because no other dairy animal can survive in such a cold, hostile environment. ( 3.99$/ltr) HORSE: Over 700 years ago, Mongolian warriors made a dried-out concentrated paste from horse milk. When. In southeastern Russia, people use horse milk to make a alcoholic drink.(1800 rs/ltr) CAMEL: In the hot desert, camel milk lasts longer than other types of milk. It can last for seven days at 86 degrees Fahrenheit (30 degrees Celsius), and will last for three months when properly refrigerated.(20 – 40 rs/ltr) YAK, DONKEY etc. dairy are also present 2
  • the density of milk varies within the range of 1027 to 1033 kg /m3 at 20° C. The freezing point of milk is usually in the range of -0.512 to -0.550° C with an average of about -0.522° C. The pH of milk at 25° C normally varies within a relatively narrow range of 6.5 to 6.7 The boiling point of milk is close to the boiling point of water, which is 100°C or 212°F at sea level, but milk contains additional molecules in it, so its boiling point is slightly higher.

  • Sources of Waste 1)Receiving station 2)Bottling station 3)Cheese plant 4)Butter plant 5)Casein plant 6)Condensed milk plant 7)Dried milk plant 8)Ice cream plant 9)Water softening plant 10)Bottle and can cleaning plant 9
  • Receiving station: farmers>large containers>transported to bottling or other plants Bottling plant: Raw milk> cooling >clarification >filtration >pasteurization > bottling Wastes: milk drippings and chemicals for cleaning containers and equipment Cheese plant: Cooled milk >placed in vat >starter and rennet are added > casein is separated > cheese bars Wastes : w/w for cleaning utensils and floor * starter= lactic acid 10
  • In the creamery process milk is heated to 30*c and cream is separated from milk Butter plant: Pasteurized cream > add selected ripened acid > churned @7- 10*c > butter milk is drained out> packed for sale Wastes : w/w cleaning churns , butter milk, small quantity of butter • Skimmed milk is sent for human conception • Milk powders are produced by drying • Spoiled milk is used to make casiens for some plastics 11
  • w/w characteristics pH ---- 6 to 7.2 Alkalinity ---- 600 mg/l Total dissolved solids ----- 1060 mg/l Suspended solids ----- 760 mg/l BOD ----- 1200 mg/l COD ----- 1600 mg/l Total nitrogen ------ 80 mg/l Phosphorous ------ 12 mg/l Oil and grease ------ 300 mg/l Chlorides ------ 100 mg/l 12
  • Treatment of w/w : Solid waste: Hardly any solid waste is produced by the dairy industry. * B.O.D / C.O.D > 0.6, i.e treated by biological processes like Trickling Filters, ASP, Oxidation Ponds • For better economics, the strength and volume of the wastes are reduced. This is done by: • Prevention of spills, leakages, dropping of milks from cans • Reducing amount of water from washing • Segregating the uncontaminated cooling water and recycling it • By utilizing butter milk and whey for production of dairy products 13
  • Effects of Wastes on the receiving streams: • w/w is basically organic and alkaline in nature • If not treated then rapid depletion of D.O of stream occurs • Growth of sewage fungi • It also carries mycobacterium causing T.B • It becomes acidic due to decomposition of lactose to lactic acid and is harmful to fishes = 30,000 to 80,000 rupees = 2,00,000 glasses of milk = 50,000 liters of milk = 5* (10,000 ltrs capacity) = 53rupees*50,000 = 26,50,000 rupees 14
