| Abstract | ||||
| In this study, characterizations of wastewaters produced from Dairy products facilities were investigated. 6th of October industrial zone has been selected as it is the biggest industrial city which includes 2000 registered companies distributed along eleven zones. Dairy industrial sector represents 12 % of total facilities (220 manufacturing facilities) .The main objective of this study is to estimate pollution load produced from dairy industry in different industrial area. Multiple Dairy products are represented such as milk, butter, cheese… etc. The analysis parameters , such as Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5) , Total Suspended Solids (TSS), alkalinity, turbidity, color and phosphorus. Final effluents were displaying higher values of organic matter than the allowed discharge limits according to the national standards. 90 % of the load from dairy industries is mainly of BOD and COD, which is caused by Lactose concentration. In addition, Cheese whey wastewaters have increased concentrations of BOD and organic matter. In case of discharge, this wastewater, without appropriate treatment, will contaminate water bodies, reducing the lifespan of sewage networks and the efficiency of wastewater treatment plant. Egyptian government has forced exceptionally strict rules Law 93 for the year 1962 and it's Ministerial Decree 44 for the year 2000 and the Egyptian Prime Minister’s law 1012 for the year 2018 for the cost of industrial waste purification. Finally dairy wastewater is heavily polluted with organic load and should be treated before discharging. | ||||
