• Abstract:

  The Dairy Industry Generates Large Quantities Of Wastewater Containing High Levels Of Organic Matter, Fats, Oils, Proteins, And Detergents, Leading To Significant Environmental Concerns When Improperly Treated. Traditional Wastewater Treatment Methods Often Struggle To Meet The Stringent Discharge Standards For Such Effluents Due To Their High Pollution Load. This Project Focuses On The Application Of Membrane Bioreactor (MBR) Technology For The Treatment Of Dairy Effluent, Combining Biological Degradation With Membrane Filtration To Achieve Superior Effluent Quality. The Study Investigates The Efficiency Of The MBR System In Treating Dairy Effluent By Assessing Key Parameters Such As Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), And The Removal Of Pathogens. The Biological Component Of The MBR Consists Of Activated Sludge, Which Facilitates The Breakdown Of Organic Matter, While The Membrane Filtration Unit Ensures Effective Separation Of Solids From Treated Water. The Project Aims To Evaluate The System's Performance Under Various Operational Conditions, Including Hydraulic Retention Time (HRT), Mixed Liquor Suspended Solids (MLSS) Concentration, And Flux Rates. Preliminary Results Suggest That MBR Systems Can Achieve High Removal Efficiencies Of Over 90% For COD, BOD, And TSS, Thus Meeting The Required Discharge Standards. Additionally, The Project Explores Strategies For Addressing The Issue Of Membrane Fouling, Which Can Reduce The System's Performance Over Time. Techniques Such As Periodic Backwashing, Membrane Cleaning Protocols, Andoptimizing Operational Parameters Are Tested To Minimize Fouling And Maintain Membrane Efficiency. This Research Highlights The Potential Of MBRs As A Sustainable And Effective Solution For Dairy Effluent Treatment, Offering Advantages Such As Compact Design, High Treatment Efficiency, And The Potential For Water Reuse. The Findings From This Project Will Contribute To Advancing MBR Technology For Industrial Wastewater Treatment, With A Particular Focus On Its Application In The Dairy Industry, Promoting Environmental Sustainability And Compliance With Wastewater Regulations.
