Simultaneous Organic and Nutrient Removals from Industrial Dairy Wastewater Effluent by Integrating Membrane Bioreactor and Conventional Biological Treatment Process
- the Environmental Health Departments
Abstract
The objective of this work was to evaluate theeffectiveness of integrated biological conventional treatmentwith membrane bioreactor (MBR) system in removing organicand nutrients from dairy industry wastewater. A pilottreatment system including biological treatment and submergedMBR system was installed at Kuwait Institute for ScientificResearch (KISR) research plant. The integrated MBR systemwas operated at the following conditions: average influent flowrate of 1 m3/d, average sludge retention time (SRT) of 38 d, andaverage hydraulic retention time (HRT) of 2 h. The resultsclearly show the performance of the integrated system inremoving organic matters with an average removal efficiency of99% for both biological oxygen demand (BOD) and chemicaloxygen demand (COD). However, good reduction in nutrientsconcentration in the system effluent. The average reportedefficiencies on total nitrogen (TN), ammonium (NH4-N) andtotal phosphorus (TP) were 45, 44.8 and 67.1%, respectively.
