Treatment of Wastewater from a Food and Beverage Industry Using Conventional Wastewater Treatment Integrated with Membrane Bioreactor System: A Pilot-Scale Case Study

This study compares the performance of Hollow Fiber (HF) and Flat Sheet (FS) types membrane bioreactors (MBRs) for treatment food beverage (F&B) industry wastewater in a pilot-scale plant (WWTP). HF FS configurations were evaluated at two different Mixed Liquor Suspended Solid (MLSS) levels: 6000 mg/L 12,000 mg/L. The each configuration was terms Chemical Oxygen Demand (COD) Total (TSS) removals effluent quality measurement. transmembrane pressure (TMP), flux rate, silt density index (SDI) monitored calculated fouling assessment. results show that rejection rates COD TSS more than 84% MLSS levels. During study, recorded 0.3 bar pressure, which complies with recommended range (i.e., to three times chemical cleaning). On other hand, operates without cleaning, TMP value below 0.2 bar. It found values both systems within 40 L/m2/h. Analysis SDI revealed ranged between 1 2.38 allowable limit 3. Both MBR consistently achieved an 80% 95% rate TSS. Effluent measurement treated F&B this using WWTP integrated indicated good achievement compliance Malaysia industrial discharge standards.
