چکیده انگلیسی
The feasibility of using ultrafiltration (UF) to recover protein from poultry processing wastewater (PPW) after primary treatment was investigated. By using polysulfone membrane with 30,000 molecular-weight-cut-off, almost all crude proteins in PPW were retained, subsequently reducing the chemical oxygen demand (COD) in the effluent to less than 200 mg Lâ1. Similar to the processing of proteinaceous materials, the average fluxes reached only 100 L mâ2 hâ1. By identifying the optimal values of key operation parameters, including pH, volumetric flow rate, and transmembrane pressure (6.74, 683 mL minâ1 and 14 psi, respectively) using response surface methodology (RSM), the flux was improved to higher than 200 L mâ2 hâ1. Although severe membrane fouling was still inevitable after processing, flushing the membrane with a cleaning reagent was found capable of effectively restoring membrane performance.
