The purpose of this study was to establish a rationale for the cleaning of microfilteration (MF) membranes fouled by milk. Milk was processed using a hydrophilic GVWP membrane. Fouling is the most important problem associated with the membrane-based milk sterilization process. This is mostly due to the deposition of bacteria, fats, proteins, and minerals on the membrane surfaces. In the first part of this work, the factors affecting the chemical cleaning efficiency were studied. This includes the effect of concentration, temperature, cleaning time, and cross-flow velocity. A wide range of cleaning agents including acids, bases, and surfactant was used. Flux recovery (FR) was employed for presenting the cleaning efficiency. In the second part of this study, FR was optimized using response-surface methodology with a face-centered central composite design (CCF). This was employed to create the mathematical model and minimize the number of experiments. 相似文献

A numerical model was established to predict and optimise the chemical cleaning process of Polyvinylidene Fluoride(PVDF)Ultra filtration(UF)membranes with the results from the experiment that applied the Response Surface Method(RSM)and Central Composite Design(CCD).The factors considered in the experimental design were sodium hydroxide(NaOH)concentration,sodium hypochlorite concentration(NaClO),citric acid concentration and cleaning duration.The interactions between the factors were investigated with the numerical model.Humic acid(20 mg·L-1)was used as the model foulant,and chemical enhanced back flush(CEB)was employed to simulate the chemical cleaning process.The concentrations of sodium hydroxide,sodium hypochlorite,citric acid and cleaning duration tested during the experiments were in the range of 0.1%–0.3%,100–300 mg·L-1,1%–3%and 0.5–1.5 h,respectively.Among the variables,the sodium hypochlorite concentration and the cleaning duration showed a positive relationship involving the increased ef ficiency of the chemical cleaning.The chemical cleaning ef ficiency was hardly improved with increasing concentrations of sodium hydroxide.However,the data was sharply decreased when at a low level of sodium hydroxide concentration.In total,54 sets of cleaning schemes with 80%to 100%cleaning ef ficiency were observed with the RSM model after calibration. 相似文献

One-step cleaning method for flux recovery of an ultrafiltration membrane fouled by banknote printing works wastewater 总被引:5,自引:0,他引:5
A method was developed to clean ultrafiltration (UF) membranes fouled by banknote printing works wastewater.The cleaning agent was comprised of 0.7 wt.% NaOH, 0.8 wt.% Na2EDTA, 0.3 wt.% Turkey red oil and 98.2 wt.% de-ionized water. Membrane flux recovered adequately when the cleaning agent was circulated for 20–30 min at 1.5 m/s and 50–60°C. The membrane surfaces before and after cleaning were characterized by SEM/EDX. The spent cleaning agent was analyzed by TOC and ICP. The results showed foulants were removed from the fouled membrane by the cleaning. Pilot-scale experiments were also conducted to validate the efficiency of the cleaning method. This one-step cleaning method replaced an existing four-step cleaning method and was employed to clean OF units in banknote printing works wastewater plants. 相似文献
