Comparative Study on Anti-Fouling Properties and Application of Two PVDF Blend Membranes in Wastewater Treatment
Abstract:
The filtration experiments of two PVDF blending membranes were performed. The critical fluxes of PVDF/PMMA and PVDF/TPU blend membranes were measured by the flux-step method. Then tubular membrane module PVDF/PMMA and PVDF/TPU were used to treat alcohol wastewater. The anti-fouling properties of PVDF/TPU membrane module were better than those of PVDF/PMMA membrane module. The critical fluxes of PVDF/PMMA and PVDF/TPU membrane modules were 24 L/(m2∙h) and 22 L/(m2∙h), respectively. In the alcohol wastewater treatment, TMP and SJ of the tested membranes remained stable during this period and membrane module B was more stable than membrane module A. The CODCr removal rates of two membrane modules reached 48% and 58%, respectively. And the UV254 removal rates were 18% and 19%, respectively. Both the turbidity removal efficiency were more than 97% and the average effluent values were below 0.10NTU.
