Performance study of ceramic microfiltration membrane for oily wastewater treatment
Cross-flow microfiltration (MF) processes were studied with oily wastewater using a ceramic ( -Al2O3) membrane with 50 nm pore size. The nfluence of parameters such as transmembrane pressure (TMP), cross-flow velocity (CFV), oil concentration in feed, pH and salt concentration n the separation behaviors were investigated by the measurements of permeate flux, total organic carbon (TOC) removal e...
متن کاملFouling Behavior and Performance of Microfiltration Membranes for Whey Treatment in Steady and Unsteady-state Conditions
Whey pretreatment for protein purification is one of the main applications of cross-flow microfiltration before an ultrafiltration process. In this paper, the effects of the operating pressure and crossflow velocity on the membrane performance and the individual resistances in microfiltration of whey for both unsteady and steady-state conditions were investigated for two 0.45 μm mean pore size ...
متن کاملPreparation and Characterization of Microfiltration Ceramic Membrane for Oily Waste Water Treatment
This work highlights the preparation of ceramic membranes from a low-cost naturally occurring clay material viz. red mud. Additives like sodium carbonate, sodium metasilicate and boric acid was added in standard stoichiometric ratio with the processed clay material, imparting characteristic properties. Paste casting method was followed for fabricating circular disc shaped membranes with 50 mm× ...
متن کاملPreparation of blend hydrophilic PSF-SPEEK ultrafiltration membranes for oily wastewater treatment
Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...
متن کاملPerformance evaluation of mullite ceramic membrane for oily wastewater treatment using response surface methodology based on Box-Behnken design
Nowadays, oily wastewater is increasing along with the growth of various industries. So, wastewater treatment is necessary in order to protect the environment. In this study, a mullite ceramic membrane was prepared. Then, oily wastewater treatment with 200 mg L-1 concentration was investigated by the response surface methodology based on Box-Behnken design (BBD) using Design-Expert 7...
