Deep bed filtration is commonly used to remove oil from oily wastewater. The wettability of the filter media greatly influences the oil removal efficiency. A filter with a strong hydrophobicity and oleophilicity results in a higher oil removal efficiency. To improve the hydrophobicity and oleophilicity, ZnO nanoparticles and octadecyltrichlorosilane (OTS) were coated on quartz sand filter media. SEM,...
In this study, the Response Surface Methodology, RSM, was adopted to investigate effects of operational conditions including aeration intensity, fiber length and feed concentration. The membrane fouling rate was used to evaluate the effects on the membrane fouling. The results had shown that for one end suction fiber module the Membrane fouling rate (MFR) has been affected by the air sparging and...
In this paper, the effect of coagulation on membrane filtration resistance had been studied in the process of membrane filtration with dosing coagulants, analyzed the contribution of different membrane resistance in the membrane process, in order to find an effective way to control the membrane resistance. By Carman-Kozeny formula analyzed, voidage and deposited particle size of the composite cake...
In this paper, the relationship of membrane fouling rates and the operation conditions of Clarification Membrane process had been investigated with Response Surface Methodology (RSM). Base on the data of operation conditions experiment, including: filtration flux, backwashing pressure (the ratio of the pressure of backwashing/filtration), backwashing rate (the ratio of backwashing time/filtration...
