Fabrication of Tween-20 coated PVDF membranes for wastewater treatment: optimization of preparation parameters, removal and membrane fouling control performance

Abstract

In the present study, polyoxyethylene (20) sorbitan monolaurate (Tween-20) was employed as a surface coating agent for hydrophilic modification of poly(vinylidene fluoride) microfiltration membranes.

Ionic Liquids and Activated Carbon: Effective Materials for the Sustainable Production of Fresh Water from Salt Effluents (BRINE)

“…A module with two compartments separated by the membrane was adopted to carry out the experiments relating to the treatment of salt water by the DCMD process (Figure S2). Synthetic NaCl solutions and seawater at different temperatures (40,50,60,70, and 80 °C) were used to supply the source compartment. A membrane with an active surface area of 9.24 cm 2 horizontally separates the two compartments: source (feed) and receiving (permeate).…”

Efficiencies and mechanisms of the chemical cleaning of fouled polytetrafluoroethylene (PTFE) membranes during the microfiltration of alkali/surfactant/polymer flooding oilfield wastewater

“…6 Membrane separation has emerged as a promising alternative for oileld wastewater treatment due to its superior properties, including good selectivity, strong adaptability, and chemical composition retention. [7][8][9] Microltration (MF) is considered to be one of the most effective membrane applications among the membrane separation processes for oileld wastewater treatment. 2,3,10 However, the pH of the wastewater has been observed to exceed the tolerable limit of commonly used MF membranes, which signicantly shortens the membrane lifespan and increases operating costs.…”
