Modification and Enhancement of Hydrophilicity of Hollow Fiber Polymer Alloy Membranes with Sulfonated Poly (Ether Ether Ketone) for the Treatment of Oil Effluents Using the Membrane Bioreactor Process

Water pollution with petroleum compounds is one of the most important environmental problems in oil-rich countries, due to its adverse effect on soil, water, and human beings. The hydrophilic hollow fiber membranes were produced by polymer blending of polyamide imide and sulfonated poly ether ether...
