Abstract

A large amount of water can be recycled from the effluent generated by tannery industries. In this work, the treatment of tannery wastewater was investigated using polyethersulfone (PES) membranes modified with polyethylene glycol (PEG) and calcium chloride (CaCl₂). Membranes were prepared through the phase inversion method by adding various amounts of CaCl₂ to PES and PEG respectively. The effect of CaCl₂ on the characteristics of blend membranes such as morphology, water uptake, porosity, pure water permeability and hydrophilicity was investigated. Studies indicated that CaCl₂ addition had modified the membrane properties considerably. Tannery wastewater was efficiently treated using the modified PES membranes. Permeability of wastewater was considerably increased while the CaCl₂ was incorporated in the PES polymer matrix. All modified PES membranes showed moderate removal of biological oxygen demand, chemical oxygen demand, total dissolved solids, chlorides, sulphates, oil and grease for the tannery effluents.
