Preparation characterization of Low cost high performance membrane For textile effluent treatment

Abstract

The development of India into a modern country is slow but the newlinepopulation growth is rapid. Air, water and food are the three important things newlinefor day-to-day life. Pure form of these three is must. Nowadays many water newlineresources and air in the environment are polluted due to massive increase in newlinepopulation growth, industrialization, and modern Urbanization. The discharge newlineof heavy metals, dyes, pesticides etc., are mainly polluting the water bodies. newlineIn current scenario the world is in the urge of treating the water bodies, newlinewastewater, and sea water to reduce the water scarcity level. Everywhere newlinewastewater and water treatment processes possess at least one separation newlineprocess in the treatment units. In this work, conventional treatment methods newlineand advanced treatment methods are discussed. Membrane separation process newlineis playing a main role in the treatment processes. The performance of newlinepolymeric membrane and the inorganic membrane is discussed based on the newlineliterature. In this work the detailed review is carried out about the membrane newlineprocesses, materials, fabrication methods, advantages and disadvantages. To newlineovercome the drawbacks of both membranes, the new innovative idea called newlinemixed matrix membrane is derived and discussed. newlineIn this study, Polyethersulfone (PES) membrane was prepared and newlinePES is replaced with 0.25%, 0.5%, 0.75% and 1% wt% of SiO2, ZrO2, ZrSiO4 newlineas different modifying agents separately. Phase inversion method is used for newlinemembrane preparation with N-methyl pyrolidone (NMP) as a solvent and newlineSodium Lauryl Sulphate (SLS) and water mixture as a non-solvent. The newlinemorphology and pore size were analysed by Scanning Electron Microscopy newline(SEM). Pore volume, porosity, water uptake, contact angle were determined newlineto find the hydrophilicity. Formation of t- ZrSiO4 increased the porosity of the newlinePES/ ZrSiO4 membrane. newline
