Membrane technology encompasses the scientific processes used in the construction and application of membranes. Membranes are used to facilitate the transport or rejection of substances between mediums, and the mechanical separation of gas and liquid streams. In the simplest case, filtration is achieved when the pores of the membrane are smaller than the diameter of the undesired substance, such as a harmful microorganism. Membrane technology is commonly used in industries such as water treatment, chemical and metal processing, pharmaceuticals, biotechnology, the food industry, as well as the removal of environmental pollutants. After membrane construction, there is a need to characterize the prepared membrane to know more about its parameters, like pore size, function group, material properties etc, which are difficult to determine in advance. In this process, instruments such as the Scanning Electron Microscope, the Transmission electron Microscope, the Fourier Transform Infrared Spectroscopy, X-ray Diffraction, and Liquid–Liquid Displacement Porosimetry are utilized. Introduction Membrane technology covers all engineering approaches for the transport of substances between two fractions with the help of semi-permeable membranes. In general, mechanical separation processes for separating gaseous or liquid streams use membrane technology. Recent years, different methods have been used to remove environmental pollutants, like adsorption, oxidation and membrane separation. Different pollution occurs in the environment like air pollution, waste water pollution etc. As per industry requirement to prevent industrial pollution because more than 70% of environmental pollution occurs due to industries. It is their responsibility to follow government rules of the Air Pollution Control & Prevention Act 1981 to maintain and prevent the harmful chemical release in the environment. Make sure to do prevention & safety processes after that industries are able to release their waste in the environment. Biomass Based Membrane technology are one of the most promising technologies for use as a pollutants removal weapon, because it has low cost, more efficiency, & lack of secondary pollutants. Most probably polysulfone, polyvinylidene fluoride, and polypropylene is used in the membrane preparation process. These membrane materials are non-renewable and non-biodegradable as it will be harmful to the environment and create environmental pollution. Researchers are trying to find a solution to synthesize an eco-friendly membrane which avoids environmental pollution. Synthesis of biodegradable material with the help of naturally available material such as biomass based membrane synthesis can be used to remove pollutants. Membrane Overview Membrane separation processes operate without heating and therefore use less energy than conventional
