Abstract

Every single Continent is facing water scarcity and is looking at all viable solutions for minimising overuse of scarce freshwater resources. Many of the water sources that keep ecosystem flourishing and feed a growing population have become stressed due to man-made and natural causes. These natural resources will take time to renew and revive to sustain current situation.Prudently use and wastewater treatment is the only sustainable way to minimise the loss. In order to meet man's enormous requirements, industrial, agricultural, and household activities rise in tandem with population growth. In terms of production, consumption, export, and growth projections, the food industries play a significant role in the economic growth of many countries. After the industrial revolution and rapid urbanization results in consumption of water and also generation of wastewaterwhich is significantly distinct in nature, toxicity, and treatability. Traditional wastewater treatment technologies have been successful in treating effluents for disposal to some extent throughout the years. However, in order to reuse treated wastewater for industrial, agricultural, and home applications, advances in wastewater treatment technologies areurgently required. Membrane technologyhas become a popular solution for recovering water from a variety of wastewater sources. This article investigates the most popular membrane methods for wastewater treatment, as well as its merits and demerits.in this paper, Membrane fouling, cleaning, and modules are also discussed with appropriate recommendations are suggested. Usually, some standard wastewater treatment procedures, such as chemical coagulation, adsorption, and activated sludge, have been used for effluent treatmentowing to its cheap operating and maintenance costs, aerobic waste water treatment as a reductive medium is gaining popularity. Some novel technologies like Membrane Process (MP) have key advantages over the other technologies. They can possibly support sustainable industrial growth by saving energy, minimize environment impact, declining capital cost and enhancing raw material exploitation.
