Food Waste-Water Problem in Bangladesh and Electro Spun Nanofiber Membrane Technology: A Review

Abstract
The food industry plays a crucial role in Bangladesh’s economy, contributing around 12.92% to GDP. The food industry has undergone substantial changes in food processing technology in recent years. Water is required for various functions in food processing plants, including moving items, washing, processing, and cleaning. The results in the production of wastewater effluent, which is usually undesirable due to the high concentrations of suspended particles, bacteria, colouring agents, salts, fats, and oils, as well as chemical and biological oxygen demands. In addition, the sector has been characterized by poor business practices, like releasing raw food effluents into rivers and lakes, resulting in the ecological deterioration of adjacent locations. The main barriers to attaining a time and cost-effective treatment of effluence are insufficient availability of materials for effluent treatment plants (ETPs) in local markets, high chemical costs, and a high import tax of 26%.This overview describes the role of available membrane technologies for food wastewater treatment and assesses their effectiveness. Namely, Electrospun Nanofiber Membrane (ENM) technology is identified as an emerging science that is producing membrane materials with improved performance and efficacy in wastewater treatment. The higher porosity and the surface-to-volume ratio of ENMs offer advantages over conventional filtration devices. Compared to traditional membranes' 5-35% permeability, ENMs have a permeability range of around 90%.
