Point-of-use (POU) water treatment technology in developing countries and rural regions is more feasible than a centralized water treatment system due to the high cost of pipe distribution. The water filtration system can provide quick and easy access to water with low maintenance and higher pathogen removal among POU technologies. However, non-biodegradable polymeric materials for water filtration membranes raise environmental concerns due to their problematic disposal. There is increasing research on biode-gradable membrane material, but the validation of biodegradability is still lacking as measuring weight loss does not guarantee the complete mineralization of biodegradable membrane. This review aims to discuss various abiotic and biotic factors affecting polymer degradability in soil or compost, gather and evaluate existing studies on biodegradable filtration membrane and identify existing methods used to validate membrane biodegradability. Different kinetic models used to understand the biodegradation mechanism at different stages were studied. Factors affecting morphology and surface properties affect biodegradability. Membrane biodegradation follows a first-order model followed by a lag phase. Finally, future studies of biodegradable filtration membrane could include CO2 quantification and phytotoxicity studies, exploring different additives and membrane formulations to balance membrane performance and degradation ability, and lastly, conducting LCA and TEA to assess overall sustainability.
