ABSTRACT

In recent years, there are increasing concerns regarding environmental pollution due to the increased number of effluents from the factories and the increase in carbon footprints around the world. To reduce environmental pollution from the effluents, researchers have investigated the possibilities of employing membrane technology in industrial processes. The use of nanofiltration (NF) has proven to reduce energy and wastage of chemicals by recycling and recovery. Furthermore, NF processes are more energy-efficient as compared to traditional separation processes such as distillation. The aim of this chapter is to review recent developments of NF in food and biotech industry. The potential for NF utilization in vegetable oil processing, sugar and dairy industry, bio-separation and biorefineries is highlighted. Finally, challenges and future research in NF are addressed.
