Nanofiltration (NF) membrane and its applications in water softening and purification has been reviewed.
NF membrane characteristics, separation mechanism, and fouling issues have been discussed.
NF membrane with small pores required more energy.
Further improvement is required to solve the fouling issue which is considered as a common problem.
Water treatment using NF can be considered as one of the promising alternatives for traditional treatment plants.
Surface water is the main source of potable water production around the globe. However, this source is projected to different pollutants from domestic, industries and farms. Therefore, producing drinking water with high-quality standards and minimizing the amount of organic and inorganic pollutants is required. Different technologies have been used and tested for drinking water production. Nanofiltration (NF) membrane is one of these technologies which can produce potable water with high-quality standards. However, the fouling issue remained the major problem facing membrane technology. Further, a membrane with small pores required more energy, but this issue can be solved using renewable sources of energy. In this paper, a brief review on NF membrane technology is presented in different ways including, NF membrane characteristics, separation and fouling mechanisms, and applications of NF in surface water treatment. It was observed that more improvement is needed to solve the fouling issue which is considered as a common problem in all membrane types. Additionally, the NF process was noted to be a promising method for surface water treatment and softening purposes.
