Nanofiltration (NF) membrane is basically a membrane filtration-based process or liquid-separation technology that uses nanometer-sized through-pores. NF membranes have pore sizes of 1-10 nanometers, which is smaller than membranes used in microfiltration and ultrafiltration but larger than RO. NF provides a high rejection of multivalent ions, such as calcium, and a low rejection of monovalent ions, such as chloride. The nanofiltration technology is used to recycle wastewater due to the high flux rates and lower energy consumption than RO technology. In addition, NF is often employed in the manufacturing process for pharmaceuticals, textiles, dairy products, and bakeries.

Polymethacrylates, alkylated wax phenol, and alkylated wax naphthalene are the most commonly used additives. The fundamental purpose of using pour point depressants in a lubricant formulation is to enhance the characteristic properties imparted by the main components of the additive material. Pour point depressants have three basic functions.
