Nano Filtration

Advanced membrane technology offering selective filtration—perfectly suited for removing hardness, organic matter, and specific salts from water streams.

Nano Filtration (NF) is a semi-permeable membrane process that serves as a bridge between reverse osmosis (RO) and ultrafiltration (UF), offering selective permeability to specific ions and molecules. It effectively removes divalent and larger ions, organic compounds, and pathogens while allowing monovalent salts such as sodium and chloride to pass through. This selective separation makes NF a highly efficient solution for softening hard water, reducing chemical oxygen demand (COD), and separating dyes and colorants in industrial applications.

Nano Filtration is widely used in industries like textiles, food & beverage, pharmaceuticals, and chemical manufacturing where partial salt retention, energy efficiency, and high permeate flow are critical. It serves as an excellent pre-treatment step before RO systems, enhancing membrane life and overall system performance. NF is also suitable for treating brackish water, removing micropollutants, and recovering valuable resources from process streams.

One of the key advantages of Nano Filtration is its ability to operate at lower pressures compared to Reverse Osmosis, resulting in significant energy savings. This makes NF an economically viable option for facilities aiming to reduce operational costs while maintaining effective contaminant removal.

At BK Hydro Tech Solutions, our NF systems are tailored to meet specific process needs with options for skid-mounted, modular, or containerized units. We use high-performance membranes and automation to deliver consistent water quality with low operating costs and minimal maintenance. Whether for standalone use or integrated water treatment trains, our Nano Filtration systems deliver sustainable and scalable solutions.
