At Ocean Envirotech LLP, we offer cutting-edge Ultrafiltration (UF) and Nanofiltration (NF) systems designed to deliver superior water purification for industrial, commercial, and municipal applications. These membrane technologies provide a high level of contaminant removal while maintaining efficiency and low operational costs.
Ultrafiltration is a pressure-driven membrane filtration process that removes:
Suspended solids
Bacteria & viruses
High-molecular-weight organics
Turbidity & colloidal particles
UF membranes typically have pore sizes of 0.01–0.1 microns, making them ideal for pre-treatment to RO systems or as standalone solutions in various sectors.
Nanofiltration sits between ultrafiltration and reverse osmosis in terms of filtration. It removes:
Divalent & trivalent salts (like calcium & magnesium)
Organic molecules
Pesticides, color, and hardness
Bacteria & some viruses
NF membranes offer partial demineralization with lower energy consumption compared to RO, making them suitable for softening and specific separation processes.
Membrane filtration is a technique which is used to separate particles.
Ultrafiltration UF and Nanofiltration NF are Membrane filtration processes which are used to separate particles from a liquid for the purpose of purifying it.
UF & NF are cross flow filtration processes there purified water passes though a membrane as a result of differential pressure driving force.
