ULTRA FILTRATION

At V R Technologies, our cutting-edge Ultra Filtration systems offer advanced water purification solutions. With precision and efficiency, our UF technology ensures the removal of microscopic impurities, delivering clean and safe water for various applications, from industrial processes to residential use.

Ultrafiltration (UF) is a membrane-based filtration process used to separate suspended solids, colloids, bacteria, viruses, and macromolecules from water or other fluids. It operates on the principle of size exclusion, where the membrane allows only particles smaller than its pore size to pass through while retaining larger particles.

• Membrane: Ultrafiltration membranes are semi-permeable barriers with pore sizes typically ranging from 0.001 to 0.1 micrometers (µm). These membranes are made of materials such as polysulfone, polyethersulfone, or other polymers. The pore size determines the molecular weight cutoff (MWCO), which defines the size of particles that can pass through the membrane.
• Pressure: The feed water is pressurized and forced through the ultrafiltration membrane. The pressure applied is typically lower than that used in reverse osmosis but higher than in conventional filtration methods.
• Size Exclusion: As the water passes through the membrane, suspended solids, bacteria, viruses, and other contaminants larger than the membrane's pore size are retained on the feed side of the membrane. Meanwhile, water molecules and smaller solutes pass through the membrane and are collected on the permeate side.
