Advanced Membrane Filtration: Understanding MF, UF, and NF Systems
In modern water treatment, one size does not fit all. At Keshav Chemicals and Engineering, we specialize in the design, installation, and maintenance of specialized membrane filtration plants. Whether you need to remove suspended solids, bacteria, or specific dissolved ions, our Microfiltration (MF), Ultrafiltration (UF), and Nanofiltration (NF) systems provide the precision your industry demands.
Microfiltration (MF) Plants
The First Line of Defense
Microfiltration is typically used to remove large suspended solids and primary turbidity.
• Pore Size: $0.1$ to $10$ microns.
• Best For: Pre-treatment for RO systems, removal of algae, sediment, and large bacteria.
• Application: Wastewater recovery, dairy processing, and cooling tower blowdown treatment.
Ultrafiltration (UF) Plants
The Gold Standard for Disinfection
Our UF plants utilize hollow-fiber membranes to provide a physical barrier against pathogens and organic pollutants without removing essential minerals.
• Pore Size: $0.01$ to $0.1$ microns.
• Best For: Removal of viruses, colloids, and silt.
• The Keshav Advantage: We design UF systems that act as an ideal pre-treatment for Reverse Osmosis, significantly increasing the life of your RO membranes.
Nanofiltration (NF) Plants
The Membrane Softener
Often called “Loose RO,” Nanofiltration is the bridge between UF and RO. It is highly effective at removing divalent ions (like Calcium and Magnesium) while allowing some monovalent ions to pass through.
• Pore Size: $0.001$ to $0.01$ microns.
• Best For: Water softening, color removal, and pesticide elimination.
• Application: Textile industries, pharmaceutical processing, and high-end mineral water plants where specific mineral retention is required.
Technical Comparison: Which Plant Do You Need?
Technology Particle Size Removed Primary Target Pressure Required
MF (Micro) $0.1 \mu m – 10 \mu m$ Silt, Sand, Bacteria Low
UF (Ultra) $0.01 \mu m – 0.1 \mu m$ Viruses, Colloids Medium-Low
NF (Nano) $0.001 \mu m$ Hardness, Color, Organics Medium-High
Why Choose Keshav Chemicals & Engineering?
Based in Jaipur, we combine chemical expertise with high-end engineering to deliver plants that are:
