UF (Ultrafiltration) in Russia
Ultrafiltration (UF) is a type of membrane filtration process in which water or liquid is passed through a semipermeable membrane with very fine pores under pressure. It is mainly used for separating suspended solids, colloids, bacteria, and large molecular weight substances from water or other solutions, while allowing water and dissolved salts or small molecules to pass through.
UF membranes typically have pore sizes ranging from 0.01 to 0.1 microns, making them highly effective in removing turbidity, microorganisms, and high-molecular impurities without the use of chemicals.
Ultrafiltration is widely applied in water and wastewater treatment, food & beverage processing, pharmaceuticals, biotechnology, and chemical industries. It is often used as a pre-treatment step before reverse osmosis (RO) in water purification systems.
Features of UF (Ultrafiltration):-
- Fine Filtration: Removes suspended solids, colloids, bacteria, viruses (partially), and large organic molecules.
- Membrane Pore Size: Typically, 0.01–0.1 microns, effective for micro-contaminant removal.
- No Chemicals Required: Works mainly on physical separation under pressure.
- Low Operating Pressure: Generally, operates at 1–10 bar, lower than Reverse Osmosis (RO).
- High Recovery & Consistency: Provides stable water quality regardless of feed water changes.
- Compact & Modular Design: Easy to install, scale, and integrate with other systems.
- Durability: UF membranes are resistant to chemical and biological fouling (with proper cleaning).
- Pre-treatment for RO: Commonly used before Reverse Osmosis to reduce membrane fouling and extend RO life.
- Applications: Used in drinking water purification, wastewater recycling, food & beverage processing, pharmaceutical & biotech industries.
