What is the full form of UF?
The full form of UF is Ultrafiltration. UF is a form of a membrane filtration that is used in the UF water purifiers. Across a semipermeable membrane threaded with hollow fibre, the water is allowed to continue with this method. The huge extracted solutes & particles are maintained, and water moves via the membrane.
Application area of UF
In drinking water preparation or water treatment, UF is highly suitable as a pretreatment. It has extraordinary properties for removing the bacteria & suspended particles. Furthermore, UF is carried out in several industries that are as described below.
- Chemicals sector
- Food sector
- Dairy industry
- Metal industry in the use of oil/water emulsion separation technique
- Pharmaceutical sector
- Textile sector
Benefits of Ultrafiltration
- Usage energy in UF is lower than nano-filtration, or reverse osmosis.
- There are a few Manual Activities requirements.
- It is comparatively inexpensive and not much costly to maintain.
- Alternate high-quality infuse output, based on the water source and the membrane.
- UF allows for the discarding of viruses, phage, colloids and macromolecules to a certain extent. Disinfection happens by killing the bacteria.
- The UF Water Purifiers do not need any energy to function, and the UF Water Filters can continue to perform under regular water pressure from the pipes.
Limitations of Ultrafiltration
- UF discards bacteria and suspended matter.
- UF is susceptible to high concentrations of oxidizing chemicals such as nitric acid, sulphuric acid, peroxide and persulphate.
- By attempting to stop sharp and hard particles larger than 0.1 mm, damage may occur.
- In ultrafiltration, if pressure is higher than 3 bar membrane damage occurs.
