Ultrafiltration membrane system or ultrafiltration water purification plant is pressure-driven process, it removes particles, suspended or particulate matter from water. The ultrafiltration membrane system can be used most effectively instead of pretreatment unit like sand, activated carbon mechanical filtration.
UF membrane permeability is more than reverse osmosis membranes. The most important things about Ultrafiltration water purification plant, if you use just Ultrafiltration membrane system, your raw water TDS can not be removed using MF and UF due to lower size.
UF with a nominal pore size of around 0.02 μm is found to be the most effective in eliminating potential elements such as microorganisms, silt, algae, and large molecular weight from the feed water source that are responsible for RO membrane fouling. Most of the application ultrafiltration water purification plants are used as pretreatment for RO system.
Ultrafiltration membrane system fall between that of nanofiltration and microfiltration with a pore size range between 10 to 100 nm, or about 500 to 500,000 Dalton in molecular weight. UF membranes typically operate between 3 – 5 bar, of course, in some special cases to 8 bar and are dependent on trans membrane pressure to drive the separation process. You can see seperation size and molecular for Ultrafiltration Water Purification Plant from below table. If your water TDS is very low and clean, and you want to keep important minerals for drinking water UF mineral water filtration is suitable for you.
UF processes are currently preferred over traditional treatment methods for the following reasons:
1. No chemicals are required (aside from cleaning)
2. Constant product quality regardless of feed quality
3. Compact plant size
4. Capable of exceeding regulatory standards of water quality, achieving 90–100% pathogen removal
UF Mineral water filtration is becoming popular in drinking water industry. Because UF mineral water filtration systems keep water’s valuable minerals but remove big particles, bacteria and microorganism. Especially some famous drinking water companies to keep water taste and nature, they are using mountain water as raw water source and use uf mineral water filtration equipment.
To kill bacteria, virus and other microorganism we can add UV Sterilizer, ozone generator to your uf mineral water filtration machine.
