The process of water ultrafiltration

The process of purifying water entails different stages before it is channeled to a water filling machine for packaging. One of them includes ultrafiltration where the separation of solutes and suspended solids is done through a semi-permeable membrane through forces like concentration gradient and pressure.  In the modern day, this process is done through an ultrafiltration system that incorporates hollow fiber and other filtration technology. Filtration I many cases involve the use of active carbon filters, quartz sand filters, precision filters, and finally hollow filtration.

In ultrafiltration, contaminants such as bacteria, colloid, rust and other toxic substance that is in raw water are filtered out. However, important elements such as minerals present are normally kept. This ultrafiltration process in normally incorporated in the purification of mineral or spring water companies before a water filling machine packages it for distribution.

During the process ultrafiltration, clean water under pressure flows through the hollow membrane whereas large particles are retained. This process is usually dynamic as separation is accomplished through a flowing state.

There are different kinds of bottled water in the market. These include:

  •    Mineral water
  •    Purified water
  •    Spring water
  •    Seltzer water
  •    Sparkling water

What is mineral water?

Mineral water is essentially water that contains minerals and other dissolved elements like magnesium, calcium, potassium, silica, sodium and some bi-carbonates. These minerals are usually healthy and have no side effects.

As a water bottling plant, you should design and customize to meet the flow rate and the prevailing water condition. As much as it removes large particles, the ultrafiltration process should also remove color, odor and some organism such as bacteria.

The UF membrane is normally configured in such a way that it operates as a molecular sieve to produce mineral water. The ultrafilter is thin, permeable, tough membrane that can retain macromolecules such as colloids as well as pyrogens and micro-organisms. When buying a filtration machine, take into consideration the corrosion, temperature, vibration, and pressure. For instance, if your water has high TDS, then you should go for a fiberglass filter.

Advantages of Ultrafiltration

  •    Ultrafiltration process removes almost all particles including the colloids, pyrogens, and micro-organisms.
  •    Minerals such as sodium, calcium, magnesium, and potassium remain in the water
  •    It uses the least amount of energy to produce highly purified water
  •    You can incorporate other treatment equipment depending on the nature of your raw water
