Management Technology UF

Holland Water's ultrafiltration technology (UF) purifies water in a sustainable and safe way. Ultrafiltration is a physical separation method in which harmful substances, bacteria, and other particles are mechanically filtered out of the water. This effectively prevents legionella.

Ultrafiltration for worry-free water purification

Ultrafiltration is a membrane filtration process that removes bacteria, including legionella, from water. With ultrafiltration, we offer a reliable and efficient solution for the purification of drinking water, wastewater, and process water, ensuring a clean and safe water installation.

Our ultrafiltration technique uses membranes with a pore size of 0.02 micron. This means that all particles, bacteria, and viruses larger than 0.02 micron are retained, making the filtered water free from harmful organisms and contaminants.

What is it?
  • Advanced ultrafiltration technology for sustainable water purification
  • Filters and purifies drinking water at the point of entry
  • Reduces the risk of legionella colonizing the water installation

Hoe werkt ultrafiltratie?

In ultrafiltration, various suspended particles are filtered out of a liquid using a membrane. In the case of purifying drinking water, harmful substances (such as legionella) are removed from the water with the help of a membrane.

The membrane has a pore size of 0.02 microns. When a liquid passes through this membrane, the membrane captures all substances, particles, or bacteria larger than 0.02 microns. As a result, the water that flows through the membrane is a clean liquid without bacteria or viruses.

Zijn de UF systemen KIWA gecertificeerd?

Absolutely. The UF gatekeepers and filters are equipped with all legal certifications, including BRL K14010/01 for legionella prevention and K14022. 

More about certification

Wat is het verschil tussen legionellapreventie door middel van UV-C of UF?

UV-C is specifically used for disinfection and sterilization due to its powerful ability to kill micro-organisms or stop their growth.

UF is a physical filtration technique in which water is forced through a membrane with very small pores. This membrane can effectively block legionella bacteria and other micro-organisms, preventing them from traveling further through the system.

Both methods can be effective for legionella prevention, depending on the type of water system, the location, and the usage requirements. We are happy to help you make the right choice.

Ultrafiltration with LOG 6 reduction

LOG reduction indicates the extent to which microorganisms such as bacteria, viruses, and other pathogens are removed from water. The term ‘LOG’ refers to a logarithmic scale: for example, a LOG 1 reduction means 90% removal, LOG 2 stands for 99%, and LOG 6 even represents 99.9999%.

Our ultrafiltration solutions use extremely fine membranes that filter out bacteria almost completely from the water. This allows us to achieve up to LOG 6 reduction, which is equivalent to near-complete sterilization of the water. That means: safe and reliable water, free from harmful microorganisms such as legionella.
