Ultrafiltration is a membrane filtration process that removes bacteria, including Legionella, from water. With ultrafiltration, we offer a reliable and efficient solution for purifying drinking water, wastewater, and process water, ensuring a clean and safe water system.
Our ultrafiltration technology uses membranes with a pore size of 0.02 microns. This means that all particles, bacteria, and viruses larger than 0.02 microns are retained, leaving the filtered water free of harmful organisms and contaminants.
Our technology comes in three different applications: Point-of-Use, Decentralized, or Point-of-Entry. All dependent on the challenge you are looking to solve.
Holland Water invites high-caliber providers of building (water) management services – from any country in the world – to become a national or regional distributor of HW watertech systems.
Please have a look at the 'How to become a partner' page and reach out to our Head of Global Sales for more information on how to become an HW Distributor.
Ultrafiltration uses a membrane to filter various suspended particles from a liquid. In the case of drinking water purification, the water is freed from harmful substances (such as Legionella) using a membrane.
The membrane has a pore size of 0.02 microns. When a liquid passes through this membrane, it traps any substances, particles, or bacteria larger than 0.02 microns. This ensures that the water flowing through the membrane is clean and free of bacteria and viruses.
Ultrafiltration is particularly well-suited for situations where a high level of microbiological safety is required, chemical-free water treatment is preferred, stagnation or long pipe runs pose a risk to water quality, and regulatory standards such as BRL K14010/01 or K14022 apply.
Holland Water meets all relevant certifications for its water technology. Whether the technique is allowed in your country or region depends on several factors.
Ultrafiltration is recognized worldwide as an effective drinking water purification technique. There are no countries where UF is explicitly prohibited, but its application depends on local regulations, certification, and context.

LOG reduction indicates the extent to which microorganisms such as bacteria, viruses, and other pathogens are removed from water. The word "LOG" refers to a logarithmic scale: a LOG 1 reduction represents 90% removal, LOG 2 represents 99%, and LOG 6 represents 99.9999%.
Our ultrafiltration solutions utilize extremely fine membranes that almost completely filter bacteria from the water. This allows us to achieve a LOG 6 reduction, which equates to almost complete sterilization of the water. This means safe and reliable water, free from harmful microorganisms such as Legionella.
