Bioburden Control in Water Systems


Bioburden means microorganisms. In water systems, bioburden can be bacteria, mold or even yeast. You can find specific filters used for bioburden control in the product selection table at the bottom of this page, or read on for more about how filters are used to control bioburden.


Controlling the bioburden level in any water treatment system will improve the quality of the water, prevent the buildup of biofilm and reduce system maintenance costs for disinfection and cleaning. The schematic below shows a complete water treatment system that can deliver multiple grades of water. The bioburden control filters are highlighted.

Bioburden Control

Controlling the bioburden means removing MOST organisms, not all. If your filtration goal is the removal of all organisms, then visit our sterilizing filtration page.

Bioburden control is done using filters similar to those used for sterilizing filtration, but the performance requirements are not as stringent. That does not mean that bioburden control is a secondary consideration. Reducing the bioburden in a system keeps the system cleaner, reduces the cleaning and disinfection frequency and, most important in some systems, protects the expensive sterilizing filters from excessive loading and shortened useful life.

Custom systems are designed for new applications and to solve challenges in existing processes. Critical Process Filtration will work with you to design, build and install a cost-effective system that delivers the results you need. Contact us or visit our custom filtration systems page for more information.

Application Summaries

The choice of filter to use for bioburden reduction is based on the bacteria likely to be found in the system. In general, organisms endemic to the location of the facility (molds, airborne bacteria, etc) will be the targets of bioburden control filtration. Depending on the size of the organisms, membrane filters with 0.65μm, 0.45μm or 0.22μm ratings may be used.

Critical Process Filtration has multiple filter options for removing organisms from a water steam. To read more about the benefits of bioburden reduction and control in your industry, click on one of the links below. Critical Process Filtration has created some short explanations of how removing bacteria from water systems is one step in creating the water quality required in various industries.
