The use of pyrogen filters in demineralized water treatment (fully demineralized water) makes sense because they remove pyrogens (e.g. endotoxins from bacteria) that can remain in the water even after bacteria have been removed. Here are the main reasons for their use:
- Avoiding contamination in sensitive applications
- In the pharmaceutical industry and medical technology (e.g. dialysis, injection solutions), the water must be pyrogen-free, as endotoxins can trigger fever reactions and inflammation in the body.
- Extremely pure water is also required in semiconductor production or laboratory technology in order to prevent contamination and faulty production.
- Supplement to other treatment processes
- Reverse osmosis (RO) and ion exchangers remove ions, but not always pyrogens.
- Ultrafiltration or special pyrogen filters with pore sizes < 0.02 µm are necessary to effectively remove endotoxins.
- Ensuring water quality after treatment
- Pyrogens can remain in the system even after thorough disinfection.
- Pyrogen filters prevent secondary contamination in the final process stages.
Pyrogen filters are an important component of demineralized water treatment when maximum water purity is required - especially in the pharmaceutical, medical and high-tech industries. They ensure that no dangerous endotoxins remain in the water even after bacteria have been removed.
At HeylNeomeris, we use pyrogen filters in our modular cabinet systems to remove pyrogens from the water. Pyrogens are substances that can trigger an immunological reaction in the body, in particular an increase in body temperature. These filters are particularly important in areas where the absence of pyrogens is crucial, such as outpatient clinics, to ensure optimum water quality for the reprocessing of instruments and medical devices for operations.
The pyrogen filters consist of a filter element with a very fine pore size (typically in the range of 0.1 to 0.2 micrometers) that effectively retains particles and microorganisms. In the modular water treatment plant, this filter is used after other pre-treatment stages such as filtration and disinfection to ensure that the water is purified of all pyrogenic substances.
