Sterile Filtration for Compressed Air Systems
The need for 100% sterile, bacteria-free compressed air is common to a number of industries as diverse as the applications they serve. Food processing and packaging, aseptic packaging, beverage manufacturing and bottling, brewing, dairy and pharmaceuticals are just a few of the industries that require uncompromising compressed air and gas sterility for their processes. Sterile filters must effectively remove and retain all bacteria and viruses, as well as other organisms and contaminants.
Sterilization filters are extremely fine filters designed to remove microorganisms. The correct application of sterile filters therefore requires prior filtering and purification of the incoming compressed air; air without oil and water, as well as coarse pollutants. As such, it is imperative that the filtration model used uses a stepwise approach. Ideally, you should install sanitary industrial filters, including at least a pre-filter and a coalescing filter, before the final sterile filter. The pre-filter will remove coarse contaminants that would otherwise dramatically reduce the service life of filters installed afterwards. You should install a coalescing filter next in line to remove the oil and water in the system. In addition, an activated carbon filter can be installed after the coalescing filter to remove odors from the air supply. Finally, for typical installations, you place a sterilization filter directly in front of the point of use to avoid infections on the sterile side. Sterile side infection is possible in every pipeline, pipe joint, valve and faucet. The recommended direction of air flow in the filter element is radiation from outside to inside.
Once installed in line, the new unit must be sterilized before use to ensure 100% sterility of the working environment. This is where many applications go wrong, as out-of-the-box sterility is often assumed. There are two recommended methods for sterilizing filters. Almost every application carries the risk of possible increased growth of bacteria on the receiver, and the return of germs through the pipeline into the sterile filter is also possible. As such, you must sterilize each system frequently according to specific conditions. One approach uses hydrogen peroxide, which should not be a problem for the installed filter element. Check with your manufacturer if your filter element can be sterilized in this way. After sterilization using hydrogen peroxide as the active agent, you must drain the H202 deposits from the case before operating the system. Another option for preparing the filter for use involves in-situ steam sterilization. Introduce steam into the sterile filter using the bypass supply line. In this case, use a steam filter to remove coarse contaminants from the compressed steam, thus ensuring a longer life for the sterile filter element. It is important to note that you must re-sterilize your filtration system each time you replace the filter element. It is also recommended that filtration systems be re-sterilized after each shutdown period as bacteria can develop in inactive environments. You should replace the element if your filter reaches the permissible differential pressure of 0.7 bar to 1 bar and if a total steam sterilization cycle of 100 times or 100 hours has been achieved.
The manufacturer should construct their sterile filters with elements made of stainless steel inner and outer support sleeves to withstand surges in the air or gas supply, as well as stainless steel plugs. They should also feature three-dimensional media layering and a 100% binder-free sub-microfiber fabric with 94% voids to support a two-stage depth filtration model. Depth filters should operate at 99.99998% efficiency down to a particle size of 0.01 microns. Media elements should also boast zero migration and zero extraction. Problems can arise when the filter elements contain binding materials, which provide a fertile ground for the reproduction of microorganisms, thus encouraging their growth. Filter elements should also be chemically, biochemically and biologically neutral and inert, as well as resistant to chemicals and high temperatures. Elements should be able to withstand steam or H202 sterilization before use. Properly constructed sterile filters should also have a housing made of stainless steel without cracks to ensure that they can achieve 100% sterile filtration of air and gases.
Performance characteristics to look for in a truly effective sterile filter include:
- Ability to withstand sterilization up to 200°C;
- Steam sterilization cycles up to 100 times or 100 hours;
- Suitability for in situ standard sterilization or reverse flow steam sterilization;
- Guaranteed 100% sterility that can be maintained;
- Resistance to differential pressure of 5 bar;
- Load capacities between 0% to 200% of nominal flow;
- 100% sealing of the element with double 0-ring construction;
- Microfiber filter media without anti-growth binder;
- Finally, both elements and housings must be manufactured with minimum tolerances.
Proper selection, configuration, installation and maintenance are key factors in creating and maintaining a 100% sterile environment for your specific process. You must meet all criteria to ensure consistent sterility. Take care to select the right filters for your system design and create a maintenance plan that will ensure a sustainable sterile environment for your application.
