The alcohol, low oxygen content, relatively low pH, hops extracts (alpha-acids) and dissolved carbon dioxide in beer inhibit the growth of pathogenic bacteria. That is why beer has been a safe drinking alternative for so many centuries. However, there are microorganisms that can survive and even thrive in beer and spoil the flavor and aroma of any good brew.
The goal of pharmaceutical water system operators is to produce bacteria-free water that meets or exceeds required purity standards. Water systems use several filters to protect system components and to assure that the water dispensed for use is free of bacteria and most other particle contaminants.
Keeping Contaminants Out of Water Tanks Most of the time, the old saying, “An ounce of prevention is worth a pound of cure” is true. Preventing an unwanted event is usually easier than doing remediation work to repair whatever damage is done if the event occurs. However, in virtually all water systems, including pharmaceutical water systems, it is safe to assume that BOTH prevention and remediation are needed to control bacteria and other contaminants.
We hear this question on a regular basis, and although some may quip “buy cheaper filters” we contend that installing the RIGHT filter is the key to doing both simultaneously. Our experience with customers in different industries and applications has shown that those who spent the time to assess their process and test alternative filters are the ones that succeeded in finding cost savings and process performance improvement. Since every application has its nuances and every company has their standards, in this article, we will offer a more generic and holistic view of the question;
While filter ratings are an important indication of how well a filter will remove particles of varying sizes from a fluid or gas, it is important to note that nominally rated filters from different manufacturers can have the same rating, but yield different results. The opposite is also true – nominally rated filters from different suppliers can have different ratings, yet yield the same result. Naturally, this can create confusion and impact your filter buying decisions.
