Multi-Media Filters

Some water filtration companies offer a “fix-all” solution for treatment of water by combining a multitude of media in a single tank.  While this is a very effective method for short term treatment, it lacks what we here at try to provide every one of our customers: a long term solution that doesn’t need constant attention.

Most of these multi-media filters will combine some or all of the following: calcite, C, birm and activated carbon.  Birm media is a type of media that has been in use for decades in water treatment, and can be effective in some cases, but is not the standard solution anymore for several reasons.  The actual filtration portion of Birm media is loosely bound to the granular portion, leading to the necessity to replace the media periodically.  New media such as our Terminox media, use a solid core of filtration media that will not wear out or lose efficiency over time.  Birm media also requires a higher pH than many of these new media, which brings us to our next point.

These multi-media filters are often loaded with calcite, corosex or both, which are acid neutralizer media.  These media, when used in a dedicated filter, will typically last 12-36 months, depending on the size of the filter.  Since an assortment of media are loaded into a single tank with multi-media filters, these acid neutralizers will run out much faster, leading to a decrease in efficiency and the need to replace the Birm media sooner.

The last point of concern with these multi-media filters is that they often use granular activated carbon as a polishing agent in a process known as “carbon sprinkling.”  While this act has limited efficiency in helping reduce tastes and odors to the water initially, carbon is the ideal breeding ground for bacteria, so using a filter with carbon on well water, where there’s no chlorination present, can lead to excessive bacteria in the water and can actually be detrimental to the water quality as well as posing potential health risks.

Here at we offer quality advice on treating the water as well as top-of-the-line filtration equipment to ensure that you’re not only satisfied with the water when you first install our equipment, but also for years afterwards.  For a recommendation on the best way to treat your water woes, call one of our expert technicians today at 1-800-684-0979.
