Backwashing Filtration

If you've ever heard the term "backwashing" when it comes to filtration, you may already be familiar with such a thing - but if you want to dive a little deeper, here's a quick breakdown of what it is:

∙ The term "backwashing" in regards to filtration is specifically identifying a water filter that can clean itself, or "regenerate."

∙ "Backwash" is a cycle within the regeneration process in which the flow of water within the filtration tank is reversed, which releases the elements that were filtered out of the water and would otherwise remain in the filtration tank. These elements are released and removed through a drain line that exits the building, and ultimately returns to the earth.

∙ The mechanical valve on top of a backwashing filtration tank is set to regenerate (regen) on a specific time interval, based on water usage and water chemistry.

∙ In general, the regeneration process uses roughly as much water as an average person uses in a day (50-100 gal).

∙ Backwashing filtration requires an electrical outlet (standard 110v) for power supply, adequate water supply, roughly 2-5ft of wall space, room height minimum of 68", and a place to run the drain line (typically to a downspout or septic system).

∙ If you use water while a backwashing filter is in regen (is in the regeneration process), you will introduce contaminants into the plumbing/fixture that you're using (toilet, sink, shower, laundry, etc.).

∙ For this reason, we program backwashing filters to regenerate at a time when water is not typically used (from 1am to 3am in most cases).

Backwashing water filtration is an excellent option for hands-free filtering. In the system pictured above, the two tan "torpedo" looking tanks on the left are backwashing filters. The blue canister filter above the brine tank is not - it does not regenerate and must be changed manually.
