Does 'backwashing' flush out the bad contaminants and added chemicals in our water?

It's been great to see more people becoming concerned about the cleanliness of the water in their homes in the past few years. This has caused homeowners to invest in water filtration for their homes so clean water can be readily accessed. The need for education is important regarding this water filtration movement. There's a lot of (mis)information out there about water filtration - so how do we decipher the validity of everything we hear? PuraClean will set you on the right path to pure, clean water with the top misconceptions debunked.



MYTH #4:

If a filter doesn’t backwash, then it has no way to clean itself and flush out the bad chemicals.


FACT:

The biggest misconception is that during a backwash mode, the bad contaminants and added chemicals in our water are flushed out of the filter. This is simply not true. In a carbon filter, the chemicals in the water, such as chlorine and chloramine to treat water are absorbed by carbon. Simply put, activated carbon acts like a sponge with a large surface area and absorbs the contaminants.

They are not flushed out during backwashing, which is why carbon has a shorter lifespan. Once all the carbon media is saturated, the media can no longer absorb the chemicals and must be replaced. What may be even more surprising to many people is that activated carbon is an excellent growth medium for bacteria. The bacteria grows, coating the activated carbon, reducing its effectiveness and introducing bacteria into your drinking water. This is another reason why carbon filters must backwash. Bacteria is generated in all activated carbon beds.

As the bacteria reproduce, they clog the bed, as do the retained solids which is why they must backwash, to eliminate excessive biomass. This is why we use a media called KDF in our whole house filters. KDF inhibits the growth of bacteria and does not require backwashing or discharging any water.

Lastly, I have heard companies recommend using the backwashed water to water plants, so it only goes to prove that the water that is flushed out of carbon filters can’t be full of contaminates; otherwise, you would be unable to use it on plants.

There are a lot of myths out there about your water, but the best news is that there are also a lot of answers.
