RO is a diffenert process entirely where water is forced through a membrane to remove stuff in the water (ionic and non-ionic). My whole house water system has both cation and anion resins both refreshed with NaCl.
That happens to be the resins he has but you don't have to get that flavor. There are both cation and anion resins available that can be refreshed with NaCl as well as cation resin refreshed with H+ (typically from HCl ie muriatic acid) and anion resin refreshed with OH- (typically from NaOH ie the Lye you mentioned). Most people are familar with water softener resin (a cation resin) refreshed with salt (specifically the Na+ of the salt). Because both resins are used, dissolved possitively charged ions (Ca++ for example) as well as dissolved negatively charged ions (SO4- as an example) are both exchanged for the positive and negative ions provided by the brine solution (Na+ and Cl- in the case of salt). are all just nomenclature for a system that uses both cation resin and anion resin in a single process. If you read that paper I attached above, it discusses both cation ion exchange (which is removing positively charged ions such as is done with water softening) and anion exchange (negatively charged ions). Also, the same sketchy website sells resin for much cheaper as well. I’d guess close to 50% longer life out of a single fill?Īnyway, if any of you guys are using an old CR system, I can’t recommend this enough. I have no way of measuring just how much more efficient my system is now, but I can tell you that it is a considerable improvement.
I’ve been using the conversion for a few months now and can report that I am very happy with it. This kit replaces the cartridges within the CR system with two machined pieces of PVC – essentially increasing the resin capacity and the efficiency in which that resin is used. So, I started doing some research and stumbled upon a conversion kit from a sketchy website called. This made complete sense to me, but I was still having a mental block towards buying over $300 worth of resin and not knowing just how long it would last me. I contacted CR to see if they had any insight and they mentioned that I was mostly likely dealing with resin past its shelf life. At first, I could get through about ten car washes per $20 of resin, but that performance has declined rapidly since 2016. As such, my CR Spotless system has been used quite regularly.įor the most part, the system has performed admirably over the years.
SPOTLESS WATER SYSTEM WINDOWS
We live out in the country, get our water from a well that produces incredibly hard water, and so… a water softener of some kind is absolutely necessary to wash both cars and the windows on our house.
Back in 2016, I reviewed a spotless water system from CR Spotless.
