The whole concept behind pure water cleaning is that you can use any water, run it through the pure water cleaning system and make it 99.9% pure. And, while that is how it works, there is a little more to it.
First and foremost, it helps to know what the TDS (total dissolved solids) of the water is before you start. Some areas of the country have “city water”, or water that is run through the municipal water treatment plant. The average TDS for this type of water supply is fairly low and even a simple dionization system can clean it up easily.
Further out, in more rural areas, you may encounter more well water, which generally has a higher level of TDS. It’s not dirtier water, per se, just less processed. Depending on the reading, the size of the job and your pure water system, you could potentially blow through almost an entire DI tank in one day. This would be a situation where a 4 or 5 stage reverse osmosis system would be a better choice. The DI tanks work in unison with the RO membrane to remove the impurities and leave the water at an acceptable reading.
Another concern is the desert Southwest. The water is pretty bad and TDS readings can reach into the 500 range.
We’ve seen a lot of window cleaners posting questions about TDS readings in other areas. Sometimes they need to know for a job, sometimes its just general curiosity. Then, a FaceBook friend posted a link to this site, which we thought was pretty cool. It’s geared towards drinking water, but we thought it was pretty cool that you can look up TDS readings across the country. heck, you can even upload your own.
If you have any questions about how simple, safe and cost-effective pure water cleaning is, give the office a call and we can tell you all the amazing details.
