Deionized Water for window cleaning applications
Professional window cleaners in utilizing deionized water are very fortunate that Portland Oregon has great water. Deionized water tanks contain mixed bed resin, which turns tap water into pure water. Resin will last at varied rates depending on the level of your totally dissolved solids (TDS). Window cleaners in Portland using deionized water, are able to monitor the deionized water quality with a TDS meter. When using Deionized water for window cleaning, you want to be sure that your water is completely pure and reads “000″ on the meter. This will ensure that it is impossible for the deionized water to leave spots on the glass.
The cost of a deionized water system
If you have a hard water in your area, or tap water measuring over 100 on a TDS meter, a deionized water tank may not be the most efficient option. RO /DI or reverse osmosis followed by using a DI system are more cost effective, fairly compact, and can be installed inside a vehicle. Your water pressure and working height may require you to purchase a booster pump to make the RO system work efficiently. It is imperative that you change the filters as well as the membranes at the top of your RO system regularly. Proper maintenance and care of your system will ensure clean windows for the residential and commercial window cleaner. Complete RO/DI systems can be purchased for around $3500, or if you are the adventurous type you can build one for less. My thoughts on pure water are: it is better if you need the full kit to just purchase one fully ready to go.
Can I just us a deionized water tank
When you are shopping for water storage tanks for your window cleaning business, you can purchase deionized water from a number of different sources. If you are looking to rent a deionized water tank Siemens offers a variety of tanks to suite your needs. If you are looking to purchase a tank, large farms may have used tanks, as well as some do-it-yourself stores. If you are using your tanks for commercial window cleaning, you may need to purchase a larger tank. For residential window cleaning, a smaller tank may be enough. Deionized water tanks can be purchased online or from a local supplier at reasonable costs. If you purchase the tank you will need to buy a mixed bag of DI resin to replenish the system once the filter cannot sustain “000″ on the TDS meter. Anything above 5-10PPM and you will see spots on the glass. Another option is to rent a deionized water tank if you can find a local supplier.
