Hello, Have a small cleaning business and have been asked by a few customers if i could clean their windows whilst doing their home. As this wouldnt happen often was thinking of back pack or trolley system with DI for ease rather then RO. My TDS is 290, any idea how many litres of water i would get from a bag of resin?

 Cheers

Gardiners have a resin calculator,
If you put in tds290 and foe example 200 ltrs of pure water made, it says it will cost £8 something to make it.

Use D I only is not cost effected over 50tds.You will do better to find someone in your area selling pure water.Ask on this forum if there is someone in your area that could help you out with water at a small fee.
