Reverse Osmosis Water

[ron`s]

I wanted to see if any one uses or rents a RO unit for there detailing business. I have been considering using one and would like some feedback. I have used DI water for years. I moved to San Antonio and there is only company here that offers it and it is not cost effective. I can buy RO water in bulk but that is not cost effective in the long run.

Thank You

I don't rent or own any RO equipment yet. I don't know what company is in your area, but I would try U.S. Filter. I almost got a system a few weeks ago from a commercial lab. Then at the last minute U.S. Filter came in and removed it( I guess it was there system).

I would investigate the overall cost of RO systems. I think you'll find as I did that they waste way too much water. That is unless you can find a way to divert that water to a holding container. I have expressed my concern to several companies in the past asking for a remedy. Not one had a clue how to resolve the issue, while admitting that a fair amount of water is wasted down the drain.
YMMV

Mr Clean & OI812
Thanks for the response. Im looking for a small unit to produce 150 to 200gal per day. I know there is waste water involved with these units. Im curently buying 100gal at a time @ .10 per gal. When im back up to full speed with my business I will probably use 100gal per day. This will get expensive and be time consuming.

ron`s,

I will look forward to your findings, and specifically what system you settle on.

IIRC the RO systems I looked at (admittedly this was for home use) rejected @ 3 gallons of water for every gallon of RO water produced. The systems I was considering wouldn't produce 100 gallons per day. Perhaps there are systems now with membranes which are less selective.

Ooops, forgot to add this quote:

Factors To Consider

All of these benefits do not come without concerns. As pure water is generated with RO technology, a concentrate stream is also generated to insure that the membrane does not fail. On one side there is the spot-free water and on the other is the concentrate stream, which is two to four times the volume of its counterpart. Given this additional flow of concentrate water, the end user must consider the option of reusing this resource. If this water is not reused, carwashes can go through an excessive amount of water. Fortunately, in the carwash environment, that water is generally captured and reused to wash vehicles.
