It sounds interesting. Excuse me for being skeptical as I have never seen a 1 filter RO system.

It has two filters.
One 20" long for chlorine and sediment and then the RO membrane which is a commercial 40" long filter.
It will be on display at the Experience in Dallas. Photos will be available around the same time.
There are a couple of options for the waste water. It can be put on the customers yard or . . .
or since it has no chemicals added, it can discharged to the street.

Benefits of RO/DI:
Zero scale build up
Dramadicly reduced chemical use
Their is also a very odd effect when the carpet dries it has a brightening effect
Fibers are left far softer than you could imagine
It just cleans better!!
Water heats better too
Larry :
What pressure will system run at?
Can you give us a flow diagram?
Based on 380 TDS of city water going in system:
Your system will only need a single yearly filter change ?
What is the replacement cost of your membrane and what do you expect it's life to be?
What TDS should we expect out of the system?
What would be the cost if I want to put the on my truck?

- Does it need a fresh water tank or will it generate enough on demand?
- How much space does it need? Dimensions?
- Assuming the filtration is before cleaning (not after) and that you pre-spray and use a rinse, how can you release it to street? What am I missing here?

Can you give us a flow diagram? April 24th
Based on 380 TDS of city water going in system:
Your system will only need a single yearly filter change ? Our Advanced Carbon Block filter is rated @ 25,000 Gallons
25,000/200 cleaning days = 125 Gal per day. RO should lessen the amt. of water used.
What is the replacement cost of your membrane and what do you expect it's life to be?
We expect 1 year on 40" long commercial sized membrane rated @ 2300 Gal./ day. ($350)
What TDS should we expect out of the system?
Our TDS will vary slightly, but average about 20.
What would be the cost if I want to put the on my truck?
Our system is only designed to to be used with our General pump, and fresh water tank on our Dynachem TM.

Hey Larry
So Can I see your flow diagram???
And what is the cost to install your system on my existing truck (I have a general pump and fresh water tank)???
Will you guarantee only one filter change a year??
Will you guarantee the output TDS of your RO?
Do you have a DI option??
How fine is your sediment prefilter???
How many units do you have running and for how long??
What is the maintenance like on you system?
is the general pump pumping city or RO water?

I can answer that one... No and "Window cleaning grade DI" won't either....
I personally clean with RO/DI and have almost 9 years now. With no degradation to any metals.
I have a system available now thru JRacenstein for Carpet cleaners.

Here you go. Most prefilters today (carbon) use "Radial flow" (more gallons between changes) Flushing of membranes have to be done a minimum of weekly. if not more often.

Everyday is Saturday.
i like the demand pump and all but for that money it makes larrys system look like a deal. plastic housing vs stainless housing?
larrys cost 2000 the one in the link 2200 for plastic?
i do believe larry pre filter is plastic but the main housing is ss. i also like the amount of surface area of the one in the link as it looks like a very large surface areas for the carbon filter.
do you think that ss is of some value vs the plastic?
i am not challenging you, i am asking you as you have experience in using this system? any pros vs cons to the plastic vs the ss?

Not at all....
It is PVC material. It has been the industry standard for many years. Known previously as "RO ultratec". I have been using it over 8 years... The vessel really doesn't make a bit of difference.
Stainless looks nice... But really adds no value to the system. My system does have more surface area of carbon and filtration, put together by a manufacturer with a proven track record.
We are not trying to make it "proprietary" in any way... We would love to sell you media, but you are not bound to us.

And we have it made to be expandable. You add on another membrane, also DI.
Also in 40" vessels

No. besides the idea of my system is not to direct feed your TM, rather use your FW tank as a "buffer" tank.
Personally I use a 35 gallon Buffer tank, and it keeps up. I run a 12 TI.
So you hook up on every job? I carry 170 gallons, so would I have to pre-treat when filling rather then treating the water between my water tank and my TM?
Calling Dave Gill.. How is yours set up again?

Your filters?
As in that is your website? And your design?

Yes, my design. My spec's. No, not my website. That is JRacenstein.com , These are manufactured out of Castle Rock, Co.
I saw a need for a space saving design. And had them made to my spec's.
They are being distributed thru JRacenstein.
I like to be able to produce on location, or anywhere I can hook up for that matter. and it produces a good volume. Far more than any home system.
So a guy that has a large FW tank, can produce at home, or on the site. and not have to go back to his shop to refill.

Maybe this has been discussed and I missed it.
How much water is wasted or used? Is there a ratio?

System design will determine the amount of waste water.
Operating at higher pressure reduces the % of waste water.
Operating at warmer temperatures also reduces the amount of waste water.
(Design for a warm location)
Recycling some of the waste water also cuts down on the amount discarded.
Larry
P.S. Lance, I like your carbon filter design.

Thanks Larry
To add to Larry's response...
The amount of "waste" is determined by 2 things, 1) the source water, and "what" is in it. 2) the amount of restriction of the bypass side of the membrane.
For the most part, industrial membranes, like the ones we are using, are built to minimize "waste". According to manufacturer spec's 5:1
Whenever it is stated a system "produces x amount of usable water, that is based on 77* degree water.
So warm climates really don't have a lot to do with it. It is the "ground water" temps coming in.
I have found (from my experience) a low end limit in temps.
