Cool water-saving item for RO/DI systems

[Steve1714]

I just hooked this up on my RO/DI filter.

Here is what the website says it does;

• Requires no electricity, powered by energy from brine water
• Improves recovery rates by as much as 400%
• Reduces waste water by as much as 80%
• Enhances contaminant rejection
• Ideal for membranes rated from 10-100 GPD
• Effective for inlet water pressure as low as 30 psi
• Increases membrane life, lowers “TDS creep”
• Fills product tank up to 4 times more rapidly

looks like a win win situation to me!
here is a link
to more Info.

Costs about $50 - $65 depending where you buy it.
I got mine through filterdirect.com

It wasn't too difficult to install, does get a little confusing but they sent a great diagram on how everything hooks into it.
Makes a little noise but my RO/DI is located in my garage so the it doesn't bother me much, I saw a quieter model but it is only rated up to 50gal per day systems.



that is just cool engineering

"In other words, if your current system requires 10 gallons of tap water to produce a gallon of pure water (10:1), adding a Permeate Pump should reduce this ratio below 3:1."


i thought we were getting 3 to 1 with our RODI units...

I bought one of these about 4yrs ago from airwaterice when I bought a rodi system from them. I've been very happy with it. It has worked well on my system. I just bought another system from them for a new tank and this new one will fill a plastic storage barrel (i.e., no back pressure like with a pressurized storage tank) and they told me it wasn't worthwhile for my new system. But I guess it depends on the amount of preasure to begin with and the type of setup and storage tank.

Steve,
I always heard that they don't do much if you already have sufficient pressure going into the RO membrane. What is your pressure going in.

Greg;
I have a pressure regulator on my house and it is set to 60PSI. I don't know if this device would be of much benefit to those that do not use a pressurized storage tank (like the one at the bottom of the picture on the right). I am going to split of the line from my FW reservoir, for the reef tank, to hook up to my ice maker on the fridge. I'm tired of my reef system getting all the good water and me having to settle for hauling up 5gal jugs for drinking.
