RO System

[Buckeye Hydro]

Reject water recycling is doable if:

• your RO system is plumbed for it
• your RO system has a reject water flow gauge
• you've done a water quality lab analysis of your water, and run the results through modeling software to make sure you don't recycle too much.

Why would you want to recycle some of your reject water? To save on total water use and save some $ on your water bill and wear/tear on your prefilter equipment.

So if recycling a little water is good, is recycling more water better? Generally not - as you can recycle too much water and toast your RO membrane(s).

• your RO system is plumbed for it

You can replumb any RO system to recirculate a portion of the reject back to the pump.

A flow gauge is handy but NOT necessary.

Totally unnecessary for car washing.

Yes - that replumbing can be done, obviously, but in our experience many are not interested in doing that, for several reasons.

It's like saying a gas gauge is not necessary in a car. Technically that's true, but if you want to optimize the life span of the RO membrane(s) you don't want to go beyond a point in the amount that you recycle that you'll get deposition (plugging) on the membrane, nor do you want to recycle too little so that you're not maximizing your water savings.

The lab analysis anyone should do before they invest $1,000's in water treatment equipment will likely suffice for the necessary modeling... probably no need for more testing here. If you work with the right vendor from which you buy your equipment and/or replacement membranes they may do the modeling for you at no cost.
