High capacity RODI?

Are you testing the water with a meter or are you using the color change indication as a tell all?

Ok here's one. I've got a 150 gpd unit (dual 75) laying around b/c the waste water rate is WAY too high presumably b/c my 50psi is split to the membranes. I don't want to put in a permeate pump b/c everything is exposed and b/c I don't want to run an electrical lint to this location. Is there a "simple" plumbing cure? Or am I stuck with 75 gpd or my merlin (which I'm pretty happy with but I AM curious).

Please clarify for me,
Are you talking about a permeate pump or a booster pump?

If it would make things easier for the booster pump they are available in 12 volt configurations.

The permeate pump is actualy non electric.

Oh and what's the most reliable/accurate way to measure TDS (I use those little inline electronic things)

 

[moonpod]

I guess you gotta clarify for me. I don't know the difference between a permeate and booster pump. Which would be better? Again I need something that is nonelectric and doesn't mind exposure to the elements

A permeate pump can only be used in a system with a pressure or bladder tank like used for drinking water systems. It does not require power and can be mounted anywhere the RO is mounted.

I use and prefer a handheld TDS meter. I am not comfortable with an inline monitor unless it has provisions for cleaning, testing and calibration. Its the treatment plant operator in me I guess!

Shoot so for my setup a permeate pump won't work. As I suspected. Thanks

KWL you mentioned having over 2hundred tds?? wow, i'm just over in buford, Gwinnett supply and get 33 tds from tap.

 

[purelyh2o]

WOW!

WOW!

33ppm is actually the rare exception!
Congrats on the great water man!

Culligan must be hurting in your town

I use an in-line TDS. I waste the first 5 minutes or so of initial product water while monitoring the TDS. Once its zero, I flip a switch and run it to my holding tank.

I use the color changing resins to give me a heads-up before I get to the point of my TDS going up.

I am trying to hook up a dual 75 gpd membrane with a permeate pump and a tank - not sure how to do this
