FYI for all the people w/ RO system at home (1 Viewer)

This is for all the people w/ RO water system. I have used this Permeate Pump for over 5 years and this product really works! Here's the link -->http://www.aquariumwaterfilters.com/RODI/reverse_osmosis_membranes.html

I just changed my membrane b/c my TDS meter read 4. That's after 5 years. I change my carbon and pre filters about once a year. I'm not affiliated w/ AquaFX. I just wanted to share this info w/ everyone. I think we all could save some money by extending our RO filter life. Plus you can fill your water 5 times faster and save over 400% of waste water.

How does this work? Although my water bill is basically fixed, I would like to conserve as much water as possible, and the RO/DI is a very large waste.....

I need some better idea of how this thing hooks in, and what is really "does" though...

Thanks

Looks intriguing, but what does this mean? "Requires no electricity - pump powered by energy from brine normally lost to the drain"

it's maaaagic~!

The pump holds the back pressure from the waste water untill it builds enough pressure then it realease the water. The whole time when it's doing this it's recirculating the waste water back through the membrane therefore you save all that waste water. The RO system is like in outer space b/c of the constant pressure your prefilters, carbon, DI, and RO membrane last alot longer. For example w/o this pump lets say 400 gal passed through your filters. B/c of this permeate pump you can have same amount of RO water created with only 10 gallons of water passing through all your filters. 400 compare to about 10 gal. is why you save filters and water. Look just download the pdf file or call them if you have any technical questions. This stuff really works. I wated to share this info b/c I know that replacing filters frequently is very expensive.

I have used a Permeate pump since i got my RO/DI a couple years ago and it is great.

It says that it decreases the time it takes to fill your resevior tank. They seem to be referring to pressurized tanks. Will it fill an unpressurized resevior any faster?
Also, how can recycling dirty water through your RO make it last longer?

RO/DI is designed to remove certain ions out of your tap water and exuding them out through the waste water. I don't think recirculating the waste water through the filters will create good water. Too tired to get into the chemistry of it, but I would not trust it unless I got a lab test of the filtered water.

As I understand it, it will not have any benefits for filling an unpressurized tank. I think it works by decreasing the backpressure caused by filling a pressurized tank.

It doesent recycle that much water.. you still get alot of waste but it produces water faster and my TDS meter never reads over 2 and my filters arnt exactly new.

I thought about getting a permeate pump from Spectrapure many years ago... I asked them about the principle behind it and it was something along these lines:

1) The R/O membrane rejects X% of the ions in the tap water. 100-X% goes out the waste line.

2) The a portion of waste water is rerouted back to the input, mixed with some incoming tap, and the membrane again rejects X% of the ions in the now more polluted water.

3) This process is repeated.

I believe that the reason it works is that the membrane is efficient enough to screen much more polluted water than tap.

The reason the membrane lasts longer is that a greater volume of water, polluted or not, is sent to the membrane at higher pressure. This is the principle behind the flush kits you can buy and provides the same benefit.

The reason I didn't buy one was that I'm lazy and was afraid that if I forgot to push the little button on the TDS tester for a while, as the membrane began to fail, a more polluted mess would end up in the tank.

m'kay. That makes more sense Darrell.

Most of Spectrapure's TFC membranes reject around 98%.

Fishrman asked me to comment on this thread - maybe this will help:

The permeate pump is useful only in situations where you are using a pressurized storage tank.

There's not any recirculation of waste water through the RO membrane. It "decreases waste water" by increasing the pressure to the membrane, which inceases the efficiency of the membrane, and therefore ruduces the total amount of water that must be run through an RO system to produce a given amount of permeate.

We carry the pumps if anyone is looking to add one to their system.
