ro booster pump

[rjmurd]

Has anyone tried the aquatec erp 1000 pump? I need a booster pump for my ro since my pressure is only at 35 psi and Im blowing through my di resdin. But cant really afford one. This one is cheap, doesn't use electricity and is a permeate pump.

Thanks for any info

Never tried one, but BRS has DI Resin you can buy and refill the container over and over. This is so much cheaper than buying new DI cartridges all the time.

Not to sound holier than thou or smug or anything like that, but in terms of time spent chasing the issues caused by runaway TDS in your tank and other water quality and livestock issues, it's actually cheaper to take the hit and buy the RO/DI and booster pump, in my opinion, especially if you assign a high dollar value to your own time and sanity.

Short term pain for long term gain. Learn to like Top Ramen, in the interim?

Ive been going through BRS and improving my system.

Ive already replaced the carbon and sediment filters, the membrane and the di resin. Unfortunately, my pressure is too low at 35 psi that its making me go through an entire di resin refill after 70 gallons of rodi water.

So I was looking to bet a booster pump but as cheap as possible cause Im broke.

SO, anyone ever try this pump or know someone who has? Looking for any info.

Thank

I have a good booster pump i just sold my ro . i think it is a 8200 worked great i have about the same pressure,it pushed through a 5 stage 100 gpd across my basment and up to the first floor , let me see how much i can let it go for .

 

[dominic]

yep it is the complete aquatec 8800 set up. with shut off i will do it for $80.00 that is like half price i am in north haven if you want it . Dominic

Just buy an adjustable flow restrictor from Buckeyefield supply BFS-63 put it on your waste water line adjust it until your pressure gets to where you need it. Is the 35psi reading off your R.O. unit gauge???

Just saw this thread. Let's back up a little bit.

The original post asked for information regarding a PERMEATE PUMP. These pumps are useful on systems using a pressurized storage container (like you'd see in a drinking water system). These pumps are not useful if you don't have a pressurized storage tank, and they do not address low feedwater pressure.

The Aquatec 8800 is a BOOSTER PUMP and is what you'd want to increase your low feedwater pressure. There are also some additional items you'll need/want, depending upon your situation, including a transformer, pressure switch, strainer, and solenoid.

We advise against this approach!

If you are using an adjustable flow restrictor, use it to get a 4:1 waste water to purified water ratio, while you ignore the pressure gauge.

Once you get that ratio set, THEN check the pressure. If the pressure is low AT THAT RATIO, then think about a booster pump.

I know this is a thread about low cost solutions, but you can do much better than a 4:1 ratio. If you're going to go inexpensive (or HAVE to go inexpensive) and get a unit with a high waste ratio, you should seriously think about storing the waste and at least use it for watering or gardening or bathing the dog or something.

Thanks everyone for the advice and help. I dont have an adjustable flow restrictor.

I luckily found an aquatect 8800 on ebay that was pretty cheap so i got it. It raised my pressure from 35 to 60. Im not sure about the waste ratio, but its definately prducing alot more ro water.

Thanx Russ

If you have an Aquatec booster pump and are only running at 60 psi, you're not taking full advantage of the pump.

Adjust the pump up to 80 psi if you have it plumbed in before your system, or 90 psi if you have it plumbed in after the prefilters.

If you need a set of instructions for the pump, pm us your email address.

...you can do much better than a 4:1 ratio.

Not sure I follow.

First - remember that what folks call "waste water" really would be better thought of as "flush water" in that this water serves the important purpose of internally flushing the surface of the semi-permeable RO membrane to keep the membrane from fouling/scaling.

Now - if you use a proper flow restrictor you'll have about a 4:1 waste to product ratio.

The recommendation for a ~4:1 ratio comes from the membrane manufacturer. They are telling you that you need about a 4:1 ratio to keep the membrane flushed and keep the membrane from fouling or building up scale prematurely. Run the system with a lower ratio and you will foul/scale the membrane(s) quicker than would have otherwise been the case.

I'm talking about units that have a microcontroller and a flush cycle to clean the membrane. The flush cycle uses much less water to keep the membrane from scaling than a traditional unit that simply dumps a whole lot more water down the drain (or into your waste storage). I've got an AquaFX Octopus that does 1:1 if you discount the tiny amount of water (a gallon or less) used by the flush cycle at the end of every top off of my reservoir.

Granted, a system like that is a lot more expensive and so it's out of the scope of this thread, really. All I was getting at is that it might be a good idea to capture and try to reuse some of the waste from a more traditional RO/DI unit.

In other words, I was just ranting.

 

[rjmurd]

I have it set up after the prefilters because I thought that was where you were supposed to do it. Ill send you my email for the instructions to crank it up. Thanks so much!

Adjust the pump up to 80 psi if you have it plumbed in before your system, or 90 psi if you have it plumbed in after the prefilters.
