question about r/o pre filters

[koicrazy2011]

Hi Im new to ro I have researched but unable to find the answer.Im running a 5 stage 150gpd r/0 system with one sediment and two charcoals.Now Im running well water with no chlorine or chloramine but I have a ton of sediment.I wanted to know if I could or should change out one of the charcoal blocks to a extra sediment filter so maybe have a 10 micron first and then go to a 5 or 1 micron.I didnt know if this will work or if it will increase my water productions.Im also running the aquafx booster pump and Ive taken out my di because I noticed more water and no tds spike without it.

Again thanx for taking the time for a newbie


Peace:wavehand:

If there isn't any chlorine in your water then two sediments and one carbon sounds like a good plan. I would still keep the DI stage though. It doesn't add much pressure and shouldn't affect the output that much.

Good idea. You might also want to arrange your system so that at least one sediment filter (the most coarse) is in-line before your booster pump.

ok cool thanx

I have the pump mounted right before the first sediment filter kind of right next to it pressurizing the water right before it. Is that correctly installed? I also found that I could upgrade to a 400gpd membrane would this be able to substantially increase my water production over my 150 seeing that I get about 120lbs of pressure after the booster pump?


Thanx for you input and time sir


Peace

With that much sediment I would pre-filter (10 micron) before the booster pump then a 1 micron before the membrane. Personally I use a 1 micron then a .5 micron on my own sytem.

Like aquainas said... the idea of putting it before the booster pump is to protect the pump from sediment. You can place a second after to further protect the membranes. I could be wrong but I thought the idea pressure for membranes was about 80psi. 120psi seems high. Also, you can't simply replace your membranes with a larger capacity membrane and get higher output. Your system includes a flow restrictor that is matched to your membrane.

I have a similar system, but I am using city water so my system goes 5m Sediment, booster pump, 1m sediment, 5m carbon, 1m carbon, RO, DI.

It is recommended that a 100m Sediment run before a booster pump if I remember correctly, so my 5m is more then enough. I hope this helps.

Couple of points:

The best place for the booster is AFTER all prefilters - this way you don't expose the prefilter housings to the added pressure.

We typically recommend a strainer after the carbon block but before the pump. Less expensive than adding another housing and poly sediment filter after the carbon.

Your residential scale booster pump can't handle a 400 gpd membrane Aquatec 8800 booster pumps for instance can handle membranes up to 120 gpd.

What is your current waste water to purified water ratio?
