Rodi booster question

[Fishingandreefing]

All, I got an aquatic life 100gpd rodi and it takes about 1.45 hours to produce a bucket of rodi.

with my second tank on the way and I like to change water weekly, roughly 30g per week, is the booster worth it?

I connected my rodi unit in a restroom and if I measure the outside faucet, is that an accurate reading?

I can’t comment on that booster, but booster pumps make a massive difference

I only installed one when I build my new ssytem recently and I couldn't believe the difference in water production

Got you but what about on checking the psi? Outside faucet good to go?

 

[Jaebster]

Yes, outside faucet is good.

A booster pump will increase production, however depending on what water pressures you can naturally obtain you may not need one. Most RODI systems have ideal pressure parameters that are typically above 50psi so if you can’t obtain that naturally you want to install one.

My house water pressure is jacked easily and I can easily run 80 to 100 psi through our RODI. As a result we produce water pretty fast. If you produce a bucket...in 1.5 hours roughly... and that bucket is a 5g bucket you’ll need about 9 Hours for 30 gallons. Reasonable for 100 gallon per day and can be improved a little for sure but you can’t, or shouldn’t try to double that production with that membrane as the pressures would be too high.

That make sense. Prob just leave it.

I used that booster pump on a 180 spectrapure system and it toasted the membranes. The flow restrictor is 300 ML and that is not sufficient for that much water. The pump i believe is rated for 50 GPD or so. They had a method for me to bypass the flow restrictor using my 180 flow restrictor and a check valve and wye fitting. I now use an Aquatec pump with pressure switch

Good to know! I guess I am good, about 1.5 hr per bucket by the 4 stage aquaticlife 100gpd

I have the BRS water saver kit, which doubles production and with 78psi I get 5 gallons in about 45 minutes. Would recommend getting the kit, it feeds waste water from 1st membrane into second membrane and combines the output from both.

Looks like it only works on BRS rodi unit but mine is the aquaticlife.

I have a Coralife, it works great.

Just to clarify I have the twist in 100gpd unit, is that what you have?

 

[Phil D.]

nope, now I know what you have.

You can add another membrane to just about any setup. If this is the 4 stage 100 GPD aquaticlife with 10" housings and brakcet, you should easily be able to add clips, a membrane housing, some tubing and fittings and another matching membrane with a proper size flow restrictor. At that point though, the smart buddie pump may not be compatible with the GPD of the dual membranes. My membranes rejection percentage went from 99% to 94% within a few days with the 180 and smart buddie. I have hard water and it basically ran my unit at 1:1 until i went with their work around.
