Default Homemade RO

Thinking about making a DIY RO set up. Anybody ever build one and does any one have info they could share. Only going to have 60 to 80 taps want to scale the system to that.

With the price of hobby RO's these guys build its probably worth the time saved building your own and just buy one.

I know. I was reading old post on an old thred on RO systems I was just looking for basic ideas. I'm going to gravity feed a booster pump through a sediment filter then into two RO filters hook in series. (Not sure if parallel is better) just wondering flow rates and how much water I could possibly remove with two RO. Filters I know sap temp, sugar % will all effect the out put. Just looking for some tips and thoughts

I don't know about that. The closest size they sell to mine is $2875 plus whatever shipping cost. I have just under $1000 into mine plus the added benefit of knowing how it was built , with what parts , how it works, and also knowing I can expand easily in the future. Of course the future is this year with another membrane being added . :)

I have read the the posts and have done some research all the set ups are great still think they ar all to over sized for me. Only need something to keep up with my little flat pan. And 70 taps. Going to have too experiment. If RO is RO why won't a small system that you would use in a house work?

It would technically work as long as you removed the carbon pre-filter, and any other UV light type options that come with it, as they will be destroyed when sap hits it . You would only want to keep the solids pre-filter (to keep dirt and small crud from hitting the membrane) and the actual ro membrane. The only other issue I see with using a system designed for a home is that those typically meant to be plumbed into an existing water line, where there is already pressurized water. You would need to find a way to pressurize (i.e. pump) your sap through the ro system though.

Check out this video, this guy knows what he's talking about - I dont as much as him.

I have watched that video. I am looking at components on line and just build a simple on I have found a hi pressure pump can operate at 120 to 140 psi. I think that would be the most important part. And instead of keeping the clean water keep what would be the waste water. (Keep some clean water for back wash). I'm going to give it a try any tips or Intel will help. Going to start with two 150 GPD filters. Should I plumb the in series or parallel haven't ever seen a real RO in person.
