100 gph RO

[tonka]

I will straight up and say for how simple making an RO looks, I am totally clueless to all the parts(size of everything) in order to make everything function correct. I would very much like to make a 100 gph RO. If there is anyone out there who would be willing to take the time to make a list of all the parts needed to make this build happen would be GREATLY appreciated!! It would be nice to get it made yet this season before the trees really run. I know it is easier said then done.

here are some ideas

AtlanticRO.com
1) 2 4x40 xle membrane
2) 2 4x40 stainless steel vessel
3) 3/4 HP 1750 RPM carbonator Motor 56c frame
4) Procon Pump (Ask joe for for details)
5) lovejoy connection
6) 56c frame adaptor from motor to Pump
7) 3/4 whole house water filter housing
8) a box of 5 micron filters

USplastics.com
1) 1/2 Jaco Kynar fittings for nylon high pressure Hose (6 or more) 1/2 NPT to compression
2) roll of high pressure nylon hose for kynar fittings i think nylon type t ( largest diameter possible 1/2 or so)

directmaterial.com
1) high pressure gauges
A) 1 x 300 psi liquid filled gauge
B) 2 x 150 or so liquid filled gauges
2 ) 2 x 1/2 stainless steel high pressure needle valves
3) 2 or more 1/2 inch stainless ball valves

BuyFittingsonline.com

various pipe fittings such as

1) SS pipe fittings
A) verious size nipples 1/2 x 8 7 6 5 4 3 inch
B) several 1/2 tees
C) several street 90s
D) several 90s
E) 2 x 3/4 to 1/2 bushings

i dont know where (freshwatersystems.com)?
1) 2 x 1/2 flow meters 0 to 5 or more gallons a minute
2) feed pump to provide at least 20psi to procon pump

and a rig to mount all this to.

i would make a drawing before you order to understand were the parts go so you dont order more then needed.
other traders may have better ideas and or cheaper places for parts.

Thanks you SOOOOOO much soft maple for taking the time to list everything off and where to get the supplies, I really do appreciate you taking the time to do all that!! Thanks again!! Will try and get it all drawn up here today/tonight and go from there.

Think will need at least 2 membranes to get 100 GPH!

One XLE 4040 membrane should do around 90gph and remove 50% of the water. So that would give you 45gph of concentrate.

This thread interests me because I'd like to see if I could build an RO system for my setup. I was originally thinking about a system that could process a days worth of sap over night and I would boil the next day but it sounds like with the higher concentration of sugar that while I could do that, I should look at a more real-time type setup. For me that means something that can produce 40-50gph of concentrate which it sounds like this setup would do.

I took a look at the list of parts that softmaple was kind enough to put together and based on that I've created spreadsheet of all the different parts I'll need but there still are a few gaps so I'm hoping that some fellow traders can help me out.

He mentions a 3/4HP motor and a Procon pump but doesn't specify which one or give a spec. One change that I will be making is following nymapleguy's suggestion that one XLE 4040 filter should produce about 45gph so I only need a pump for one membrane. What suggestions would folks have for a proper pump for that membrane? The motor and some of the pumps and connectors that I'm seeing could cost $500 and that seems a little high to me for one membrane.

The parts list also mentions a feed pump and I'm not sure what was meant by that. Wouldn't the pump that is supplying sap to the membrane pump the sap?

Also, could someone put together a diagram showing where all the parts go? I'm not sure where all the tubing, nipples, meters and connectors go. I get the basic concept but a diagram might help me.

My plan is to order all the parts and then have a local welding shop make a frame for me to mount everything. Outside of bringing the rest of my taps online with vacuum again, this will be my big project for next season. I'd like to keep the costs as low as possible though.

Thanks!

i have 2 4x40 membranes in series. they are a nf 90 and an xle. at 200psi I am driving off 1.4 gallons of water a minute. the procon pump is a series 5 ss at 330gph with no bypass. so I can process 400 gallons in 7 hours on my 2x4 vermonter. the feed pump can be any pump as long at it produces 20psi to the procon pump. my pump is a water pressure booster pump for a house. dave, stop by and I can show you how its made and why I modified it the way I did

Nice ,do you have any better pics of this unit and what the parts list is ? a plumping layout maybe -- Thanks

Softmaple; I am interested to know why you used the NF90 and an XLE. The XLE appears to be listed as the best membrane but it also costs less than the NF90.
Which is first in series and why?
When you say you feed with a house booster pump, are you saying a typical well pump like a jet or submersible or something else. Lastly, when you run at 200 psi, is that what you read into the first membrane after throttling the concentrate outlet?
I also would love to see a schematic.
Thanks
