Single XLE 4040 Build

[Flat Lander Sugaring]

Could you elaborate a bit on this? I have the same membrane and housing as mentioned. What should I look for and/or what is needed to adapt the membrane to the housing? Surprised Joe didn't mention this to me while talking to him about my purpose for purchasing the membrane. Anyone have a picture of a membrane that is female or "cut" vs a membrane that is not?

Thanks!

if u you bought both things from joe you need no adapter. I just received two XLE from him and all I told him i had stainless 4" housings. His membrANE DROPPED RIGHT IN ( dam caps lock). There are adapters out there but if you have stainless housing like us no need to worry.
He is in on Saturdays so any questions call him

Thanks. That puts my mind at ease. Suppose I should get the plumbing done on it tomorrow and wrap up this build!

Stoweski,

Looks like you got your question answered.

Best.

Thanks to everyone for all the great info on this topic. I'm in the works of ordering the components to build the same (or very similar) RO. I started out with an RO built with residential membranes (got the info to build it here) and it worked good but just too slow and not enough capacity. Could someone explain how to setup and plumb for recirculating? What other components do you need and how do you control how much concentrate is recirculated? Would love to see some pics of the finished product too!

This is my "vintage" Sap Brother. To create a recirc loop you have to tee into the input side of the hp pump. And you have to tee into the output concentrate line from the membrane. Then you place a valve (or valves) between those two points. I have two valves in my case. A main ball valve that stays closed when rinsing/washing. Then it's opened fully for recirc. In line with the ball valve is a Parker(needle) valve that is adjusted to achieve the desired concentrate level by reading the flow meters.

A - Input to hp pump
B - Output to membrane
C - Concentrate from membrane
D - Concentrate to Concentrate valve , flow meter, and out to feed tank
E - To main pressure gauge(dead end)
F - Main recirc valve
G - Fine tune needle valve for recirc

Hope that helps.

Thanks so much for the info and pic. Great to see how it is actually plumbed. Really quite simple when you see it. I will definitely incorporate this. Thanks TunbridgeDave

Just curious...would my aquatech 8852 work as a feed pump or would its flow rate be too low?

No, Your aquatech will pump 41gph and the recommended pump for the XLE 4040 is a 265gph pump.

Hello everyone, just bringing this back up to the top for some advice before I start this build. Just checking to see if there is anything different going on in the RO world. Still planning on going with the single XLE-4040 membrane. Anybody with a similar setup feel free to chime in with what you would do differently next time or mistakes you made.

Thanks,
Matthew

According to other posts, Joe at Atlantic RO has passed. You'll need another sounding board there. Not a problem to wait a year before build, many have done that. If you're expanding a bit, why not just buy a small purpose built RO and take a pass on the potential mistakes? Say, a Deer Run 125, either electric or gas? I built a small RO, it worked and works, liked building it, etc... but I prefer the Deer Run one, its well built and functions great. Look, this may rile you, but its not intended to, so sorry if it does.
Good luck with your build if you do it. I'd like to see pics if you're able to post them from your build. There are trends in manufacturing maple ROs, I'd contact all the big manufacturers and MES to get some good info there.
take care, Mark
