Does it matter where permeate comes out?

[cjf12]

I am adding 2 more 4x40 post. Concentrate goes in bottom of #1, out top. In top of #2, out bottom. In bottom of #3 and out top.
My question is can I have all the permeates exit the top? It would be a little easier to plumb that way.

Tees on top for permeate.
90s lower against membrane cap are for concentrate.

If plumbed properly they should all come out of the top. I have a 2 post setup and I connect both to a T and then 1 hose goes into my permeate tank.

My way of thinking is that the sap or concentrate should all gpo in one end and the permeate out the opposite just for a better flush when you clean. Asside from that it should not matter.

I added a 4x40 to my single 4x40, and both permeate lines come out the bottom, although the concentrate comes out the bottom of the first vessel and INto the bottom of the second. I'm adding two more for next year, and I'm going to orient the vessels horizontal. The brine seal needs to be opposite the concentrate/sap entry, and it's a bear to unload the membrane on my second vessel the way it is now. upgrading from 1 1/2hp PC 300 t either a 3 hp 660 or a goulds, still pump shopping s of now. I just odered two new vessels, 300psi, SS, 3/4" feed ports, $79/free shipping on Amazon, and they come with mounting hardware. https://www.amazon.com/gp/product/B07N3XTRZS/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I got those same vessels. Running a 330 procon and upgrading to a 2hp motor. Hope that will run 3.

I ran two vessels with a procon 330 and a two hour motor. It worked so well I couldn’t believe it. I didn’t use a recirculating line, I just ran it back into the tank to concentrate it. It easily went up to 9 %. But it does layer. I could take sap off the top at 3% and out of the hose off the bottom at 8%. So I’m thinking about adding that for next year. I ran it at 200 psi fearing such high pressures. I noticed the second vessel was somewhat fouled at the end of the season. I’m having them professionally cleaned now so I can start fresh next season. I’m going to have to figure out flows. It is a bit of a mystery to me

The higher the pressure (as long as the vessels and hoses are made for that pressure) the better the water removal and the increased concentrate flow which helps keep the membrane cleaner.
