Expanding 250 RO
I am expanding my 2 membrane 4x40 RO to 4 membrane. Plan to try running all 4 in series, the 1st 2 are in series. While I realize I won't double the permeate removal I hope to gain at least 50% removal. I've had a spare set of 4x40 membranes for several years and I recently bought 2 300 PSI 4x40 vessels is SS. My rig is a Ray Gingerich converted to electric. Those who have made their own, what do they call the parts to mount the vessel? One is a cradle of sorts and then a SS band circles the vessel and the band has a T head bolt on each end which is tightened around the vessel and it clamps the vessel to the cradel and the steel frame behind it. I see pictures of these but have not found a listing to buy them. Please advise.
'm expecting it to remove more permeat so I can go higher than 2% to 8% in one pass. I plan to first try the same pump and it will thus still be a 250 GPH but I am hoping to get to 11-12% on a single pass, still running at about 275 PSI.

Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
