XLE 440 membrane

Does anyone have XLE 440's, and what's your opinion on them? 8" membranes

I remembraned our old RO with new xles They worked very well and needed far less pressure to get the same out put tha the old Ms needed.

I did have an issue with sugar passing but after talking with a Dow Tech we discovered I was not allowing enough passage of concentrate for the very high flow across the membranes my unit has. Come to find out I have enough flow for 4 membranes where the unit originally had two membranes.

I cant saw as I have any complaints. If they start to plug I just increase the concentrate flow to flush the membrane for 2-3 minutes and then turn if back down to concentrate.

I will be buying more of these in the future.
