Does anyone know the rejection rate of a 4040 RO unit?

Care to explain your set up and how you maintain this 80/20?
Also is that a high pressure or low pressure membrane?
Thank you.

Mine is a high presure membrain when i set mine up they recomended a 50/50 setup as they told me the lower the rejection rate the more sludge you had in the housing.

Are you using a booster pump to produce that 50/50?

the membrian within industry standard is normally set to somewhere between 20-25 % rejection rate
i will allways booster set the 40x40 as they perform better saty cleaner and last longer
