Thanks, the best video on cleaning RO membranes I found

One of the most informative presentation on cleaning RO membranes. Must watch.

Thank you very - very much , sir. This video is very helpful for us .

On my experienced mostly fouling found on first 2 membranes and scaling is on last 2 membranes. But the most effected membranes is on second stage.. in my opinion theres three factor when to make chem cleaning, 1. Conductivity increasing(depend on feed water quality and broken o-ring). 2. D.P. 3. Flowrate(depend on feed water quality.. i want to learn more about water treatment, im from philppines currently working here in qatar..

I have experienced in RO,recycling RO. De-ionized and ultra de ionized system,MBBR,MBR,conventional wwtp...Chemical waste(H2o2)using mmbr we neutralized h2o2 by using sodium sulphite.

Thanks for your very useful information. Compliments from CF Aqua Philippines.

It is considered safe to add hydrochloric acid to citric acid while washing the membranes????

@davidh.paulinc.5874

To Adjust pH yes you can add HCl to citric acid but the pH limits of the membrane manufacturer HAS to be followed. So in other words if the manufacturer has a low pH limit of 2.0 and after adding citric the cleaning solution is at 3.0 pH it would be safe to add enough HCl to lower the pH to 2.0 but not lower than that. Hope this helps.
