How to Effectively Clean RO Units

The purpose of this webinar is to provide attendees with some knowledge to effectively clean RO units.
Following a standard cleaning procedure from a membrane manufacturer, a chemical vendor and/or an Original Equipment Manufacturer (OEM) will only work for certain foulants or scalants when initiated at an early stage. Waiting too long to clean will frequently lead to cleanings that have less and less effectiveness over time.

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

[@SVYAKU]

Thanks, the best video on cleaning RO membranes I found

[@herjikdimaano8892]

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..

[@herjikdimaano8892]

While chemical cleaning make sure that water pass on product or permeate line u can adjust it in reject valve,coz some of membranes are hard scaling and water not pass in product line,.u can adjust it in reject valve.

Question 2. Use sodium meta bisulphite to neutralize chlorine before going to RO.. never let chlorine pass through membrane.

MARIANO CAYABYAB maalam aq sir mg chemical cleaning. Hire nyo po aq.

[@xqh_0pq98]

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.

[@samsungblack4027]
