What is fouling and scaling on membrane filtration?
Fouling and scaling on membrane filtration are one of the biggest challenges in water treatment industry. Today, I will explain to you how to understand your source water can make fouling or scaling on your membrane filtration and how you can use longer your membranes?
You know, reverse osmosis is pressure driven process, we make pressure on water and force it to pass semi permeable membrane. The fouling of pressure-driven membranes is generally referred to the accumulation, deposition, or adsorption of foulants onto the surface of membrane or within the membrane pores, which can cause the basic membrane functions not work properly such as over filtration time, reducing permeate flow, filtration efficiency, and pressure drop across the membrane.
If you have fouling and scaling problem at your RO Plant, this video is suitable for you. You can watch and understand fouling, scaling on reverse osmosis water treatment system.

We are suggesting you to add CIP (clean in place) system, Chunke CIP systems wash ro membranes in membrane housing automatically.

I have one stage ro system have 24 membranes i changed membranes one months when permate water droped down and presure guages changed also when i tested vessels tds indicated 1 300 2 600 3 400 4 500 and i decided to install new membranes presure guages became normal and vessels tds decreased each one 40 mgl after on 25 days vessels tds increased 400 and i use ants calant geneys LF what is your recommendation please

We shoukd know your raw water analysis report, high pressure pump details, membrane model and pretreatment specifications...Every RO design is different, you did not get any feedback from your supplier?

Which antiscalant is best work to protect Calcium Sulphate scaling?

[@ChunkeWaterTreatment]

Where are you from? If you are in USA, AWC A-101, easily to find. 1-5ppm dosing is enough. But it is better, show your water analysis report to water treatment professional or chemical supplier. Thnx.

[@meryel4765]

what water should be tested to know if there is scaling of membrane ? permeat ? brine ? or feed water ?

[@ChunkeWaterTreatment]

Feed water, first check it with my table in video.

[@bartwz]

​@@ChunkeWaterTreatmentThat's quite a table. Could you possibly point me to where it came from?

[@ChunkeWaterTreatment]

@@bartwz Please see 07:36 , there is a table and we showed the chemical names like CaSO4, SiO2, CaF2...etc. You check your water analysis report, and use method in video, then you can understand your water has scalling problem or not on membrane.

@@ChunkeWaterTreatment Thank you sir, that's very helpful. What I am asking is where the values on that table came from. To be exact what research paper is it based upon. I'm just curious my friend:)
