Foulants in Filtration

12/18/2015 9:37 AM

Foulants may be removed from ultrafiltration membranes by use of ultrasound. A solar desalination method has been designed that uses a carbon foam to retain salt but experiences the same cloggingproblem. Could ultrasound be an alternative to avoid clogging fo this paticular case or are there improved processes to avoid fouling ?

Ultrasound may collapse the foam.

This involves study of natural frequency, resonant and harmonics.

Sure anything is possible, but you need to know what is cause the fouling.

Does you chemical rep know what he's doing? The reason why I ask is some don't.... no matter how much education they bring to the table.

The answer is a definite maybe...

Please supply more info on your "carbon Foam"?

There might be another option to avoid the fouling.

Graphene sand has already been used as a concept to do what you are trying.

The foam does not seem to have any major NaCL attractant?

As long as the salt percentage is kept below 7% you would treat fouling in the standard way, via back flushing.

Do you happen to have any links to articles on this topic, it is a bit new. Like any other substrate with flux moving through it, there will be particles stuck on the surface.
