iron & manganese with membranes
iron & manganese with membranes
(OP)
I posted this is chemical engineering under membranes with no response so maybe someone here has worked with this.
Just curious; but, has anyone had any dealings good or bad with using membrane technology to filter iron/manganese from potable water applications?
I've done many plants using conventional methods (aeration/sedimentation/filtration, oxidation/greensand, aeration/flocculation/filtration, etc.); but, have only seen membrane technology for this process as illustrated by a couple membrane providers.
The iron/manganese after oxidation forms a floc that is light and sticky. It seems to me that this will have a detrimental affect on the membrane, causing it to foul early.

RE: iron & manganese with membranes
Some of the membranes will require pretreatment. The pretreatment (multi-media)will probably take out the iron.
RE: iron & manganese with membranes
But, I've read some articles on using membranes for iron removal and they've recommended no aeration prior to the membrane. That is the only way I can visualize them working without fouling at a high rate.
Thanks for your input. We're just now having the opportunity to use membranes as we have a well with high radium counts.
