Removal of colloidal silica
« on: September 02, 2008, 03:49:45 AM »
Hi!!
I am trying to remove colloidal silica from the effluent sample that I am having. Please note that it is not ionic (reactive) form of silica, nor is it SiO2.
Can somebody suggest some means for doing this?

Tried filtering with a MW cutoff filter?

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Dear Mitch, the quantity I am working with is about 300 cu. metres/day. :( it won't be possible to filter it through a costly membrane, of which the recovery is difficult. I need some economical method to remove the silica.
