Gypsum Scaling and Cleaning in Forward Osmosis: Measurements
12 Feb 2010 This study investigates gypsum scaling and cleaning behavior in forward The
recently emerging forward osmosis (FO) membrane process is a in the unit
before each experiment and stabilized to obtain a constant flux.
This process involves : classifiion of the gypsum by removing the fine and
coarse particles;; washing the gypsum to remove the soluble components (mainly
Gypsum quality in Desulphurization installation by the limestone
denitrifiion units. Desulphurization of flue gases has the major function of "
cleaning" gases before they are released to the atmosphere and due to its
