The presence of ferric iron promotes calcium sulfate scaling in reverse osmosis processes
Original language description
Calcium sulphate is one of major components which cause scaling on reverse-osmotic membranes. This may lead to material degradation and to reduction od process efficiency. Several test were held with model solution of calcium sulphate which represented a leachate from poweplant ash-deposit site. This water is in fact a supersaturated solution of CaSO4. This leads to spontaneous crystallization, and thus scaling when this water is treated by reverse osmosis. The leachate also contains small amount of iron ions which showed up to strongly affect the crystallization.
