Subject Control of metal oxide fouling in reverse osmosis Date 30 JUN 2008
High levels of iron and manganese, along with large quantities of dissolved gases in the wells
created concern for the viability of a conventional desalination design for the proposed City of Camarillo groundwater desalination facility. To identify viable pre-treatment process(es) for the control of metal oxide fouling in reverse osmosis, a 12-month pilot study was undertaken. The pilot study tested several pre-treatment alternatives, one of which was chlorine dioxide and filtration using dual media filters to remove both iron and manganese oxides.
