Investigation of Hybrid Self Regenerating Ion Exchange- Reverse Osmosis (HSIX-RO) for Low TDS and High TDS (Brackish) Water
Recently in many regions around the world, the available source of water has a phenomenon highly saline and/or high hardness. To provide clean water with a suitable cost, Reverse Osmosis (RO) is among the most reliable technologies, however, the RO membrane is suffered from calcium carbonate and other scales available from feed causing precipitation on the membrane surface. Scaling control in RO membrane was used popular through dose antiscalant and acid. Ion exchange (IX) is one of an efficient and reliable method as a pre-softening process before RO performance. However, the applying of IX softening has had a little limited used due to higher operating and capital costs of the regenerant chemical. At this study, a combination of ion exchange method and reverse osmosis in a system together was proposed. It was called "Hybrid self-regenerating ion exchange RO (HSIX-RO) systems" that use the “free” salt from the RO reject to regenerate the resin without a need to add whichever regenerant chemical. Two operating schemes of HSIX-RO depended on the feed characteristics were proposed and further validated using high hardness with different level of total dissolved solids (TDS). Performance of ion exchange and membrane process were collected.
