Controlling scaling in groundwater reverse osmosis : Minimizing antiscalant consumption

Antiscalants are well known for preventing the precipitation of sparingly soluble compounds such as calcium carbonate in reverse osmosis (RO) applications, but it is unclear whether they can also inhibit calcium phosphate scaling. Furthermore, a reliable method to determine the optimum antiscalant dose in RO is currently not available. The main objectives of this study were: i) to optimize the dosing of antiscalants and minimize antiscalant consumption in RO systems, and ii) to investigate the performance of antiscalants in preventing calcium phosphate scaling in RO processes. A dosing algorit... Mehr ...
