ROSP stands for linked operation of reverse osmosis (RO) desalination and SAL-PROC™ processes. The integrated process enables the comprehensive use of saline impaired water through combined recovery of fresh water and useful salt minerals and chemical compounds. The linked process can be designed and operated to achieve either zero or regulated discharge outcomes. By applying SAL-PROC™ to the tail end of desalination systems, it is possible to effectively reduce the salt load and volume of RO concentrate, while minimising disposal costs and plant footprint.
There are several options for linking SAL-PROC™ with the desalination process for integrated water and by-products recovery and waste minimisation. For example, SAL-PROC™ may be used for treatment of RO brine or applied for pre-treatment of the feed to RO processes. In the latter case, by selectively removing dissolved species and contaminants, SAL-PROC™ effectively reduces the risk of RO membrane fouling, extends their life and improves the water recovery rate.
