The stringent regulatory requirements for recycled water proponents are in

In order to protect public health, validation and monitoring of RO process integrity are necessary to ensure its correct operation. To-date, there is no national or international accepted validation protocol for RO, despite conventional techniques such as conductivity, TOC or sulfate rejection having been used for this KX2-391 purpose. At present, each proposed protocol still requires review and approval by relevant regulators on a case by case basis (AWRCoE, 2014). An agreed validation protocol establishing a correlation between LRV and indirect continuous online monitoring would provide confidence to recycled water treatment plant operators and project developers. In image particular the ability to accredit LRV of three and above could reduce the investment costs and simplify treatment process trains by removing potentially unnecessary additional barriers. It has to be noted implantation the validation of a specific process might be limited by regulation. For example, the state of Victoria (Australia) (VDoH, 2013), limits the validation of a process to 4 LRV in order to force the use of multiple-barrier systems reducing the risk of outbreak in case of a process failure.
