High efficiency reverse osmosis HERO™ process

The high efficiency reverse osmosis (HERO ) process is used for enhanced rejection of silica and boron in SWRO and HPW applications [30]. The process is capable of high rejection of silica, TOC and boron with RO. Further, organic cleaning is minimised at high pH levels, akin to operating the RO unit in a continuous cleaning mode. 

High efficiency reverse osmosis (HERO) is a patented process (US Patent 5925255, Debasish Mukhopadhyay, 1999) originally developed to treat high silica water for the microelectronics industry. Its use has expanded to power and zero liquid discharge applications (see Chapter 15.4.3). Features of the process include ... 

The High Efficiency Reverse Osmosis, or HERO (HERO is a trademark of Debasish Mukhopadhyay) takes advantage of the elevated concentrations of silicates at very high pH (Figure 7.5) and removes metals as part of the HERO process to eliminate the potential for forming metals silicates at high pH on the RO membranes. See Chapter 16.5 for more on the HERO process.
