Technology for Difficult to Treat Water
High Efficiency Reverse Osmosis (HERO™) is a reverse osmosis technology specially designed to treat high silica and difficult to treat wastewater. By effectively preventing membrane fouling or scaling, the high efficiency reverse osmosis process offers the end user higher recoveries as well as significant operational benefits. The process has an excellent track record of treatment of cooling tower blowdown where conventional reverse osmosis (RO) is generally considered to be a less effective technology.
In some instances, HERO™ may be used to replace or supplement an evaporation process as a cost-effective method of achieving zero liquid discharge (ZLD). Aquatech has unmatched experience with HERO™ technology with over 60 installations around the world.
Basic process consists of three steps: Hardness and suspended solids removal, Carbon dioxide removal, and RO treatment at elevated pH.

- Lower operating costs
- R2RO Technology
- High silica feed water
- Cooling tower blowdown treatment and recycle
- Tertiary treated sewage treatment and reuse
- High TOC biologically active water
- Industrial water recycle & reuse
- Retrofits & existing units
