HERO™

High Efficiency Reverse Osmosis

High efficiency reverse osmosis (HERO) is a reverse osmosis technology designed to treat high silica and difficult-to-treat feed wastewater. By effectively preventing membrane fouling or scaling, the HERO process offers higher recoveries as well as significant operational benefits. 

The process excels in treating cooling tower blowdown, outperforming conventional reverse osmosis. HERO can also economically replace or supplement an evaporation process to achieve zero liquid discharge (ZLD).

Advantages of High Efficiency Reverse Osmosis

01 / 06
High Recovery

High Recovery

HERO technology is designed to achieve a high water recovery rate (>90%), enabling a significant percentage of the feedwater to be converted into purified water. 

High Salt Rejection

High Salt Rejection

HERO technology is capable of efficiently removing salts and other impurities from water, resulting in a high salt rejection sa

High Flux

High Flux

HERO technology is known for its high flux, which refers to the rate at which water permeates through the membrane.

Reduced Fouling

Reduced Fouling

Hero technology is designed to minimize fouling, which helps maintain consistent performance and reduces the frequency of cleaning and maintenance. 

Lower Operating Costs

Lower Operating Costs

The combination of high recovery, salt rejection, and reduced fouling contributes to lower operating costs.

Reduced Maintenance

Reduced Maintenance

HERO technology’s design aims to minimize fouling and scaling, leading to reduced maintenance requirements. 

Economic Considerations 

Besides having technical superiority over conventional reverse osmosis, the HERO process offers significant economic advantages.

  • Higher Recovery - Since the HERO system allows increased water recovery, the cost per gallon for pure water production is reduced. 
  • Minimal Offline Cleaning - Operating data shows a frequency requirement of once a year for HERO vs. twice to three times a year for conventional RO. Substantially reduce the time your system is offline for membrane cleaning.
  • No Proprietary Chemicals – The HERO technology runs on common chemical feed requirements, allowing you to cut the cost of expensive cleaning chemicals typically required.
  • Eliminate Redundancy – Due to HERO’s high pH operating environment, it is in a “continuous cleaning mode,” thus eliminating redundancies in capital equipment to compensate for cleaning downtime.
