RO Infinity (ROI)
Breakthrough Reverse Osmosis Technologies for Sustainable MLD and Resource Recovery Solutions
Many of today’s water and wastewaters cannot be efficiently treated with conventional membrane or thermal technologies. Gradiant has developed RO Infinity (ROI), an advanced platform of membrane-based solutions for complex water & wastewater challenges, that combines our patented CFRO technology with innovative reverse osmosis (RO) membrane processes. ROI solutions enable customers around the world to achieve desalination, brine concentration, brine mining, and sustainability goals.
ROI systems are built with commercially available membranes and components for low-cost and easy maintenance. These units are designed & assembled in modular form factors with proprietary process and control technologies, and backed by one of the most experienced engineering and service teams in the industry.
Benefits of RO Infinity
Minimum Liquid Discharge (MLD)
Recovers up to 99% final brine concentrations to the saturation limits of salt (TDS up to 260,000 mg/L NaCl). This reduces the required capacity of downstream ZLD systems with cost savings of 60% versus thermal systems.
Maximize Production
Extract more fresh water, recover higher concentrations of valuable resources, and minimize waste disposal — all at lower pressures and energy usage which reduces total water costs.
Maximize System Availability
ROI systems are intelligent, adjusting for varying feedwater and operating conditions to tolerate highly variable feedwater quality, and experience less fouling and scaling than conventional systems.
