Recovery to Acid and Alkaline (R2A) Technology
Technical introduction
R2A technology is the membrane-based electro-separation process to separate and convert the anions and cations from wastewater into acid and alkali solutions. Compared with conventional thermal ZLD process for brine treatment, R2A technology achieves carbon reduction and resource circulation simultaneously in the wastewater treatment and reclamation.

Detailed technical introduction
Applications
•SW desalination/ ZLD: reduce conductivity for brine
•Wastewater treatment: reduce conductivity for waste liquor
•Manufacturing process: recovery of organic waste containing inorganic ions
Applications of R2A technology
Features
•Production of HCl, H2SO4, and NaOH with purity >90% and concentration >5 wt%.
•Reclaim valuable resource
•Achieve zero waste goal for wastewater treatment
