NaCl Brine Recovery & Concentration

High Concentration NaCl Brine Recovery from RO Reject Stream

Low-cost salt is not always available for chlor-alkali and soda ash producers. Hyrec offers them an economically attractive solution to secure their salt needs and obtain fresh water in the process: Up to 26wt% purified brine can be produced by Hyrec’s technology and fed directly into chlor-alkali and soda ash production.

What This Means for You:

Hyrec OARO technology help plants to produce their own feedstock salt brine economically

  • Desalinated water and 250,000 ppm high-quality NaCl concentrate
  • Ready-to-use salt brine for Chlor-Alkali and Soda Ash production
  • Flexible designs to meet different NaCl brine needs
  • Crystallizer integration to produce crystal salt
  • RO reject / concentrate minimization

Zero Liquid Discharge

Better ZLD Management with OARO Concentration

Zero Liquid Discharge systems typically use thermal processes to evaporate wastewaters in a brine concentrator and further process them in a brine crystallizer or an evaporation pond. These systems are expensive to install and have high energy consumption.

Hyrec’s OARO Brine Concentrator can replace thermal evaporators in the middle stage of the Zero Liquid Discharge to improve energy and cost efficiencies and to enable recovery of valuable salt by-products.

What This Means for You:

Hyrec OARO technology rapidly replaces with traditional thermal brine concentrators and enable concentration step of Zero Liquid Discharge performed with a membrane technology.

  • Hyrec OARO technology is a membrane-based alternative to traditional thermal brine concentrators in the Zero Liquid Discharge process.
  • High water recovery for reuse
  • Lower operating costs
  • Recovery of valuable salt by-products
  • Very low energy consumption
  • Scalable systems
  • Brine concentration of up to 250,000 ppm
