FlexEDR can treat saline agricultural wastewater for reuse: preserve ions of value (calcium) while removing the pollutants (sodium).

FlexEDR can bolt-on to existing reverse osmosis (RO) plants; increasing recovery and plant reliability.

Solutions for:

  • Agriculture water treatment
  • Phosphogypsum waters
  • Recycle fertilizer products of value

Benefit from:

  • Reuse wastewaters
  • Recycle fertilizer products of value
  • Reduce freshwater demand
  • Meet surface discharge requirements
  • Reduce waste volume, reduce trucking
  • Maximize water recoveries
  • Mobile pilot plants available

How to Manage Brine Disposal & Treatment

The many options for managing brine, a term for saline wastewater from industrial processes, fall under two categories: brine treatment and brine disposal. Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge).
