Brine Concentration

WEC Projects designs, manufactures and supplies a comprehensive range of packaged treatment systems utilising membrane technology.

When it comes to reducing the environmental liability – reducing your waste volume and making it more manageable becomes especially important. Various membrane technologies or evaporation techniques may be used to decrease the volume of any concentrated brine streams produced from wastewater treatment processes.

Due to new regulations, it is becoming harder to store brine solutions in dams due to the long-term environmental concerns:

“The national norms and standards under the Act prohibit landfill disposal of brine or waste with a high salt content (>5%) and a leachable concentration for total dissolved solids of >100 000 mg/l, (ban effective from 2021).”

National Environmental Management: Waste Act (59 of 2008)

Waste streams from general industry, mine processing and acid mine drainage, containing high concentrations of dissolved salts, as well as concentrate streams from membrane processes, must be disposed of responsibly and in an environmentally acceptable manner.

Benefits

Reducing the volumes and increasing the salt concentrations of your brine streams leads to the following benefits

  • Lower long-term life cycle costs

  • Enhanced environmental governance and sustainability

  • Reduced size of storage or disposal dams

  • Potential resource recovery with regard to valuable salts or minerals

  • Increased water reuse and recovery

Services We Offer

WEC Projects provides various techniques to increase brine concentration

Brine concentration improvements are vital in wastewater management activities, especially when resource recovery is required or options that are needed to head towards zero liquid discharge.

AMBC Technology

AMBC technology is an advanced membrane technology  that has the ability to concentrate brine the salt concentration in brine streams up to 160,000 mg/l.  It is a non-thermal system using only electrical energy, thereby consuming a fraction of energy compared to thermal evaporation systems.

Additional advantages include lower operating costs, less expensive maintenance, and ease of operation.
