Zero Liquid Discharge (ZLD) and Minimal Liquid Discharge (MLD) become Lower Cost through Reverse Osmosis Innovation
Saltworks is pleased to announce that recent advancements in reverse osmosis technology are now commercially available. Malcolm Man of Saltworks notes “we are changing the cost equation for brine management and minimal liquid discharge. In the MLD and near ZLD space, advanced reverse osmosis can now do two things previously thought unattainable:
- Reduce conventional RO brine volumes by 50%, achieving brine concentrations of 130,000 to 150,000 mg/L TDS with spiral wound RO membranes.
- Treat industrial and produced waters with high organics and solvents, while maintaining membrane integrity.
Throughout 2019, Saltworks has been working with industrial customers and a leading RO membrane supplier to refine and thoroughly test the technology. It has now been demonstrated through repeated successful pilots in mine water management, cooling tower blowdown, brackish water desalination, oil & gas produced water, and industrial wastewater treatment. A cooling tower blowdown treatment case study was recently published by Saltworks.
The advanced RO accomplishments involve the marriage of specialized RO membranes and process-control innovations. An exciting partnership in this regard will be announced in the future. Interested readers can learn more about the technologies below or contact Saltworks.
