Product catalog summary
Introduction
Zero Discharge Desalination (ZDD) is a cutting-edge membrane desalination technology designed to achieve higher water recovery rates than existing alternatives. It is particularly suitable for treating brackish groundwater, retrofitting reverse osmosis/nanofiltration systems, and expanding plant capacity where water scarcity is a concern.
Technology Description
ZDD employs electrodialysis metathesis (EDM) to remove salts from water, achieving high product water recovery. The process involves ion substitution to prevent precipitation of divalent salts, resulting in higher recovery levels compared to conventional methods. The system can integrate additional technologies to address specific contaminants, such as silica.
Applications
  • Inland brackish groundwater treatment for potable water
  • Retrofitting RO/NF systems for improved recovery
  • Plant capacity expansion as an end-of-pipe addition
Performance Data
The ZDD process offers a cost-effective solution with water recovery rates between 95-99%, significantly reducing waste volume and brine disposal costs. Byproducts can be salable or reusable, and the system is designed for easy operation and maintenance. Pilot testing is available to demonstrate its environmental benefits.
Technical Specifications
The document provides detailed data on the concentration of various ions in different stages of the process, highlighting the efficiency of ZDD in converting sparingly soluble salts into highly soluble ones, such as converting CaSO4 into CaCl2 and Na2SO4.

ZDD is a new membrane desalination technology that achieves higher recovery than any alternative available in the marketplace. Unparalleled in its ability to sustain water resources, ZDD is ideal for brackish groundwater treatment, retrofitting for brine streams from reverse osmosis/nanofiltration (RO/NF) systems, as a plant capacity expansion add-on, and other applications where water scarcity and limitations in recovery must be overcome. ZDD can be applied to reduce or el i minate the need for more costly, less environmentally friendly disposal options such as deep well injection, large evaporation...
