Evaporation and crystallization remain the largest energy consumers in minimal and zero liquid discharge systems, while conventional RO is limited by scaling and osmotic pressure. This presentation proposes a process that combines a desalter with controlled precipitation and low salt rejection (LSR) membranes to concentrate brine far beyond conventional RO before crystallization.
