MLD and ZLD are becoming table stakes as discharge limits tighten and water-reuse targets climb. The problem is the thermal last mile: evaporators and crystallizers carry most of the energy load and most of the cost. This session walks through a membrane-led process that pushes brine concentration much further before any thermal step, using IDE’s MaxH2O Desalter and a low-salt-rejection reverse osmosis (LSRRO), with a semiconductor brine case study behind it.
What you’ll learn:
- Why conventional MLD/ZLD stays energy-intensive, and where the thermal step dominates the energy bill.
- How LSRRO pushes concentration well beyond the conventional RO range by letting NaCl pass selectively and easing the osmotic-pressure penalty.
- Why LSRRO rejection depends on brine composition, and how the process model accounts for that as the brine concentrates.
- What a representative semiconductor brine reveals about energy, chemicals, CapEx, and OpEx when you compare the conventional train to the novel one.
- How pre-concentration with MAXH2O Desalter enables safer, more reliable LSRRO operation.
