Nanophotonic-Enabled Solar Membrane Distillation (NESMD)
Photothermal nanoparticles are coated on a hydrophobic membrane. Sunlight reacts with the nanoparticles generating heat on the membrane’s surface. The heat evaporates the feed water generating clean water vapor that flows through the membrane, leaving the dirty feed water behind.
Localized Water’s NESMD technology has advanced past prototype feasibility and is now on a path to full commercialization within 12-24 months
Small- Scale Prototype
Second Generation Prototype
A NESMD system on 1 acre of land can achieve 80-90% recovery on seawater producing roughly 130 gpm of fresh water during sunlight hours. The 4 x 8 feet NESMD modules scale linearly.
LWS is currently designing NESMD water purification systems that can modularly scale for expanding water needs for the following uses for which it has obtained exclusive rights:
