NESMD
Nanophotonic-Enabled Solar Membrane Distillation (NESMD)
Developed with Rice University and funded in part by the National Science Foundation and the US Department of Energy, NESMD is an innovative process that achieves solar-thermal energy collection and water purification simultaneously.
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.
NESMD Technology
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
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:
Small residential and multi-unit residential systems (400 – 1,000 gpd)
Transportable / truck mounted system for emergency and military use (2,000 – 5,000 gpd)
Larger systems for municipal and humanitarian use (10,000 – 500,000+ gallons per day)
