=Nanotechnology in Water Purification=
This section lays out the landscape of nanofiltration technology segment of water purification in detail covering the market information, major players, company profiles of start-up companies and university research going on in the nanofiltration for water purification.
<br>
==Market Size ==
* The global market for nanotechnology products used in water treatment was worth an estimated $1.4 billion in 2010

==Startups==
This section profiles some of the start-up companies in the nanofiltration segment of water purification.
<br>
===Company Profiles===
<br>
====NanoH2O====
NanoH2O, Inc. designs, develops, manufactures and markets reverse osmosis (RO) membranes that lower the cost of desalination. Based on breakthrough nanostructured materials and industry-proven polymer technology, licensed original TFN technology from University of California, Los Angeles, NanoH2O<nowiki>’</nowiki>s QuantumFlux membranes dramatically improve desalination energy efficiency and productivity. QuantumFlux seawater reverse osmosis (SWRO) membranes, Standard 61 certified by NSF International for the production of drinking water, deliver the highest flux and the highest salt rejection of any SWRO membrane on the market. QuantumFlux membranes are available in standard 8-inch (20 cm) diameter elements that fit easily into new and existing desalination plants, purifying water from a broad range of sources with improved productivity and water quality. NanoH2O is the 2011 Aquatech Innovation Award Winner in the Water Supply category. Quantum Flux membranes are installed in over 50 commercial sites across six continents, representing over 80,000 m3 per day (21 million gallons per day) in cumulative capacity.
The startup has developed its technology based on research from the University of California at Los Angeles. Its formula adds a nanomaterial to a conventional polymer membrane for desalination in order to alter its structure and make it easier for the water to pass through while it blocks out salt and other minerals. The water is potable afterward, but utilities sometimes add back some of the minerals that are filtered out before delivering the water to homes and businesses.
