LG Water Solutions, part of LG Chem, LTD., manufactures the full line of NanoH2O™ seawater, brackish water and residential reverse osmosis (RO) membranes.
NanoH2O RO membranes are developed based on innovative Thin Film Nanocomposite(TFN) technology which improves membrane performance by embedding benign nanomaterials in the surface of the membrane. Armored with this patented nanotechnology, NanoH2O RO membranes deliver best in class flux and salt rejection.
The membranes are provided in various spiral wound configurations that fit easily into new or existing RO systems. NanoH2O RO membranes purify water from a broad range of sources, dramatically improving productivity and product water quality.

The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.
Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.
Depletion of water supplies for potable and irrigation use has been a major problem in the world. Seawater desalination by reverse osmosis has become a common solution to address these demands. Using alternative sources of water requires implementation of increasingly stringent standards of water quality obtained by reverse osmosis processes, and boron is one of the most challenging contaminants in the final product.
Malta is an archipelago of three islands situated in the Mediterranean Sea, around fifty miles south of Sicily. There are no rivers of any significance on the islands, and the sparse annual rainfall is only about 500 mm. There is a water deficit in Malta. It occurs especially in summer when there is a great demand from the farmers for their irrigation and from the tourism sector.

Depletion of water supplies for potable and irrigation use has been a major problem in the world. Some areas in the US are facing challenges to reliably provide clean water to its population. These challenges require municipalities to pursue sustainable supply options such as Indirect Potable Reuse (IPR). IPR has become a sustainable alternative water supply. In IPR, municipal wastewater is treated and injected into a groundwater aquifer via vadose zone wells, spreading basins or other means in which water percolates through the unsaturated soil into the aquifer. The intent of IPR is to diversify water sources in order to maximize reliability of the region’s water supply.
