The three key inventions made it possible to produce potable water from almost any source – in particular seawater – on a commercially viable basis. His designs avoids the use of chemicals needed in the pre- and post treatment of water during the Desalination process, thus enabling desalination plants to pump the Brine reject back to the source (Sea) without contamination thereof.Another breakthrough was the reduction in overall energy required to sustain Osmotic pressures necessary to remove the lonic constituents from Seawater. The Electro Magnetic Field Device, (EMF) patent also prolongs membrane life significantly, and reduces the replacement cost over the lifespan of a Desalination Plant.Mr Graham recently became the first person to reduce Boron levels in Desalinated Seawater from 6ppm (Parts per million) which is considered a health risk by the World Health Organisation (WHO), to below 0.6ppm, the allowable levels in potable water, with his patented process.
