Not necessarily using technology for frac water (there are better systems for that) but all of the different needs that refineries have. Refineries have millions of gallons of water they have to treat daily, and with the new environmental regulations they are always looking for a system that can treat the water and avoid the use of chemicals. I believe that is the avenue they are pursing. Also airports have alot of water they wash runways with that pick up solids and contaminants that the EC units are perfect for. They talked to Shell yesterday.... not a stock shell!!
