Billing itself as “The Water Opportunity Show,” WQA Aquatech USA 2006 took place March 27-31 in Rosemont, Ill. The show is all about customized water - whether it's drinking water in a home or restaurant, softened water for cleaning dishes, scale control for boilers and chillers, ultrapure water for pharmaceuticals, or specialized water for medical applications. There were 350 exhibitors on hand to greet some 5,000 visitors. Above, we see some of the action at the Pentair booth.
