High pressure waterjetting/waterblasting and industrial vacuum equipment play an integral role in industrial cleaning/recovery and surface preparation. The 2011 WJTA-IMCA Conference and Expo, to be held September 19-21, 2011, at the George R. Brown Convention Center in Houston, Texas, will focus on sharing information about the technology, equipment, and safety practices with industrial cleaning contractors and company representatives who contract for these services. “We invite all industrial cleaning contractors and end users who use the equipment or who are considering purchasing or renting the equipment to attend,” says association manager Ken Carroll.
