The ultrasonic tubular resonator, a device for removing surface contamination, is making its way to chemical process tanks. Cleaning tanks and reactors with this device is less expensive, less energy intensive, and more environmentally friendly than with conventional cleaning methods, according to results of a demonstration project by DuPont Merck Pharmaceutical.

The grant requires DuPont Merck to make available the results of the demonstration project. These results were presented in May at two seminars organized by the New Jersey Technical Assistance Program for Industrial Pollution Prevention. Ultrasonic cleaning of reaction tanks and reactors is simple, says Angelo C. Piro, president of the U...
