TDS is developing an Electro Hydraulic device that has the potential of faster, safer, and less expensive scabbling of contaminated concrete surfaces. In the device, shock waves and cavitating bubbles are produced in water by the electric pulses, and the direct and reflected shock waves impinging on the concrete surface result in the crushing and cracking of the concrete. Control of the pulse energy, frequency and traverse speed control the depth of the scabbling action. performance thus far, has demonstrated the capability of the bench scale unit with a single pair of electrodes to scabble a swath 3 inches wide, up to 1 inch deep at a rate of up to 12 inches per minute. A unit with multiple electrodes will increase the width of the swath.
