ABSTRACT:
A filtration system comprising a filter cassette having integrated ultrasonic transducers incorporated therein, and a method for using the same. The integrated system of filters and transducers can be hardened for use in hazardous environments, and is particularly suitable for the implementation of sonication in cross flow filtration processes further integrated with a manufacturing process. The system provides cost savings both in terms of less equipment and space for cleaning processes on the manufacturing floor.
