Following lab scale testing, some of our clients wish to conduct pilot scale testing at their site to ensure compatibility with actual process conditions. In this case, DrM’s field service representative will work closely with our client’s personnel. Our pilot scale filter units are typically connected directly to the client’s filtration process. DrM has a wide range of pilot filters to meet all possible process requirements.
Our pilot filters are fully equipped, self-standing units with automated valves and control system. A gas-driven diaphragm pump can be included in the rental unit. The filtrate flow rate must be monitored with a scale or a calibrated drum. In addition, filter cake thickness must be measured and cake samples taken for subsequent moisture assay. Our pilot filters are designed for maximum 50 mm thick cakes. There are two modes of operation possible with our pilot filters. They can be operated as a dry cake FUNDABAC® filter or as a thickened slurry discharge CONTIBAC® filter. For the thickener mode of operation, a conical bottom is used instead of the sliding gate valve. The conical bottom has a ball valve for the concentrated underflow.
