What is the difference between the BHS pressure plate filter and the “spinning disk” filters?
Spinning disk filters are also commonly used for clarification. While these units overcome some of the special handling requirements of manual filters, they add mechanical complexity to the process as well as special cleaning requirements. Spinning disk filters require drive motors, gear box assemblies (including gear box housing, gear reducers, bearings, shaft bearing arrangement and bushings, torque loadings, etc.), mechanical seals (either single or double with special maintenance and cleaning) and unique installation concerns such as center of gravity due to the spinning plates, static and dynamic balancing and bearing lubrication and design to ensure no exposed threads and cleanability issues, and overall maintenance of these components. The BHS units use vibrating plates which eliminate motors, gears, rotating seals, etc. and many of the operational issues of the spinning units.
