You can find some introductory information about these devices through google.  They are sometimes called filter presses, so you can also search using this term and find relevant information.  Searches such as how plate frame filter works or filter press function will retrieve some useful websites.  You also can find several diagrams detailing how they work by searching in Google Images for plate and frame filter diagram.

COM Library has some technology books that discuss the device, albeit briefly.  Follow the link below to our eBook collection and search for "frame filter" or "filter press".  After you've selected a book, click on it and then open its full text.  You can then search the full text through the search icon on the top right, and try searching for plate and frame filter or something similar.  The eBook will find all the places in the book where the words appear, and you can click on any of them to view the page they are on.

As for finding biographical information on the frame filter's inventor, this does not appear to be a piece of information that can be retrieved through the library's resources or the information available online.  However, if you want to find some names associated with filter press development, you can search Google Patents. Searching for plate and frame filter will retrieve several patents related to the device, which include the names of people involved with the patent.
