ABSTRACT:
An improved rigid filter plate for sludge dewatering is comprised of a filter element of two or more sizes within the range of 0.2 to 0.002 inch of irregular hard particles of aluminum oxide or similar materials, and of a supporting element of larger particles all bonded with an adhesive bonding agent. A process for manufacturing the improved rigid filter plate is also set forth.
