Abstract
Ceramic filter elements ( ) have a feed surface covered with a ceramic filter membrane ( ). As a feed liquid flows over the feed surface, a portion of the liquid passes through the membrane and the filter and is discharged through a discharge surface as a permeate liquid flow. Between the feed and discharge surfaces, the filter element includes an impermeable surface portion ( ) which contacts a seal or gasket assembly ( ). The seal or gasket assembly includes two seal portions ( ) which define a channel ( ) in between. The channel connects with a discharge channel ( ). In this manner, any liquid leaking between the filter element and another filter element or a housing ( ) enters the discharge channel ( ). Liquid in the discharge channel indicates a leak in the seal and potential contamination of the permeate liquid.
