PULSATION PRESSURE-ASSISTED OUT-IN TYPE SANDWICH CERAMIC MEMBRANE AND SYSTEM THEREOF

摘要

PURPOSE: A pressure-assisted out-in-type sandwich ceramic membrane is provided to enhance the speed of filtering, prevent the deposition of filtered materials and reduce the cost of production. CONSTITUTION: A pressure-assisted out-in-type sandwich ceramic membrane(100) comprises large holes inside and small holes outside. The ceramic membrane comprises a form-typed core(110), a plate(120) which is formed on the side of the core and the lower part of the core and a coated layer(130) which is coated on the outside of the plate. The core comprises channels for air which are connected to each other. The plate comprises small channels for air which are smaller than the core. The coated layer comprises small channels for air which are smaller than the plate.
