An Alumina Ceramic Filtration Module is a multichannel tubular membrane made from high-purity alumina for microfiltration or ultrafiltration. It filters liquids by allowing permeate through the porous membrane while retaining solids or oil. Its strength and tolerance to wide pH and high-temperature cleaning make it suitable for demanding industrial and municipal filtration.
Alumina Ceramic Filtration Module Benefits
-
Multichannel tubular design
The module uses a multichannel alumina ceramic support to deliver a highly effective membrane area in a compact footprint, allowing higher system capacity per housing and per skid. -
High mechanical strength under pressure and temperature cycling
The dense alumina body tolerates repeated start–stop cycles, high crossflow velocities and frequent CIP without deformation, reducing the risk of element breakage in demanding plants. -
Stable permeate performance in high-fouling feeds
The ceramic membrane structure maintains stable flux in feeds containing suspended solids, oil droplets or colloids, with good flux recovery after chemical or backflush cleaning. -
Compatibility with aggressive cleaning regimes
The alumina membrane tolerates oxidizing agents and wide pH cleaning sequences, enabling more intensive cleaning programs and extended operating life compared with many polymeric membranes. -
Interface-ready module ends
End designs can be supplied to match standard clamp, flange or potting arrangements, simplifying drop-in replacement of existing membrane elements in OEM or retrofit systems.
