Description
Pall Membralox ceramic membranes are asymmetric multi-channel membranes composed of a porous alumina support and a filtering layer (alumina, zirconia, titania).
High compactness of the multichannel membrane combined with high permeability allows the treatement of large volumes with high throughput.
The Membralox GP ceramic membranes range with longitudinal permeability gradient, ensure an homogeneous and calibrated flux along the flow channel, thus optimum utilization of membrane surface within a stable microfiltration regime.
Membralox filtration modules are the key element in process reliability.
