BIO-CEL Laminate
Module
The single laminate sheets are combined in the module. The module housing provides protection
for the membranes and mechanical stability. It also helps to direct the cross flow of air and
activated sludge through the laminate sheets.
The membrane modules of the MICRODYN BIO-CEL
®
XS-1 series are made of polyethylene
(frame), PVC (membrane cassettes and aeration system) and a few parts of stainless steel
(clamping elements). They are resistant to corrosion when used in activated sludge. The aeration
system is integrated in this module and is located at the base of the module. The air is required
in order to generate a small amount of cross flow in the module and on the membrane surface in
order to be able to discharge the sludge out of the module. The pressure differences and the
turbulences created by the air dissolve adhering particles from the membrane surface. The fine-
bubble aerators are made of polyurethane (PUR) with small slit openings to achieve the highest
possible oxygen yield and to prevent sludge penetration even when the modules are in stand-by.
