Replacement of MICRODYN BIO-CEL
The replacement of the BC-L cassette might either be done in the filtration tank or by lifting out the
complete module. In both cases make sure you remove heavy sludge deposits before lifting the module
or the cassette. We do highly recommend to perform an intensive cleaning before starting with
replacement works.
1.
Once the module is free of sludge and lifted out of the tank / and the tank is drained completely, continue
with the next steps.

Preparations for lifting

For lifting via crane you have to install the
lifting eye bolts

Use a proper lifting tool for lifting (see also
accessories)

Make sure the module fixation to the tank is
Ioose

Make sure that air and permeate pipework is
disconnected
Make sure the weight of the module is
maximum 1500 kg. Heavy sludge
deposits have to be removed before lifting
module!
Make sure the lifting equipment does not
touch the white membrane sheets when
being attached to the module
Lifting via crane is only allowed in vertical
direction, no lateral pulling is allowed.

In case you use the existing permeate
connector (and o-ring), you would need to
dismantle it.

Open the screws (M10x90). The screws are
fixed with screw lock, so opening might be
not very easy.
This work should be done by 2 men,
since the permeate connector is very
heavy.
