Functional Description
The MICRODYN BIO-CEL
®
XS-1 pilot plant serves to separate the aerated sludge from cleaned
waste water by means of membrane filtration. The aeration tank of the pilot plant is fed with the
mechanically pre-treated waste water via flexible pipes. Before the effluent reaches the filtration
tank it is flowing through a 1mm bar screen to remove any coarse materials (optional). The
filtration tank is a round tank with an inner diamerter of 75cm and houses the membrane module.
It is possible to operate the filtration tank with an intermittent denitrification, in this case a separate
anoxic tank for the denitrification is not required.

Pilot plant and auxiliary equipment
The raw waste water is transported into the plant by means of an external pump. Feed supply
and sludge discharge are not part of this plant. They must be provided by the leaser.
The membrane filtration process consists of the steps:
•
filtration
•
backwashing
•
relaxation
•
(de-aeration)
