Biocleaning
Many natural microorganisms are able to transform complex organic
molecules into the less complex substances carbon dioxide and
water. These organisms are carefully selected multiplied and
used for biologic cleaning.
Like in normal aqueous cleaning oils and grease are removed
from the metal surfaces by surfactants and emulsifiers and distributed
in the cleaning bath. This emulsion is then led to a separate
bioreactor, in which the micro organisms provide a continuous
treatment of the bath. A semi-permeable membrane is fitted into
the pipe which leads back into the cleaning bath in order to
keep the micro organisms in that separate reactor.
This type of cleaning can be applied where so far a normal aqueous
cleaning was applied. The higher investment costs are compensated
in the long run by lower disposal and waste treatment costs.
