Milk industry
For the milk industry, waste waters from different
cleaning steps were treated with different membranes.
The concentration of constituents in these rinsing
waters varies greatly over flushing time. With a separate
collection of variable contaminated parts of these
flushing waters into streams that either can be reused
without treatment, can be fed to membranes directly
or need a more complex treatment scheme, including
e.g. biological reactors in combination with membranes,
the necessary treatment schemes can be applied
most cost-effective and purposeful.
Apart from this research close to the production processes,
experiments were conducted with the effluent
of the waster water treatment plant of a milk processing
company, whether there are opportunities to recycle
the effluent as boiler feed water with reverse osmosis.
The quality requirements for boiler feed water
are demanding, an almost complete removal of inorganic
and organic constituents is required.
