During the experimental investigations the
influence of different silicon deaerators, which are
added into the pulp to prevent the foam formation, on
oxygen saturation of waste waters formed during the
paper goods production from wastepaper was estimated.
It was shown that deaerators significantly reduce oxygen
concentration in waste waters and, consequently,
increase its danger for natural water basins. The
indicators of performance of the flotation in removing
deaerators from waste water were reviewed.
