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.
