摘要： A process and apparatus for removing suspended matter from suspensions by filtering through foams, in which the suspended matter retained in the foam (polyurethane foam produced by foaming with water vapor being preferred) is substantially flushed out by expressing the liquid held in the foam, and is removed as a concentrate. This for the the first time permits the removal of suspended matter from continuously flowing suspensions without the flow of the suspensions having to be interrupted in order to clean the filtering means.
摘要翻译：通过泡沫体过滤除去悬浮物悬浮物的方法和装置，其中保留在泡沫中的悬浮物（优选通过用水蒸气发泡制备的聚氨酯泡沫）通过表达保持在泡沫中的液体基本上被冲洗掉，以及作为浓缩物去除。这是首次允许从连续流动的悬浮液中除去悬浮物，而不会使悬浮液的流动不必中断，以便清洁过滤装置。

摘要： A process for the biological purification of effluent which is contaminated with nitrogen in the form of ammonium, nitrite or nitrate ions or in the form of organic compounds, by oxidizing the nitrogen under aerobic conditions and reducing the nitrogen under anaerobic conditions, wherein the sewage to be treated, mixed with activated sludge, is subjected, in an aeration basin, to oxygen-containing gas bubbles introduced from below and is thereby simultaneously enriched with dissolved oxygen, to oxidize carbon compounds and nitrogen compounds, and transported upward, by the buoyancy of the gas bubbles, releases gas at the surface of the liquid and, due to the higher average density of the mixture of lower gas content, in part automatically again flows downward in the aeration basin, to undergo further aeration, while in part it overflows into a denitrification basin which communicates with the aeration basin through an opening at the liquid surface, and an opening at the bottom of the partition, is mixed, in the denitrification basin, with the contents thereof by mechanical means and flows back, through an opening near the bottom, in the partition, to the aeration basin.The invention further relates to an activated sludge basin, wherein jet aerators are arranged parallel, and horizontally, at the bottom of the basin, a vertical partition divides the basin into an aeration compartment and a denitrification compartment, both compartments possessing jet aerators, and passages in the partition connect the two compartments of the basin in the area of the surface of the liquid, and in the vicinity of the bottom.
