TLDR
In this paper, waste water to be treated is introduced into an enclosed gas tight oxygenation chamber, at a pressure higher than atmospheric pressure, such that oxygen from the gas is dissolved in waste water in a quantity higher than the saturation concentration value of oxygen in the waste water at atmospheric pressure.Abstract:
Waste water to be treated is introduced into an enclosed gas tight oxygenation chamber An oxygen-containing gas is also introduced into the oxygenation chamber, at a pressure higher than atmospheric pressure, such that oxygen from the gas is dissolved in the waste water in a quantity higher than the saturation concentration value of oxygen in the waste water at atmospheric pressure, thereby superoxygenating the waste water The thus superoxygenated waste water, maintained at such pressure higher than atmospheric pressure, is then passed into an enclosed gas tight filtering chamber which is separate from the oxygenation chamber and which is also maintained at such pressure higher than atmospheric pressure No other oxygen, other than the oxygen dissolved in the waste water, is introduced into the interior of the filtering chamber The superoxygenated waste water is passed through a biological filter bed within the oxygenation chamber, thereby biologically purifying the waste water to form purified water which is then removed from the filtering chamberread more

Process for treating organic wastes
TL;DR: In this paper, a method for aerobically treating water-containing organic wastes is provided, which involves mixing the wastes with an inert and non-friable bulking agent comprising a substantial component having a density less than water in the presence of active biomass.

Method and device for purifying sewage
TL;DR: In this paper, a method and apparatus for the purification of contaminated or sewage water is described, where from a presettling basin, if needed, water is conducted through a filter system in a continuous flow fashion such that the water does not settle in the filter system and is discharged from the filter systems for use without need for further purification treatment.

Method and apparatus for determining oxygen consumption rate in sewage
TL;DR: In this paper, a continuous respirometer was used to measure the respiration rate of the bacterial population included in the sewage in order to determine the rate at which oxygen is consumed or respired by the bacteria in the raw sewage.
Patent
Super-oxygenation method
TL;DR: In this article, superoxygenation of bio-oxidizable fluid in a biooxidation reactor is accomplished by continuously transferring a stream of said fluid from the top of the column of fluid in said reactor to an oxidator vessel equipped with a high-shear agitator.

Method of biological purification of sewage
TL;DR: In this article, the authors proposed a method of purifying sewage containing a strong organic pollution, which comprises two successive stages, that is, a flocculation stage and a biological filtration stage, characterized by using non-toxic and non-bacteriostatic reagents, and that the immersed biological filter is performed on a bed of material having a moderate granulometry and a surface area comprising, on the one hand, limited zones permitting the fixation and preservation of the bacterial film, even under strong and repeated washing or flushing stream conditions, and on the
