Title: Continuous purificn. of petroleum refinery effluents - by biological oxidn. and aeration between stages
IPC: B01D17/04
Filed: 1975-06-04
Abstract: Activated sludge treatment of effluents from chemical factories, and partic. those from petroleum refineries, is effected in four stages: (1) primary treatment by sedimentation; (2) intermediate treatment by equalisation, pH adjustment, coagulation, oxidn. and filtration; (3) secondary treatment by aeration between the stages, biological oxidn., clarification, thickening and aerobic digestion; (4) tertiary treatment by coagulation/flocculation, filtration and adsorption on activated carbon. The refinery effluent enters the plant at the sump and then into a conventional separator where considerable quantities of oil and solids are eliminated. The chemical effluent enters at compartment of the multi-compartment tank. The mixed effluents pass through pipes, to press. filters and to the biological treatment section; this comprises four stages, a contract stage where the effluent meets the activated sludge, a clarification stage, a thickening stage and a digestion stage. The decomtanminated water then flows through a second battery of filters and is rejected into a watercourse. When rejected the evacuated water contains at least 5 ppm. of dissolved oxygen so that it does not therefore lower the quality of the receiving stream. Biological degradation is improved by keeping the temp. in the equalising tank at 32.2-37.8 degrees C.

Patent FR-2317965-A1 (FR)
Title: Electrostatic precipitation of dust or liq. droplets from gases - with assistance from secondary liq. fog
IPC: B03C3/53
Filed: 1976-01-26
Abstract: The particles are sepd. from the gas as it passes between two electrodes, one earthed and one at a high voltage. Sepn. efficiency is increased by mechanical atomisation of liq. to form droplets in the gas and films running down the electrodes. The secondary liq. is sprayed in form of relatively coarse droplets and is atomised to form a fog of fine droplets by the high-voltage electrode. The earthed and high-voltage electrodes are arranged to create a simple (one-way) electric field between them only the high voltage electrode acting as emitter-ioniser. The gas-borne contaminants are sepd. by the combined effects of the electric field from the electrodes and the secondary liq. fog, whose particles have the same charge as the high voltage electrode. The slurry is collected and removed from the earthed electrode. Electrostatic prodn. of the secondary fog eliminates the need for spray nozzles with very fine, easily blocked passages. The design of the electrodes prevents formation of a second opposing field which would result in redispersion from the earthed electrode.

Title: Food compsns. prepn. by protein enrichment of vegetable materials - by treating first with oligoside-liberating enzyme then with a food yeast
IPC: A23L11/00
Filed: 1976-06-08
Abstract: Treatment of a vegetable material to obtain a food compsn. having a higher protein content and lower glucide content than the starting material, comprises reacting it with >=1 enzyme capable of liberating short chain oligosides, heating, and reacting with >=1 food yeast. Protein isolates and concentrates are novel which may be obtained from the above compsn. The food compsns. for animals and humans have a high nutritional value. The process enables the enrichment of a wide variety of cheap vegetable materials e.g. beans, potato and tapioca. The treatment, esp. the pretreatment, results in the destruction of anti-nutritional substances such as antitrypsin factors.
