The chambers include water circulators which stir the water within the chambers and the downstream chambers having floating on the water surface high surface area media which carries bacteria. Preferably the water flows through the downstream aerobic chamber in a carousel-like fashion.

NOVEL PSEUDOMONAS MICROORGANISM FOR
Disclosed is a process for treating waste water containing high levels of organic waste products which employs a series of chambers through which the water flows with the upstream chainhers promoting anaerobic digestion of the waste products and the downstream chambers prorooting aerobic digestion of the waste products. The upstream chambers are charged with a sludge preferably which, because of the conditions maintained within the chamber, has an ashlike characteristic upon being dried and does not contain high levels of water included within it. It is sometimes desirable to recharge the chamber with sludge since this sludge acts as a buffer that can digest shock loads of waste products having
BIODEGRADATION OF LIQUID SCINTILLATION COCKTAILS James H Wolfram, Robert D Rogers An apparatus for the biodegradtion of toxic organic solvents contained in liquid scintillation cocktail (LSC) wastes is disclosed, as well as a method for its operation. Additionally, a novel microorganism, Pscudomonas sp N N R L B18435, is disclosed for the biodegradation of the organic solvents contained in such wastes. The apparatus is capable of operating with solvent 488
PATENT ABSTRACTS concentrations greater than 5,000 ppm and emulsifier concentrations greater than 2,000 ppm. Rates of solvent biodegradation range from 0.095 mg/L.min to about 7.0 mg/Lmin. 4867883 HIGH-RATE BIOLOGICAL WASTE WATER TREATMENT PROCESS USING ACTIVATED SLUDGE RECYCLE Glen Daigger, James R Borberg, Liliana M Morales assigned to Hampton Roads Sanitation District of the Commonwealth of Virginia A high-rate biological waste water treatment process for removing organic matter, phosphorus and nitrogen nutrients from municipal waste water comprising the steps of mixing the influent waste water in an initial anaerobic reactor zone to maintain the biological solvents in suspension with a denitrified mixed liquor from a downstream anoxic reactor zone, typically at a flow rate of 0.5 to two times the waste water flow rate. The reactor zone serves to select microorganisms capable of accumulating quantities of phosphorus in excess of that required for simple cell growth and reproduction. The phosphorus removal occurs due to the removal of excess sludge (waste activated sludge) produced in the process wherein such sludge can be removed from the clarifier undertow or as a mixed liquor directly from the biological reactor, 4869824 BUBBLE PLATE SYSTEM FOR BIOLOGICAL PURIFICATION OF AIR AND WASTE WATER Thomas Melin, Hubert Stracke, Otto Barth, Cologne, Federal Republic Of Germany assigned to Bayer Aktiengesellschaft The outgoing gas or waste water is conveyed through a gas-liquid contact apparatus in which biological purification takes place. A bubble plate-type column (2) is used as gas-liquid contact apparatus. The biomass is distributed over the plates (3) in the form of an aqueous suspension with a layer height corresponding to a liquid content per plate greater than 0.07 m3/m2, preferably greater than 0.15 m3/m2 of column cross-sectiOn. During the biological purification of gas, the gas to be purified is supplied at the
4a9
lower end of the bubble plate-type column (2). It then flows through the plates (3) and issues again as purified gas at the top of the plate column (2). When the plate column is used for purifying waste water, the waste water to be purified is conveyed from top to bottom through the plate column (2) and is traversed by air, oxygen or oxygen-containing gas. At the same time, a proportion of the biomass is separated from the purified waste water and re-circulated into the entering waste water or into the column. The waste water to be purified flows successively over the plates (3) to the liquid outlet (l 1). From here, the clarified waste water flows out through the overflow (13). This process is suitable, in partitular, for highly charged waste water, particularly ifa compact structure is required during construction of the apparatus. 4880473 PROCESS

PRODUCTION OF FERMENTABLE SUGARS FROM BIOMASS Donald S Scott, Ja Piskorz, Waterloo, Canada assigned to Canadian Patents & Development Ltd A process for the production of fermentable sugars from wood or other cellulose-containing biomasses, comprises the steps of (a) hydrolysing the biomass with a dilute sulfuric acid to dissolve hemicellulose while leaving most of cellulose in a solid phase, (b) separating the c¢llulose~ containing solid phase, (c) subjecting the solid phase to rapid pyrolysis at a temperature of 400 degrees-600 degrees C. at atmospheric pressure, preferably in a fluidized bed reactor with a short vapor residence time, to obtain a crude pyrolysis product by condensing the pyrolytic vapors, (d) adjusting the water content of the crude product to form an aqueous phase with high carbohydrate content and a water-insoluble phase containing lignin-derived material, and (e) separating the aqueous phase. Optionally, the aqueous phase may be purified, e.g. by absorption. 4880542 BIOFILTER TREATMENT
