Multi-Stage Systems For Waste Water Oxidation
US Patent:
4206047, Jun 3, 1980
Filed:
Jul 13, 1978
Appl. No.:
5/924187
Inventors:
Mikkel G. Mandt - Cedar Falls IA
Assignee:
Houdaille Industries, Inc. - Fort Lauderdale FL
International Classification:
C02C 106
US Classification:
210 7
Abstract:
Methods of the activated sludge type for treating sewage utilizing specific mixing regimes and oxygen demand rates. The systems are particularly advantageous in utilization of relatively pure oxygen in a final stage treatment zone, and in which no more than 10% of the total oxygen requirement for all zones is required for high purity oxygen.
Nitrification-Denitrification System
US Patent:
4290884, Sep 22, 1981
Filed:
Aug 18, 1980
Appl. No.:
6/179239
Inventors:
Mikkel G. Mandt - Cedar Falls IA
Assignee:
Clevepak Corporation - White Plains NY
International Classification:
C02F 330
US Classification:
2101953
Abstract:
Activated sludge treatment system for removal of pretreatment BOD and nitrogen values from waste water, utilizing a mixed liquor tank comprising a nitrate cracking channel zone, a denitrification channel zone and an aeration zone in specified relationship and adapted to provide specified operating conditions in the respective zones.
Multi Stage Flocculation Treatment System
US Patent:
4206052, Jun 3, 1980
Filed:
Jan 12, 1978
Appl. No.:
5/868801
Inventors:
Mikkel G. Mandt - Cedar Falls IA
Assignee:
Houdaille Industries, Inc. - Fort Lauderdale FL
International Classification:
C02B 120
US Classification:
210 49
Abstract:
Systems for flocculation processing in water purification treatment in which a first jet flash mixing field of relatively high specific energy requirement and turbulence intensity is provided for intimate mixture of the flocculant and influent water to produce a thoroughly mixed product stream having residual energy, and in which the product stream from the first mixing field is used as the motive stream to power a flocculation field of lower specific energy requirement and turbulence intensity.
