5811008 Process and system for purification of waste water
New Patents
fume cupboard by containment of toxic materials, if present, in the toxic work enclosure.
5810895 ROTATING PACK BED FILTER WITH CONTINUOUS CLEANING SYSTEM Staehle Richard C; Cash James T Flemington, NJ, UNlTED STATES assigned to Regenerative Environmental Equipment Company lnc Apparatus for removing a wide variety of differing solid and aerosol waste materials from effluent or exhaust streams produced by an industrial process. This invention may be especially useful as a preor post-conditioner of the effluent to prevent plugging in any number of available pollution control devices. More particularly, a rotating pack bed filter removes solid and aerosol waste materials, if present, from an effluent and simultaneously regenerates the filter media by (1) heating to thermally decompose the collected material trapped in the filter media into a residue and to drive off gaseous pollutants carried by the collected material and (2) cleaning to remove the residue from the media.
5810943 WASHER APPARATUS WITH WASTE WATER PH NEUTRALIZATION SYSTEM AND METHOD FOR THE PH NEUTRALIZATION OF WASTE WATER Caron Daniel; Lynch Stephane; Giguere Daniel; Boutin Richard Beauport, Quebec, CANADA A washer apparatus includes a washing chamber (W) with a plurality of spray nozzles (N) and a pump (Pl) for circulating the washing fluid (F) through the spray nozzles (N) for cleaning the contents of the washing chamber (W). A pH sensor contacts the washing fluid (F) and a digital pH controller connected to the pH sensor generates digital pH values of the fluid (F). An acid neutralizing system and an alkaline neutralizing system are provided for selectively

injecting acid neutralizer and alkaline neutralizer into the reservoir (S, T), respectively. An electronic controller controls the operation of the washer and the acid and alkaline neutralizer injection systems (80,90) in response to the pH of the washing fluid (F) as determined by the digital pH controller (30).
5811008 PROCESS AND SYSTEM FOR PURIFICATION OF WASTE WATER Von Nordenskjold Reinhart DEgmating Munster, GERMANY A process and a system for the purification of waste water in several successive stages includes a first stage for anaerobic treatment of the waste water, a second stage for aerobic treatment of the waste water, a third stage for clarification and sedimentation of the waste water with a sludge return, and an arrangement for controlling the residence time of the waste water in the anaerobic stage by varying the volume of the anaerobic stage.
58Il752 ENHANCEDTUNABLE PLASMA-MELTER VITRIFICATION SYSTEMS Titus Charles H; Surma Jeffrey E Newton Square, PA, UNlTED STATES assigned to Integrated Environmental Technologies LLC The present invention provides tunable waste conversion systems and apparatus which have the advantage of highly robust operation and which provide complete or substantially complete conversion of a wide range of waste streams into useful gas and a stable, nonleachable solid product at a single location with greatly reduced air pollution to meet air quality standards. The systems provide the capability for highly efficient conversion of waste into high quality combustible gas and for high efficiency conversion of the gas
