PATENT AB STRACTS
correlation to known fluid flow rates. Pollutants separate in the chromatographic column with a chromatograph being obtained with each injection for identification of pollutants and respective pollution levels. Alternatively, without chromatograph, a single peak is obtained which represents the total quantity of pollutants in the fluid stream. The OLMT enhances sensitivity such that low concentrations can be accurately measured on a continuous basis. The device can further include a sampling valve which samples the fluid stream into the OLMT and then connects the OLMT with a GC carrier gas to avoid incompatible gas flow through the OLMT or the GC detector.

5439590 METHODS FOR TREATING TOXIC MATERIAL Steffan Robert J Newtown Bucks, PA, UNITED STATES assigned to Envirogen Inc The present invention features methods and apparatus for processing waste material held in an aqueous medium. A sorbent is added to the aqueous medium. The sorbent reduces the effective concentration of waste material allowing biodegration of the waste material in solution. A preferred sorbent is rubber derived from ground or shredded tires.

APPARATUS FOR DISSOLVED GAS FLOTATION IN ANAEROBIC W A S T E W A T E R TREATMENT
APPARATUS FOR FAST FERMENTATION TREATMENT
Roshanravan Met Coppell, TX, UNITED STATES assigned to Darling International An apparatus for gas entrainment o f wastewater in an anaerobic wastewater treatment system, the use o f which includes the steps of withdrawing wastewater from an anaerobic digester and piping it into a flotation container. Thereafter the wastewater is pumped into a free standing tank having pressure in the tank maintained at a predetermined level through the injection into the tank of compressed gas generated by anaerobic digestion occurring in the treatment system. The wastewater is removed from the tank and pumped through a multiple jet configuration wherein gas from the tank is entrained in the wastewater as the water is injected back into the tank. The gas entrained water is then discharged from the tank back into the flotation container where the gas bubbles particles to the surface of the water to form a sludge layer. The sludge layer formed on the surface o f the water in the flotation container is recycled to the digester for further increased digestion, thereby providing an efficient flotation process with increased wastewater clarification, reduced disturbance of the anaerobic bacterial sludge layer, and efficient utilization o f the gas generated by anaerobic digestion in the system.
Sayama Takashi Sakai, JAPAN assigned to Martial Plant Corporation An apparatus for fast fermentation treatment rapidly increases the temperature of organic industrial waste to effect fast fermentation at a low running cost. Hot water is circulated inside a rotary shaft of a main body, and a sheath heater is provided on an exterior surface of the main body. Organic industrial waste and ferment bacilli are put into the main body which increases the temperature of the organic industrial waste to about 60 degrees C within one hour using the hot water inside the rotary shaft and the sheath heater. Subsequently, the sheath heater may be operated intermittently or deactivates because natural fermentation heat is generated from the organic industrial waste.
