The present invention provides a method and apparatus for rapidly extracting the analyte existing in the liquid phase in analyzing an analyte 'having a large partition coefficient in gas-liquid equilibrium', 'having a high water solubility', or &#x201c;having a low olfactory threshold&#x201d; by a gas-liquid contact extraction method, and further provides, a method and apparatus for unmanned continuous sample introduction of the analyte to a GC or the like for a long time. In the present invention, using a gas-liquid contact extractor to which a sample liquid is continuously introduced from above and a purge gas from beneath, the analyte in the sample liquid is extracted by gas-liquid contact between the sample liquid and the purge gas. A discharge pipe is connected to the bottom of the gas-liquid contact extractor, the pipe having a liquid sump through which the sample liquid is discharged, while blocking the outflow of the purge gas from the liquid sump.

Gas-liquid contact extraction method and apparatus

After a running stop command is released, a pump P2 for transferring a solution from the absorber 2 to a regenerator 3 is kept running. The transfer of the solution permits separation of the solution from a refrigerant during non-operation of the refrigerator. The solution saved in the regenerator 3 remains at as a high concentration of the absorbent as that before the end of the operation while the refrigerant is saved in an evaporator 1. This enables the refrigerator to restart its normal operation corresponding to an operation start command.

Method of stopping an absorption refrigerator

An absorption refrigerating/heating apparatus in which a refrigerant vapor generated in the evaporator (1) is absorbed to produce absorption heat by the absorbent in an absorber (2). There are first tube for chilled water in the evaporator, a second tube for cooling water in the absorber, a third tube in an indoor unit (15), and a forth tube in a sensible heat exchanger. The first tube and the second tube are respectively connected to the third tube and the fourth tube in a cooling operation, while to the fourth tube and the third tube respectively in a heating operation.

Absorption refrigerating/heating apparatus

A method for improving the SVI of the mixed liquor residing in an aeration tank in an activated sludge treatment system which also includes a sedimentation tank is provided. This method comprises the following steps:

Method of improving SVI of mixed liquor in aeration tank

A method of sludge concentration comprises forming a froth in the foaming zone by mixing a foaming agent, air and water, mixing the sludge feed with said froth and a polymeric flocculant in a mixing zone, and introducing the resulting mixture of sludge and flocculant into a flotation zone for separating the mixture into a concentrated sludge and water is disclosed.

Sludge concentration method

An activated-sludge process for wastewater treatment comprising the steps of:

Activated-sludge process for wastewater treatment

In the treatment of wastewater by the activated sludge process, mixed liquor in the aeration tank or settled sludge is drawn from the system and concentrated. The concentrated sludge is returned to the aeration tank either immediately or after being mixed with separated water and settled sludge to thereby reduce the SVI of the mixed liquor in the aeration tank.

Method of improving the SVI of mixed liquor in aeration tank

An apparatus for liquid supply in an internal combustion engine having a liquid chamber containing a liquid such as fuel, lubrication oil or the like and located at one side of an intake passage of the internal combustion engine, which liquid chamber is in communication with the intake passage through a delivery passage having a metering throttle interposed therein; and a heating means provided proximately to the throttle portion of the delivery passage.

Apparatus for liquid supply in internal combustion engine

A method and an apparatus of incinerating dewatered sludge without using an auxiliary fuel comprising pelletizing the partially dewatered sludge having a water content of 70 to 75%, drying the pellets with a heat source obtained by burning gases formed by dry-distillation and gasification, using part of the resulting dry-distilled gas in said drying step, dry-distilling the pellets by the sensible heat of a gas formed by gasification, gasifying the dry-distillation residues with air, water vapor and the remainder of said dry-distilled gas.

Method for incinerating sewage sludge

A method for treating excess sludge, which comprises the steps of mixing an inlet stream of waste water with activated sludge, aerating the resulting mixture, separating the effluent water from the activated sludge to be recycled to the mixing step, passing the resulting excess sludge to a conversion stage, treating therein the cells of microorganisms composing suspended solids in said excess sludge to convert them to an organic liquid by a physical and/or physico-chemical means, passing the resulting organic liquid to a digesting stage in which activated sludge takes the organic liquid as a nutrient, aerobically digesting therein the organic liquid and discharging an effluent from the digesting stage.
