摘要： We describe a system for monitoring effluent discharge to determine one or both of a biochemical oxygen demand (BOD) and a toxicity of the discharge. The system comprises: a culture vessel comprising a sealable chamber for culturing a fluid sample and a pressure measurement transducer for measuring a pressure in a headspace of the chamber; and a data processing system to: input pressure data from the pressure measurement transducer; and determine a value for one or both of BOD and toxicity from the change in pressure measured by the pressure transducer.

摘要： We describe a method of closed-loop control of a waste water treatment plant, the method comprising: obtaining a fluid sample from a fluid of said plant; providing said fluid sample to a sealed chamber such that said fluid sample incompletely fills said sealed chamber leaving a headspace; incubating said fluid sample in said sealed chamber; determining a change in pressure in said headspace during said incubating; and controlling a degree of aeration of said waste water treatment plant responsive to said change in pressure. We also describe a method of measuring one or both of the food content and the biomass content of a fluid of a waste water treatment plant, the method comprising determining a value for one or both of food content and biomass content from a change in pressure.

摘要： We describe a floating respirometer, in particular for monitoring an activated sludge vessel of a sewage treatment plant. The device comprises: a buoyancy device to allow the respirometer to float in an aqueous liquid; a respirometer chamber, supported by the buoyancy device and arranged such that, when the respirometer is floating in said aqueous liquid, said chamber is partially filled with said aqueous liquid and defines an enclosed head space above said aqueous liquid; and a gas sensor in gaseous communication with said head space.

摘要： The invention provides an indirect pressure sensing system for non-invasive measurement of primary pressure in a sealed container, which communicates primary pressure changes from within the container, via a flexible diaphragm, to a secondary chamber wherein there is a defined relationship between the primary and secondary pressures, which enables a pressure sensor in the secondary chamber to generate a signal representing primary pressure in the sealed container, but to remain isolated from the contents of the sealed container. The pressure sensor can provide electrical outputs representing the pressure detected, and the outputs are fed to data processing means capable of producing a measurement of primary pressure. The system can have a liquid culture of cellular material (eg. micro organisms, plant tissue cells, animal cells etc) partially filling the container, whereby the metabolism and/or growth of cellular material causes gas exchanges between liquid and headspace, which can result in primary pressure changes.
