A cleaning system and method remove localized caked or dewatered solids from flat-plate membranes in a sewage treatment plant. The caked sludge on the membranes is removed by intense coherent water sprays directed into the spaces between cartridges of a cassette, without removing the cartridges from the cassette. The sprays can be delivered from the top and/or bottom of the cassette, or the side panels of a cassette can be removed for spraying from at least one side, preferably both sides, using a mechanical device with movable spray bars and motor-driven advancing of the spray bars. In one preferred form of the system the apparatus includes horizontal cutting jets followed by angled cutting jets that further break up and wash away the loosened sludge. Jet diameter, velocity and pressure are controlled so as not to damage the membranes or cartridges but to achieve efficient cleaning.

In accordance with at least one exemplary embodiment, a syringe, method and system for delivering a therapeutic amount of ozone are disclosed. An exemplary syringe can have a gas chamber and one or more electrodes. A portion of at least one electrode can be within the gas chamber. Alternatively, singularly or in conjunction, one or both electrodes can be attached to the outside of an exemplary syringe. One or more electrical contact points can be outside the gas chamber. Each electrical contact point can be connected to an electrode. Oxygen gas can provided within the gas chamber of the exemplary syringe. A medical ozone generator can be connected to the syringe via the electrical contact points. Corona discharge can be effectuated via the electrodes, which can result in an amount of ozone gas can being produced from the oxygen gas.

An optical analysis flow system and a method of assay analysis includes a means for facilitating activation of a luminescent material coupled to particles entrained within a fluid assay, wherein the means is arranged such that the activation of the luminescent material is conducted at a site along a flow path of the fluid assay prior to an examination zone of the optical analysis flow system. The method further includes measuring luminescent light emitting from the particles as they flow through the examination zone. Another method of assay analysis includes respectively measuring different types of luminescent light emission from a first set and a second set of particles comprising a fluid assay. An optical analysis system includes at least two distinct means for respectively facilitating the activation of at least two different luminescent materials coupled to particles of a fluid assay.

The present disclosure relates to sample processing device and associated methods of use. The sample processing device includes an internal chassis comprising one or more receiving chamber and one or more corresponding rows of buffer chambers operable to store a buffer liquid. The device also includes an external chassis having an actuator that is operable to actuate a piston. The piston is in turn operable to sequentially engage each buffer chamber of each row of buffer chambers as the internal chassis moves through a series of index positions relative to the external chassis. When actuated, the piston causes the dispensation of fluid from the underlying buffer chambers to the corresponding receiving chambers. A valve is coupled to the internal chassis and operable to sequentially provide a fluid coupling between the respective receiving chambers and each buffer chamber of the corresponding rows of buffer chambers. The device also includes a lever that is operable to move the internal chassis relative to the external chassis though a plurality of index positions in response to the actuator being activated.

A sample processing device includes a receiving chamber having a chamber inlet and a chamber outlet. The processing device also includes a metering portion having a metering reservoir fluidly coupled to the chamber outlet, and at least one vessel fluidly coupled to the metering reservoir by a syphon. The syphon is operable to actuate upon a preselected volume of liquid being received at the metering reservoir. The syphon includes a syphon inlet and a syphon outlet, with the syphon outlet being fluidly coupled to the vessel. The preselected volume of liquid corresponds to a volume of liquid necessary to deliver a metered volume of fluid to the vessel.

A specimen processing cartridge includes a first fluid source operable to deliver a first liquid to a first flow path and to transmit the first liquid to a testing area. The cartridge also includes a second fluid source operable to deliver a second liquid to a second flow path and a bridging member positioned between the first flow path and second flow path. The bridging member is operable to receive the second liquid from the second fluid source, and to deform from a first position to a second position upon receiving the second liquid. When not deformed, the bridging member does not contact the first flow path. When deformed, however, the bridging member contacts the first flow path and is operable to transmit the second liquid to the first flow path upon contact.
