An automated total organic carbon analyzer is described. Embodiments of the system include two features, namely the development of a selective oxidation reactor to oxidize organic contaminants to their corresponding organic acids, and the measurement of the organic acids individually by chain length using an electroanalytical detector. Combining this electroanalytical approach with sequential detection capabilities (such as spectrophotometry) can expand the instrument capabilities by providing organic contaminant speciation. The described reactor performs selective oxidation of organic carbon to organic acids followed by complexation with a proprietary ligand, then selective detection using electroanalytical accumulation and desorption of organic acids performed at an electrode surface.

This disclosure relates to an apparatus and method for analyzing an influence variable on membrane fouling of a seawater desalination system, wherein influence variables other than variables having a low degree of influence, among variables affecting the membrane, are selected, and the influence thereof on membrane fouling is used to derive an equation. The apparatus includes a variable storage unit configured to store variables affecting membrane fouling of a seawater desalination system, a dominant variable selection unit configured to select at least one dominant variable among the variables through at least one algorithm, and an equation derivation unit configured to derive a specific equation based on a correlation between the selected dominant variable and the membrane fouling.

A system includes memory banks that store data and a data path coupled to the memory banks that transfers the data. The system also includes a latch that gates the data path based on a clock signal in the system. The system further includes interface circuitry coupled to the data path that sends an instruction to the memory banks to transmit the data on the data path in response to receiving a first rising edge of the clock signal. The interface circuitry also outputs gated data in response to receiving a second rising edge of the clock signal. The latch gates the data path to store the gated data in response to receiving a falling edge of the clock signal.

A system and method are provided for a food loading station having a disposer that grinds food waste that is located at a facility that processes food waste. A storage tank receives a slurry of food waste and water from the disposer for storage until the slurry is collected for transportation to an anaerobic digestion facility. An agitator is installed in the storage tank for mixing the slurry stored in the storage tank prior to collection for transportation to the anaerobic digestion facility. A discharge outlet is installed on the storage tank for connection to a discharge hose of a collection truck. The discharge outlet has an air admittance valve for admitting ambient air into the discharge hose while the slurry is sucked out of the storage tank through the discharge hose and into the collection truck.

A diaphragm valve includes a valve body including a valve cavity and first and second ports, and a valve assembly disposed to seal the valve cavity. The valve assembly includes a valve seat, a seat carrier and a diaphragm, with the valve seat being retained with said seat carrier and disposed to surround the first port and including a flow passage in fluid communication with the first port. The seat carrier includes an annular body having an outer rim and a web that extends radially inward from the outer rim to a central opening, the central opening being aligned with the first port. The web includes a plurality of flow passages separated by lands about said central opening. Each land has a surface area that is less than a cross-sectional area of said second port so as to reduce obstruction of flow when the land overlays the second port.

The present invention relates to a system and method for containing environmental spills at a zone, for example at a port or rail facility, in order to prevent nm-off water from contaminating the environment. The system and method relates to a water parameter sensor system which is compared to stored contaminants to establish the nature of the contaminant. The system and method further relates to the comparison of the identified contaminant to a manifest database to be able to establish where a spill or leakage may be found.
