    摘要： A water quality sensor comprising a fluorescence sensor arrangement 16 operable to measure a fluorescence intensity, a temperature sensor 22 and a turbidity sensor 24, the outputs of which are used in combination to derive a value for the BOD concentration of a sample, wherein the output of the temperature sensor 22 is used to apply a correction to the sensed fluorescence intensity value using the equation F ref = F mes 1 + ρ  ( T mes - T ref ) where F is the fluorescence intensity signal, T is temperature (° C.), and the subscripts mes and ref represent the measured and reference values respectively, and ρ is a temperature compensation coefficient.

    摘要： Embodiments of the present invention relate to a method of detecting, identifying, and quantifying microbes in a wastewater treatment process or facility. The invention identifies the microbes by manipulation of their DNA. Microbes are collected, and a portion of the DNA sequence of a particular gene that is found in microbes is amplified. The amplified DNA sequence contains a highly variable region that can be used identify the microbe. Each amplified DNA sequence is matched against known sequences in various microbes. The identity of the microbes present in a sample can be determined and, sometimes, their biological functions too. Also, the relative quantities of the microbes, compared to the total microbial pool, can be determined. With this information, harmful microbes can be identified and targeted for removal from the wastewater, and beneficial microbes can be cultivated as desired.

    摘要： Disclosed is a wastewater monitoring device comprising, a selectively sealable chamber; a first oxygen sensor, operable to measure the level of oxygen dissolved in a liquid; said first oxygen sensor being locatable inside of the sealed sealable chamber; and a second oxygen sensor, operable to measure the level of oxygen dissolved in the wastewater being tested. The selectively sealable chamber may be defined by a shell member and a piston member, the piston being locatable inside the shell member so as to define said chamber. At least one of the shell member and piston member may be actuatable linearly relative to the other so as to selectively seal the chamber.

    摘要： Embodiments of a dissolved oxygen sensor are disclosed herein. Embodiments as disclosed herein may include a window of optically transparent material disposed in an opening in a fluid flow path, where a luminophor is attached to the side of the window exposed to the fluid in the flow path. An optical probe may be disposed opposite the window from the fluid flow path on an axis at an angle to the window fluid flow path. The optical probe includes an excitation light source for illumination of the luminophor and a reference light source. An optical reception guide is configured to conduct light from the luminophor to a photodiode adjacent to the end of the optical reception guide distal the window when the luminophor is illuminated by the excitation light source. The optical probe is configured to determine a measure of oxygen concentration of the fluid in the flow path. The optical reception guide and photodiode may be aligned on axis, where the axis may be substantially parallel with the axis on which the optical probe is aligned.
