The addition of the new air sampling integration means you are able to detect key environmental pollutants, including gases such as carbon monoxide, carbon dioxide, nitrogen dioxide and nitrate. The air quality sensor can detect particulates, too, including respirable particles with sizes PM 1, PM 2.5 and PM 10. ...
Smart water management requires reliable and quick detection of nitrates to allow water utilities to take rapid action and protect public health against the hazards posed by nitrates. Online nitrate detection would particularly be beneficial for treatment facilities withdrawing their waters from sources ...
Continuous monitoring of nitrate enables you to keep a real-time pulse on nitrate concentrations from source water to finished water, offering many benefits: Compliance with drinking water standards for nitrate Optimized blending ratios to maximize water use Efficient nitrate treatment with ion exchange or reverse osmosis ...
In modern agricultural planting, people often use a variety of advanced instruments and equipment to detect the various conditions of soil information. And the appearance of portable soil sensor, so that people can detect the content of various substances in the soil anytime and anywhere. ...

At two points on the six stages in the plant's nitrification reactors, the analyzers automatically draw samples and then analyze them for nitrate and ammonia.The ChemScan Online Analyzers use fully automated ultraviolet‐visible spectrometry to measure absorbance levels across 256 wavelengths of light. A single process analyzer can monitor up to eight sample points, separately ...
A single process analyzer can monitor up to eight sample points, separately detecting ammonia, nitrite and nitrate from multiple process sample points or basins. ...
Samples are automatically drawn at the two weirs where the sludge exits to the clarifiers and the analyzer tests them for levels of Nitrates (NO3) and Ammonia (NH3). Depending on the results, the analyzer sends control signals via the SCADA to either increase or decrease the speed of the surface aerators. ...
Negative health outcomes from nitrate in drinking water hit farming communities particularly hard A new Environmental Working Group (EWG) study, published inEnvironmental Research, has estimated that nitrate contamination of drinking water will cause thousands of cancer cases annually in the United States. ...
In 2010, the award winning treatment facility initiated a new program to further improve its treated effluent by removing nitrate concentrations to very low level. As part of the initiative, ARoNite process consistently removed effluent nitrate concentrations below the detectable limit of 0.5 mg-N/L. ...
Solution ASA Analytics supplied a centralized nutrient analysis system for CaRRB improvements in 2009, following a two year period of development, testing, project design and procurement- The system uses a single ChemScan UV-6101 Analyzer and four in-line cyclic filters to monitor Nitrate and Ammonia from four sample locations within the plant. One of the major benefits of this ...
"The online analyzers are used to monitor orthophosphate, ammonia, nitrite, and nitrates, and they literally run the plant by telling the programmable logic controller, or PLCs, when and how fast to run the blowers and how to adjust the valves to keep the process in compliance for total nitrogen." ...
Metabolite analysis revealed that parathion and MP were hydrolysed to p-Nitrophenol (PNP). Additionally, nitrate and sulphate were detected during the biofilter operation. The biofilter performance and microbial community were also assessed and characterised.Keywords: waste gas treatment, biofilters, genetically engineered microorganisms, organophosphorus ...
At two points on the six stages in the plant's nitrification reactors, they automatically draw samples and then analyze them for nitrate and ammonia. "Online monitoring has removed the guesswork from optimizing our nitrification and denitrification processes," said Robert Decker, operations specialist. ...
Nitrifying bacteria consume excess ammonia nitrogen (NH3-N) producing nitrite (NO2) and nitrate (NO3). In theory, reactor nitrate residuals should be stable if the reactor is not anoxic. When nitrate residuals are elevated secondary clarifier denitrification may occur. ...
