Compared with market-leading UV-based nitrate analysers, Aquamonitrix offers a key advantage in statutory limit monitoring applications at the outlet of drinking water treatment plants. In addition to providing high-accuracy, real-time nitrate monitoring, Aquamonitrix simultaneously provides a specific, high accuracy real-time nitrite measurement, with a lower limit of detection of just 0.05 ...
Real-time continuous online measurement system for ammonia Low Initial Procurement Cost compared to competing technologies and offerings No need for chemical feed and rebuilding of sensors Lower Cost of Ownership due to very long sensor lifetime, low maintenance & cleaning requirements for inline, immersion & submersion ion selective sensors Intuitive and easy to use TT-MA analyser ...
Initial benchmarking consisted of visual soil assessment and a full soil analysis, which was repeated at the end of each year. As any good agricultural scientist will tell you, basing fertiliser decisions on nitrate nitrogen in a soil analysis is wrought with problems due to seasonal variation. ...
New generation of UV Nitrate Sensors Nutrient monitoring is becoming more important as time goes on – as human activity increases the natural amount of nitrate in water, plants and organisms are more and more negatively affected. Current nutrient monitoring relies on low temporal frequency monitoring and spot-checking, which are vulnerable to uncertainties and less representative of the ...
The logistic regression model showed that nitrate was statistically significant in predicting increasing risk of cancer when potential confounders were kept at base level (P value of 0.001 nitrate in drinking water; 0.003 for nitrate in vegetable) at P < 0.01. Exposure to nitrate in drinking water at >45 mg/L level of ...
Fly ash is a by-product of the combustion of pulverized coal and is composed of small particles. The composition of the fly ash may vary considerably, however, all fly ashes contain substantial amounts of silicon dioxide (SiO2), aluminum oxide (Al2O3) and calcium oxide (CaO). Nowadays, air pollution control standards require a separation of flue gas before being released to the atmosphere. Fly ...

Nitrogen is naturally found in groundwater and surface water in the form of nitrate, nitrite, or ammonium. The EPA has established a maximum contaminant level of nitrate-nitrogen in potable water of 10ppm. This application presents results of UV-Vis analysis of nitrate concentrations in drinking water, ground water, and ...
The sections of the Knowledge Center include: Fluid Types Oil Hydraulic fluid Fuel Biofuels Coolant Analytical Techniques RDE Optical Emission Spectroscopy Particle Analysis Ferrous Monitoring Viscosity Infrared Spectroscopy X-ray Fluorescence Surface Acoustic Wave Test Parameters Wear Particle count, size, composition Ferrous wear Elemental ...
Locally manufactured ceramic water filters are one effective household drinking water treatment technology. During manufacturing, silver nanoparticles or silver nitrate are applied to prevent microbiological growth within the filter and increase bacterial removal efficacy. Currently, there is no recommendation for manufacturers to test silver concentrations of application solutions or ...
Removal of total cyanide was determined using the silver nitrate titration method. Regression analysis and optimization of the conditions were conducted using the Design-Expert software and response surface methodology (RSM). The actual cyanide removals and the removals predicted using RSM analysis were in close agreement, and the optimal ...
The dual isotope approach using the stable isotope ratios of nitrate nitrogen (δ15NNO3) and oxygen (δ18ONO3) is a strong tool for identifying the history of nitrate in various environments. Basically, a rapid procedure for determining δ15NNO3 and δ18ONO3 values is required to analyze many more samples quickly and thus save on the operational costs of isotope-ratio mass spectrometry (IRMS). We ...
Abstract Surface decontamination efficacy determination of DeconGel™ 1101 on stainless steel, carbon steel, and concrete surfaces contaminated with nickel nitrate (Ni(N03)2) was performed with ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) according to Environmental Protection Agency (EPA) SW-846 Methods: 3005A (sampling) and 6010C ...
Many studies have been conducted to investigate the factors affecting nitrate load in surface and subsurface flow. The objective of this study is to investigate the relationship between the various factors affecting nitrate transport using principal component analysis (PCA) and nearest neighborhood analysis methods. ...
The focus of this study was to assess the treatment performance and granule progression over time within a continuous flow reactor. A continuous flow airlift reactor was seeded with aerobic granules from a laboratory scale sequencing batch reactor (SBR) and fed with dairy wastewater. Stereomicroscopic investigations showed that the granules maintained their integrity during the experimental ...
Chemical parameters including salinity, chloride, calcium, alkalinity and total hardness were determined using titrimetry method. Sulphate and nitrate were determined by spectrophotometer while magnesium was determined by atomic absorption spectrophotometer. Results of the functional linear relationship of the parameters show that electrical conductivity and salinity have a ...
This study uses a high-frequency discharge and nitrate concentration dataset from the Weida catchment in Germany for the catchment scale hydrologic response analysis. Nitrate transport in the catchment is mostly conservative as indicated by the nitrate stable isotope (δ15N and δ18O) analysis. ...
This study investigated the effect of PP-g-AA-AM non-woven fabric on the removal of nitrate nitrogen from groundwater. The breakthrough time was 1.5–2.6, 2.5–5.5, and 6.2–12.2 h for a superficial velocity of 2.0, 1.0, and 0.5 cm/s, respectively, for the nitrate nitrogen concentration in groundwater to satisfy the safe standard for drinking ...
However, nitrite accumulation had been observed for 140 days before attaining complete nitrification to nitrate. Fluorescence in situ hybridization analysis revealed the increase in amount of ammonia-oxidizing bacteria which existed in the outer edge of the granular sludge during the start-up period. ...
