Total Nitrogen and Total Organic Carbon Analysis by High Temperature Combustion
Abstract Modern High Temperature Combustion (HTC) technology with Chemiluminescence detection (CLD) provides a fast and efficient way to monitor nitrogen loading by Total Nitrogen (TN) analysis. Nitrogen monitoring can be an integral function for the process control of wastewater treatment and other industrial applications, including seawater analysis. Due to the fact that TN analysis can be ...

Degradation rate of anaerobically digested sewage sludge in soil
The objective of this study was to monitor the degradation and obtain the mineralization fraction of anaerobically digested sludge, also known as digestate, under field conditions, when applied to the surface or incorporated into the soil. Sludge was applied to a dystrophic Inceptisol at a dose of 500 kg ha–1 yr–1 of total nitrogen, where the monitoring period of the mineralization process ...

TOC and TN Measurements of Seawater
For pollution control of the ocean and in the research of the ocean environment, the measurement of total organic carbon (TOC) is regarded as an important index of organic contaminants contained in seawater. At the same time, the measurement of total nitrogen (TN), which is known to cause eutrophication, is also attracting attention for environmental pollution control and in ecological ...

Introducing a New ASTM Method for the Determination of Total Nitrogen, and TKN by Calculation, in Water Samples
The USEPA Clean Water Act (CWA) requires national approval for all methods used for CWA compliance. There are approved methods for the determination of inorganic nitrogen (NO3-N, NO2-N, and NH3-N), and for organic nitrogen (TKN – NH3-N)2. There are no EPA approved methods for the determination of total nitrogen although it is a required parameter in many USEPA permits, including monitoring ...

Impact of the As Samra wastewater treatment plant upgrade on the water quality (COD, electrical conductivity, TP, TN) of the Zarqa River
The impact of the As Samra wastewater treatment plant upgrade on the quality of the Zarqa River (ZR) water was investigated. Time series data that extend from October 2005 until December 2009 obtained by a state-of-the-art telemetric monitoring system were analyzed at two monitoring stations located 4 to 5 km downstream of the As Samra effluent confluence with the Zarqa River and about 25 km ...
