  • TOC analysis at airports

    As other industrial devices airports have to control their run-off weter for TOC and/or COD. The amount of waste water produced at airports is not negligible: The Frankfurt airport (one of the biggest airports in Europe) has produced 1.63 million cubic meters in 2006, the same amount as a medium-sized city. The sewer system of this airport consists of a 200km tubing system with a low quantity of ...

  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • TOC Analysis: The Best Tool in a Drinking Water Facility`s Toolbox

    Total organic carbon (TOC) has become an important water quality analysis tool for drinking water plants in recent years due to its link to disinfection byproducts (DBPs). TOC alone is not harmful, but upon its reaction with a disinfectant can produce harmful byproducts. However, TOC’s relevance in drinking water ...

  • TOC Analysis for Standard Methods 5310B: High-Temperature Combustion Method

    Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a ...

  • Analysis of Cleaning Validation Compounds using the TOC Fusion Analyzer

    By taking an active approach to prevent cross-contamination in pharmaceutical and cosmetic production, international agencies such as the USFDA, ICH, EC, Health Canada, and the WHO have established regulations and guidelines for effective cleaning and sanitization. With the potential side effects due to exposure, limiting carry-over of residual compounds into subsequent batches is crucial. This ...

  • How TOC analysis relates to disinfection byproducts and the corresponding EPA regulations

    The US Environmental Protection Agency (EPA) amended the Safe Drinking Water Act (SDWA) in 1996 to balance the risks presented by microbial pathogens and by-products from the disinfectant used to destroy these microbes. The byproducts, called Disinfection Byproducts (DBPs), form from the interaction of the naturally occurring organic matter (NOM) in a treatment plant’s source water and its ...

  • TOC Determination in Solid Samples using the Suspension Method

    The TOC content in solids plays an important role in the classification of soils, sludges and sediments. According to the German Ordinance on Environmentally Compatible Storage of Waste from Human Settlements, TOC in solid materials is one of the key parameters for the characterization of wastes as part of the acceptance control of landfills. This important control measure requires a ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process.
