  • Operating Open Cooling Systems in a Hygienic Manner
    The VDI 2047 Part 2 Guideline "Open recooler systems - Securing hygienically sound operation of evaporative cooling systems" forms the basis of national guidelines throughout Europe, e.g. the German 42nd Federal Immission Prevention Directive (42. BImSchV). It contains details on continuous water treatment, disinfection, and regular checks on microbiological, chemical and electrochemical parameters.
    This comprehensive document provides background information and provides an overview of analytical solutions for the parameters that need to be monitored by operators.

  • Monitoring Influent Toxicity to Mitigate Risk and Optimise Treatment 
    Influent toxicity represents a major risk to the treatment efficiency and therefore capacity of biological wastewater treatment plants. The Hach® EZ7900 Toxicity Analyser, with self-cleaning sample preconditioning panel, provides the ability to continuously monitor toxicity levels at the inlet, so that dynamic changes in biomass viability are immediately detected; providing sufficient time for effective mitigation measures.

  • Toxicity Monitoring at the Inlet of Wastewater Treatment Plants 
    Whitepaper about Toxicity Monitoring with EZ7900 Toxicity Analyser; Presented at CITREI 2020 Wastewater Congress, Lima, Peru
    English   DOC_30671, 6 pages
  • Volatile Fatty Acids (VFA) and Alkalinity for Optimal Operation – Anaerobic Digestion and Gas Production
    pH is not enough. A sustainable safe fermentation process depends on the buffer capacity to counterbalance changing concentrations in organic acids. The VFA:Alkalinity ratio provides the most reliable insights to fermenter conditions.

  • Anaerobic Digester Monitoring Helps Avoid Process Upsets and Maximise Biogas Production
    Medina County Sanitary Engineers supports the public utilities serving the city of Medina, Brunswick (USA), and several other townships. The county maintains three water reclamation facilities. At one of these, the county funded upgrades to increase renewable energy capture from their anaerobic digester system. Medina County installed the EZ7250 Volatile Fatty Acids (VFA) analyser to monitor their process better, help prevent process upsets and maximise biogas production.

  • Volatile Fatty Acids (VFA) in Anaerobic Digesters
    The Swedish Municipal Joint Stock Company VIVAB tested the analyser to assess the functionality and maintenance of the analyser and the reliability of its measurements related to VFA, alkalinity, and pH. Further aims of the testing were to improve the understanding of anaerobic digestion and the active return sludge process (ARP), and to identify the optimisation potential of these processes. The analyser was subjected to stress tests at different sites. Three different laboratory methods were used to determine the VFA values and the alkalinity of the samples, after which the values obtained, were compared with the online measurements of the analyser.
    This is a summary of the original 28+ page report. The tested AnaSense is the same as the Hach EZ7200 VFA Analyser.
