[Webinar] "TOC and VFA Measurement of Wastewater - Laboratory and Online Analytical Devices"
The measurement of TOC (Total Organic Carbon) is conducted in various situations. The management of TOC in factory wastewater is considered one of the important indicators. Additionally, the measurement of VFA (Volatile Fatty Acids) is one of the key indicators that should be monitored for the stable operation of anaerobic digestion processes, such as methane fermentation and biogas power generation. In this webinar, we will discuss the benefits and case studies obtained from measuring TOC and VFA in wastewater treatment processes, as well as explain laboratory and online devices. ■ Agenda - What is TOC? - Purpose of measuring TOC in factory wastewater - Advantages of laboratory measurements and online measurements - What does it mean to measure VFA in anaerobic treatment processes? - Introduction of TOC analyzers (Online TOC analyzer BioTector and laboratory TOC analyzer QP1680) - Introduction of VFA analyzers (Online VFA analyzer EZ7250) ■ Target Audience - Personnel responsible for measuring TOC and VFA in laboratories or manufacturing sites, - Personnel considering measuring TOC and VFA in the future. * Registration with free email addresses is not allowed. * Participation from other companies in the same industry is discouraged.
