Determination of H2S in Water and Wastewater


ECH Elektrochemie Halle GmbH

Date: 14:00:00 - Mar 28 2019
Speakers: Karl Robertson, Dr. Michael Hahn, Dorit Wilke
Moderators: Tom Lynch

Detecting and monitoring the formation of H2S is critical to ensure the measurement of acidic corrosion, odour problems and most importantly, the health risks caused by H2S. 

This presentation will show you how H2S can be measured according to the new DIN 38405-27 procedure. Based on a simple gas extraction and electrochemical detection, ECH H2S Analysers are capable of measuring H2S from  0.01 to 10,000 ppm, can analyse up to 40 samples per hour and eliminates all interferences from the sample matrix.   

We will describe in depth how this procedure can be used in different fields: in your laboratory, as a mobile device or, as an on-line controller and how we integrate the analyser not only detect and monitor H2S,  but totally manage the dosing of the treatment chemicals saving our clients an incredible sum of money, who before using the ECH principle, were radically over estimating the amount of treatments solvents used. 

Key learning objectives

  • ECH Principle to DIN 38405-27
  • Automated dosing of the treatment chemicals
  • examples of time and cost savings using the ECH principle
