<span style=" font-family:'Courier New'; font-size: 9pt;">Hello Listers and Dominic,<br>
<br>
Methanogens are considered to be rather sensitive to toxic materials and chlorine is seen as being very toxic to them. Any organic compound that contains chlorine is therefore likely to cause problems in anaerobic digesters. The three you listed contain large amounts of chlorine. Biomass does contain small amounts of sodium and potassium, which will neutralize chlorine, so small amounts may be tolerated. However, any quantity of these chemicals are likely to stop the plant working. <br>

In an article by Barbara Klingler of the German Biogas Association, it is mentioned that :<br>
“Organic compounds can be reduced through the anaerobic treatment processe.”<br>
Then she listed a certain amount of organic compounds such as : TRichlormethane, dichloromethane and tetrachlormethane and others.<br>
I would like to know more about that.<br>
<br>
Thank you in advance,<br>
