Results and discussion
Any other information on results incl. tables
85% removal in a municipal waste water treatment plant.
The substance was detected in Swiss waste water treatment plants in a study conducted in 1996. Concentrations in the influent were between <0.03 mg/l to 0.46 mg/l. The highest concentration found was associated with a significant input from the textile industry. An average of 85% removal is observed based on effluent concentrations, for this plant. For the other plants, the substance could not be detected in effluent.
