Effects of granular activated carbon on membrane fouling in anaerobic membrane bioreactors

Anaerobic membrane bioreactors may be viable options in the treatment of various wastewaters. The major drawback of the widespread adoption of such technology is membrane fouling. Carbon dosing has been found to be an effective method in the control of fouling. In this study, it was found that the...
