Oxidation-Reduction Potential (ORP) during microbial transformation processes under aerobic, anoxic and anaerobic conditions / Hasnita Ahmad

The sewer is an integral part of the urban wastewater system. The sewer can also acts as a reactor, where the quality of the wastewater is affected by microbial changes during the transportation of the wastewater in the sewer. However, due to the lack of fundamental knowledge in oxidation-reduction...
