Utilization of Iron Scrap for Palm Oil Mill Effluent Treatment by Fenton and Foto-Fenton Processes

Sains Natural, 2022
The increase in the amount of palm oil production impacts increasing the total liquid waste from the processing of palm oil. Palm oil mill effluent (POME) has high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) parameters that can cause

Chemical oxygen demand (COD) fractionation for process modelling considerations and optimization [PDF]

, 2021
Wastewater treatment is a critical chain in the urban water cycle. Wastewater treatment prevents the toxic contamination of water bodies. The notable consequences of contamination are the loss of aquatic life, upsurge of eutrophication due to nutrient overload, and potential loss of human life as a result of waterborne diseases.
