Removal of oil and heavy metals from wastewater sludge using surfactant-enhanced oil removal (SEOR) from plant-based / Nur Amalina Mohd Sulong

Petroleum is the most significant energy source and raw material for the chemical industry. The increasing trends of petroleum industries and the high demand of the production capacity directly leads to the oil pollution generation problems as well as environmental problems which accumulated a la...
