Treatment of
wastewater from separators for rainfall runoff using electrochemical oxidation
processes
In recent years, industry has increased and with it the amount of oily wastewater, which are considered hazardous waste because they contain various types of heavy metals and oils that endanger the environment and human health. In the last twenty years, there has been increased research on new technologies to treat wastewater as efficiently and environmentally friendly as possible. A recent approach to wastewater treatment is the application of electrochemical processes such as the electro-Fenton process, which belongs to the group of electrochemical advanced oxidation processes and electrocoagulation. The aim of this work was to remove organic contaminants and heavy metals from wastewater originating from oil and grease separators that clean stormwater runoff from traffic areas. The use of stainless steel, iron and aluminum electrodes results in electrooxidation, electroreduction and electrocoagulation. At a current of 15 A the treatment efficiency was 50% for COD and 73% for mineral oil. At a current of 110 A the treatment efficiency was 96% for COD and 90% for mineral oil.
期刊介绍:
The Environmental & Engineering Geoscience Journal publishes peer-reviewed manuscripts that address issues relating to the interaction of people with hydrologic and geologic systems. Theoretical and applied contributions are appropriate, and the primary criteria for acceptance are scientific and technical merit.
