As an organic compound, toxic to animal and human kinds once ingested, a regular organic pollutant in some industrial wastewater which will enhance chemical and biological oxygen demand in water, electro-oxidation is one of the most efficient approach to remove ethylene glycol.
What Are The Uses of Ethylene Glycol
Ethylene glycol is one of the basic components in antifreeze and coolant automotive antifreeze and coolant, to preventing internal combustion engines of automotives, HVAC equipment and systems, solar heating equipments from freezing in cold temperatures and overheating in higher temperatures, some 25 percent of ethylene glycols are for this application.
And then de-icing solutions for aircraft and runways in airports.
Some 36 percent of ethylene glycols are utilized to manufacture PET solid-state resins, some 24% for polyester fibers production, 4% for polyester film fabrication, 3% in PET chip resin exports, and some 8% utilized in surface coatings, polyester and alkyd resins, chemical intermediates, and other miscellaneous industrial applications.
Ethylene Glycol In Water
Actually sources of Ethylene glycol in water bodies and wastewater can be tracked back to the actual applications of this type of organic compound, and this allow people to analyze the relevant solutions to tackle the harsh problems and challenges faced with ethylene glycols.
Manufacturing, transportations, and recycling of antifreeze and coolant attribute a significant amount of pollutation to the water bodies.
De-icing operation solutions at the airports bring huge amount of ethylene glycol to the sewage and underground water systems.
Other sources are polyester fibers, polyester film, surface coatings, polyester and alkyd resins, chemical intermediates manufacturing activities.
How To Remove Ethylene Glycol From Water
Electro oxidation is an innovative approach to, not just degrade, but to remove ethylene glycols complete from the water sources.
Electro oxidation process decompose ethylene glycols in water via two major mechanisms:
The first approach is direc oxidation of ethylene glycol molecules, that is direct electron transfers among the anode and ethylene glycol, adsorbed on the anode surface and widely spreaded within the solutions, these ethylene glycol molecules can be transfromed into different compounds, they variate as the quantity of the exact quantity of electrons transferred during this process. Indirect oxidation of ethylene glycol involves electro-generation of reactive oxygen species, for instance, hydroxyl radicals (·OH ), a potent oxidant with high electrochemical oxidation capability, they mineralize ethylene glycols into intermediates and simple compounds right away in an indiscriminate way.
Ethylene Glycol Removal From Wastewater Via Innovative Electro Oxidation Treatment Technologies
In this section, we will explain how electro oxidation wastewater treatment approaches remove ethylene glycol from waste streams, main content will be about the direct oxidation by transferring electrons, and oxidizing agents for indirect oxidation.
Anode material
Boron doped diamond electrode has the widest potential window, way lower background current, stability & biocompatibility, optimized boron doped diamond elelctrode could expedite direct and indirect oxidation of reclatriant organic pollutant.
Efficiency
Unlike regular electrodes with shorter lifespan, boron doped diamond electrode is highly stable, resistant to acid and alkali electrolytes, less chance of fouling, bulk generation of oxidants such as hydroxyl radicals, with a higher oxidation capability in the organic pollutant removal processes.
Eco-friendly
Unlike regular advanced oxidation processes, the electrochemical advanced oxidation via the boron doped diamond electrode does not require addition of toxic chemicals, most types of organic pollutants and their intermediates could be oxidized into inorganic carbons and water.
