Electro-oxidation (EO or EOx), also known as anodic oxidation or electrochemical oxidation (EC), is a technique used for wastewater treatment, mainly for industrial effluents, and is a type of advanced oxidation process (AOP). [1] The most general layout comprises two electrodes, operating as anode and cathode, connected to a power source.
Electrocoagulation (EC) is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum ...
The electrochemical carbon nanotubes can be easily used for removing amino group based dyes from wastewater. Chen etal first reported the absorption of dyes to the CNT walls by strong covalent bonds. These electrochemical CNT can be typically used for filtering, and recycling wastewater.
The AOP procedure is particularly useful for cleaning biologically toxic or non-degradable materials such as aromatics, pesticides, petroleum constituents, and volatile organic compounds in wastewater. [5] Additionally, AOPs can be used to treat effluent of secondary treated wastewater which is then called tertiary treatment. [6]
Water reuse (e.g., desalination brine treatment, industrial laundry wastewater, produced water from oil/gas production, cooling tower makeup & blowdown, metals industry fluids, wash-rack water) Pre-demineralization (e.g., boiler makeup & pretreatment, ultrapure water pretreatment, process water desalination, power generation , semiconductor ...
MFCs in wastewater treatment, besides electricity generation, also help in energy savings linked to these mentioned processes which add a great advantage. The MFC process is an anaerobic process and sludge production for an anaerobic process is approximately 1/5 of that for an aerobic process.
A well-known electrosynthesis is the Kolbe electrolysis, in which two carboxylic acids decarboxylate, and the remaining structures bond together:; A variation is called the non-Kolbe reaction when a heteroatom (nitrogen or oxygen) is present at the α-position.
Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically ...
