ELECTROCOAGULATION Meaning and
Definition
-
Electrocoagulation is a process that involves the use of an electrical current to treat or remove contaminants in water or wastewater. It is a type of electrochemical treatment method that relies on the principles of coagulation and flocculation.
In electrocoagulation, two or more metallic electrodes are immersed in the water or wastewater to be treated. When an electric current is applied, the electrodes release metal ions, usually aluminum or iron, into the solution. These metal ions form hydroxide precipitates, which act as coagulants. The coagulants are responsible for destabilizing and aggregating suspended particles, colloids, and dissolved substances in the water.
During the process, the destabilized particles form larger flocs, which can be easily separated from the water through sedimentation or flotation. Electrocoagulation can effectively remove contaminants such as heavy metals, suspended solids, oil, grease, organic compounds, and even pathogens from water.
The advantages of electrocoagulation include its ability to operate at ambient temperatures, its relative simplicity, and the fact that it does not require the addition of chemical coagulants. Additionally, it can be easily scaled up or down depending on the volume of water to be treated.
However, electrocoagulation also has some limitations, including the generation of sludge that must be properly disposed of and the potential for electrode passivation if the process is not carefully controlled.
Overall, electrocoagulation is a valuable water treatment process that can be employed in various industries, including wastewater treatment plants, textile manufacturing, mining, and food processing.

Etymology of ELECTROCOAGULATION
The word "electrocoagulation" is a compound word derived from the combination of two elements: "electro-" and "coagulation".
1. "Electro-" is a prefix derived from the Greek word "ēlektron", which means "amber" or "electricity". It is often used in English to signify an association with electricity or electric currents.
2. "Coagulation" comes from the Latin word "coagulatio", which means "the curdling or clotting of a liquid". In medical and scientific contexts, it refers to the process of clotting or turning a liquid into a semi-solid or solid state.
Therefore, "electrocoagulation" refers to a process or technique that involves the use of electricity or electric currents to cause coagulation or the solidification of a liquid substance. It is commonly used in various fields, including medicine, wastewater treatment, and industrial processes.
