Elektromosódás

Elektromosódás, also known as electrocoagulation, is a wastewater treatment process that uses direct electrical current to destabilize and remove contaminants. In this method, electrodes are submerged in the wastewater, and when a current is applied, it causes the electrode material to dissolve or oxidize. This released material, often metal ions like iron or aluminum, acts as a coagulant. These metal ions react with dissolved and suspended impurities in the water, forming larger flocs. These flocs then aggregate and can be easily removed through subsequent sedimentation or filtration processes.

The effectiveness of electromosódás depends on several factors, including the type of electrodes used, the current density, the pH of the wastewater, and the nature of the contaminants. It is particularly effective for removing suspended solids, heavy metals, oils, greases, and certain organic pollutants. The process is considered environmentally friendly as it often avoids the need for chemical coagulants, reducing sludge production and the risk of introducing secondary pollutants. It can be applied to a wide range of industrial wastewater, municipal sewage, and agricultural runoff. The energy consumption can be a consideration, but advancements in electrode materials and process optimization are continuously improving its efficiency.
