Elektrokoagulaation

Elektrokoagulaation, also known as electrocoagulation, is a water treatment process that uses electrical currents to remove contaminants from water. It works by passing an electric current through electrodes submerged in the contaminated water. This current causes the electrodes, typically made of iron or aluminum, to corrode, releasing metal ions. These metal ions then act as coagulants, neutralizing the negative charges of suspended particles, dissolved organic matter, and certain heavy metals. The neutralized contaminants aggregate into larger flocs, which can then be easily removed through sedimentation or filtration. Elektrokoagulaation is effective in treating a wide range of pollutants, including suspended solids, turbidity, color, oils, greases, and heavy metals like lead, copper, and chromium. It is also capable of removing some dissolved organic compounds and bacteria. The process is often favored for its relatively low energy consumption, minimal sludge production compared to chemical coagulation, and its ability to operate over a range of pH levels. It can be implemented in both batch and continuous flow systems and has found applications in industrial wastewater treatment, municipal sewage treatment, and the purification of drinking water. The effectiveness and efficiency of elektrokoagulaation are influenced by factors such as current density, electrode material, water conductivity, and the type and concentration of contaminants.
