sähkökoagulaatio
Sähkökoagulaatio, also known as electrocoagulation, is a water treatment process that uses electricity to remove contaminants from water. The process involves passing an electric current through the water, which causes metal electrodes, typically aluminum or iron, to corrode. These corroding electrodes release metal ions into the water, which then act as coagulants. These metal ions neutralize the negative charges of suspended particles, allowing them to aggregate into larger flocs. These flocs can then be more easily removed through sedimentation or filtration.
Electrocoagulation is effective in removing a wide range of contaminants, including suspended solids, heavy metals, oils,
The equipment for electrocoagulation typically consists of an electrolytic cell containing sacrificial electrodes, a power supply,
