2. Electrocoagulation - Wikipedia

   en.wikipedia.org/wiki/Electrocoagulation

   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 ...

3. Wastewater treatment - Wikipedia

   en.wikipedia.org/wiki/Wastewater_treatment

   Wastewater treatment. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it.

4. Coagulation (water treatment) - Wikipedia
