several laundry houses throughout tehran consume a large amount of water each day and discharge the resulting wastewater into septic tanks or municipal sewage system without any suitable pretreatment. this would result in severe contamination and other serious environmental issues. in the present study, performance of electrocoagulation/flotation process with aluminum and iron electrodes is com...

Background & Aims of the Study: Spent filter backwash water (SFBW) consists of 1-5% of the total treated water typically and it has a high turbidity. Because of the scarcity of water resources and in order to prevent the environmental contamination, effluent treatment of rapid sand filter backwashing is unavoidable. One of the new technologies for removal of turbidity from the ...

Electrocoagulation is a group of various procedures used for removing contaminants from water by electrochemically dissolving aluminum or iron. The contaminants of the solution may be incorporated in the in situ forming metal hydroxide flocs, which can be filtered as a precipitate or skimmed as a float. The main features of the procedure are highlighted on the example of cleaning of an oily was...

Abstract Dug well water is one of the clean sources used in Kubu Raya Regency. However, through initial testing, physical and chemical qualities were inadequate to meet hygiene sanitation demands daily living following Regulation No. 32 Minister Health Indonesia 2017. Consequently, objective this study was examine treatment dug by electrocoagulation electrocoagulation-coagulation employing Poly...

Electrocoagulation (EC) is an electrochemical technique which has been employed in the treatment of various kinds of wastewater. In this work the potential use of EC for the treatment of palm oil mill effluent (POME) was investigated. In a laboratory scale, POME from a factory site in Chumporn Province (Thailand) was subjected to EC using aluminum as electrodes and sodium chloride as supporting...

In the present study electrocoagulation (EC) has been evaluated as a treatment technology for arsenite [As(III)] and arsenate [As(V)] removal from water. Laboratory scale experiments were conducted with three electrode materials namely, iron, aluminum and titanium to assess their efficiency. Arsenic removal obtained was highest with iron electrodes. EC was able to bring down aqueous phase arsen...
