PILOT PLANT FOR TREATMENT OF RAW DRINKING WATER WITH HIGH CONTENT OF ARSENIC USING FERRATE (VI)

The paper presents the results of treatment of raw drinking water, loaded with organic substances (COD = 94.68 mg / l) and high concentration of As (up to 38.66 mg / l). The treatment of raw water was carried out by in situ electrochemically synthesized ferrate(VI) in a pilot plant with a flow-throu...

Summary:The paper presents the results of treatment of raw drinking water, loaded with organic substances (COD = 94.68 mg / l) and high concentration of As (up to 38.66 mg / l). The treatment of raw water was carried out by in situ electrochemically synthesized ferrate(VI) in a pilot plant with a flow-through electrochemical cell. For the treatment of water the pilot plant batch type with three reaction columns was formed. The developed method was applied to the treatment of raw water from four different sources. The results showed the removal of up to 97% As, and permanganate index close to the statutory limit value (12 mg / l of KMnO4).
