Abstract
current density, which resulted in 95.59% nitrate nitrogen, 97.56% ammonia nitrogen, and 96.74% orthophosphate for the Al-Al electrode; 96.08% nitrate nitrogen, 98.54% ammonia nitrogen, and 97.78% orthophosphate for the Fe-Fe electrode; and 95.83% nitrate nitrogen, 98.05% ammonia nitrogen, and 97.31% orthophosphate for the Al-Fe electrode, respectively. This means that when current density increases and operating time increases, then the pollutant removal efficiency of electrocoagulation technology becomes high performance. The results showed that electrocoagulation technology using an iron electrode is an effective method for removing nutrients from municipal wastewater. The study findings contribute to an integrated electrode offering a viable route to more economical, sustainable and effective nitrogen removal from municipal wastewater, which would ultimately improve water quality and save the environment.
