Trials of Treating Decentralized Domestic Sewage from a Residential Area by Potassium Ferrate(VI)

Trials of Treating Decentralized Domestic Sewage from a Residential Area by Potassium Ferrate(VI) The present study aims to investigate the performance of potassium ferrate(VI) in treating decentralized domestic sewage from a rural scattered residential area. Major results were that around 90% of total phosphorus (TP) and 40% of chemical oxygen demand (COD) could be reduced when 25 mg L−1 of ferrate(VI) was applied. The removal of ammonia and total nitrogen (NH3–N and TN) was also monitored. However, the nitrogen removal during the chemical dosing was rather low. Big fluctuations of removal rates were observed against shock pollutants concentrations. Considering its strong ability in removing emerging organic pollutants and P, ferrate(VI) is competitive in the treatment of decentralized domestic sewage as an advanced treatment unit following some traditional treatment units. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Water, Air, Soil Pollution Springer Journals

Abstract

The present study aims to investigate the performance of potassium ferrate(VI) in treating decentralized domestic sewage from a rural scattered residential area. Major results were that around 90% of total phosphorus (TP) and 40% of chemical oxygen demand (COD) could be reduced when 25 mg L−1 of ferrate(VI) was applied. The removal of ammonia and total nitrogen (NH3–N and TN) was also monitored. However, the nitrogen removal during the chemical dosing was rather low. Big fluctuations of removal rates were observed against shock pollutants concentrations. Considering its strong ability in removing emerging organic pollutants and P, ferrate(VI) is competitive in the treatment of decentralized domestic sewage as an advanced treatment unit following some traditional treatment units.
