Abstract
Nitrogen pollution is gathering increased attention due to well-known environmental hazards resulting from overloading of nutrients. Conventional process of nitrogen removal by nitrification and denitrification requires considerable amount of energy and cost for aeration and carbon supply. Several novel and cost-effective biological nitrogen removal processes were developed; however, there were still lots of problems associated with pervious developed reactor systems. In this study application of DHS reactor for nitrogen-removal process could provide the maximum nitrogen-removal efficiency under lower expenditure. The concentrations of nitrogen compounds in this system were maintained below 8 mg N/L in effluent under the nitrogen loading rate of 1.51 kg N/m3-day. In addition, no withdraw sludge was observed in a DHS, decreasing further the cost for post-treatment.
