Summary A novel Sulfate reduction Autotrophic denitrification and Nitrification Integrated (SAND process has been recently developed by the Hong Kong University of Science and Technology in partnership of Delft University of Technology This novel process can remove COD through sulfate reduction and nitrate through autotrophic denitrification using produced sulfide After a 500 day lab-scale trial we have recently conducted a pilot trial of 10 m(3)/day using de gritted saline sewage in Tung Chung, Hong Kong The SANI pilot plant confirmed the excellent performance of the SANI process achieving 85% removal of both TSS and COD No elemental sulfur accumulated in the plant and no sludge was wasted during the entire trial period of around 210 days The ORP and UVT(254) of the plant effluent were +200 mV and 75%, enabling effective ultraviolet disinfection and a good control of sewage septicity
