The　principal　aim　of　this　paper　is　to　develop　and　evaluate　an　approach　to　obtain　nitrogen　removal　bypassing　nitrate.　The　method　is　based　on　the　addition　of　sodium　chloride　(NaCl),　selective　inhibitor　of　nitrite　oxidizers,　to　influent.　Validation　of　the　new　method　was　conducted　on　laboratory-scale　experiments　applying　the　SBR　activated　sludge　process　to　domestic　wastewater　with　low　C/N　ratio.　With　the　aerobic　anoxic　sequence,　three　parallel　SBRs　achieving　complete　nitrification　-denitrification　are　dosed　by　a　certain　concentration　of　NaCl　to　influent.　The　high　nitrite　accumulation,　depending　on　the　salinity　in　the　influent　and　the　application　duration　of　salt,　was　obtained　in　SBRs　treating　saline　wastewater.　Optimum　dosage　and　application　duration　of　salt,　which　interact　to　determine　the　performance　and　stabilization　of　nitrite　accumulation,　were　determined　by　experiment.　In　order　to　evaluate　the　method,　the　response　of　the　biological　treatment　system　to　salt　concentration　was　also　explored.　The　repeatability　of　the　method　was　further　verified　under　various　operational　conditions.　Microbial　population　tests　supported　the　presumption　that　nitrite　oxidizers　are　inhibited　by　salt　addition　and　washed　out　of　the　system.　The　presented　method　is　valuable　to　offer　a　solution　to　realize　nitrogen　removal　via　nitrite　under　normal　conditions.
