Nitrogen　removal　through　the　nitrite　pathway　has　been　successfully　achieved　using　on-line　aeration　length　control.　However,　it　takes　a　long　time　period　to　get　steady　performance　when　using　on-line　control　as　the　sole　strategy.　On　the　other　hand,　salt　inhibition　has　also　been　used　to　achieve　the　nitrite　pathway,　with　potentially　adverse　effects　on　the　overall　microbial　community　at　high　salt　concentrations.　The　objective　of　this　study　is　to　develop　a　control　strategy　based　on　the　combination　of　low　salt　inhibition　levels　and　on-line　control　to　accelerate　the　achievement　of　nitrite　pathway　in　a　sequencing　batch　reactor　(SBR)　treating　domestic　wastewater.　Salt　concentrations　and　on-line　control　parameters　were　chosen　in　batch　tests.　The　recovery　of　the　nitrite-oxidizing　bacteria　(NOB)　activity　was　examined　after　stopping　on-line　control　and　salt　dosing.　The　findings　clearly　show　that　combining　salt　inhibition　at　low　salinity　(5　g/L)　with　on-line　pH　control　is　an　efficient　strategy　to　achieve　nitrogen　removal　via　nitrite　quickly　and　steadily.
