Practical experiences with start-up and operation of a continuously aerated lab-scale SHARON reactor.
Partial nitrification techniques, such as the continuously aerated SHARON process, have been denoted for quite a while as very promising for improved sustainability of wastewater treatment. Combination of such a SHARON process with the Anammox process, where ammonium is oxidised with nitrite to nitrogen gas under anoxic conditions, leads to cost-efficient and sustainable nitrogen removal from c...
متن کاملControlling the nitrite:ammonium ratio in a SHARON reactor in view of its coupling with an Anammox process.
The combined SHARON-Anammox process for treating wastewater streams with high ammonia load is the focus of this paper. In particular, partial nitritation in the SHARON reactor should be performed to such an extent that a nitrite:ammonium ratio is generated which is optimal for full conversion in an Anammox process. In the simulation studies performed in this contribution, the nitrite:ammonium r...

+ − + + + → + H 2 O H NO O 5 . 1 NH 2 2 2 4 (1) In the SHARON (Single reactor High activity Ammonia Removal Over Nitrite) process, partial nitrification is establishing by working at high temperature (about 35°C) and maintaining an appropriate sludge retention time (SRT). The SHARON reactor is operated as a continuously stirred tank reactor (CSTR, chemostat) without biomass retention, so the sl...
متن کاملFast start-up, performance and microbial community in a pilot-scale anammox reactor seeded with exotic mature granules.
The possibility to introduce the exotic anammox sludge to seed the pilot-scale anammox granular reactor and its fast start-up for treating high nitrogen concentration wastewater were evaluated in this study. The reactor was started up successfully in two weeks; in addition, high nitrogen removal was achieved for a long period. Stoichiometry molar ratios of nitrite conversion and nitrate product...
