A modified ASM1 for nitritation/denitritation for the treatment of sludge reject water in a sequencing batch reactor
A modified ASM1 model was developed to simulate nitritation/denitritation in a sequencing batch reactor (SBR) treating sludge reject water. The model was validated using real data from a pilot SBR. The effect of a number of operating parameters on the nitritation/denitritation efficiency was tested including, among others, the volumetric nitrogen loading rate (vNLR), the solids retention time (...
متن کاملRapid start-up and improvement of granulation in SBR
BACKGROUND The aim of this study is to accelerate and improve aerobic granulation within a Sequencing Batch Reactor (SBR) by cationic polymer addition. METHODS To identify whether the polymer additive is capable of enhancing granule formation, two SBRs (R1 and R2, each 0.15 m in diameter and 2 m in height) are used by feeding synthetic wastewater. The cationic polymer with concentration of 30...
متن کاملStart-Up and Aeration Strategies for a Completely Autotrophic Nitrogen Removal Process in an SBR
The start-up and performance of the completely autotrophic nitrogen removal via nitrite (CANON) process were examined in a sequencing batch reactor (SBR) with intermittent aeration. Initially, partial nitrification was established, and then the DO concentration was lowered further, surplus water in the SBR with high nitrite was replaced with tap water, and continuous aeration mode was turned in...
متن کاملCommunity analysis of ammonia and nitrite oxidizers during start-up of nitritation reactors.
Partial nitrification of ammonium to nitrite under oxic conditions (nitritation) is a critical process for the effective use of alternative nitrogen removal technologies from wastewater. Here we investigated the conditions which promote establishment of a suitable microbial community for performing nitritation when starting from regular sewage sludge. Reactors were operated in duplicate under d...
متن کاملImpact of influent characteristics on a partial nitritation SBR treating high nitrogen loaded wastewater.
The Anammox process allows a sustainable treatment of wastewater with high nitrogen content. Partial oxidation of ammonium to nitrite is a previous and crucial step. Given the variability on wastewater composition, the operation of sequencing batch reactors (SBR) for partial nitritation (PN) is very challenging. This work assessed the combined influence of influent characteristics and process l...
