Aerobic granulation in a mechanical stirred SBR: treatment of low organic loads
Aerobic granular sludge was produced in a sequencing batch reactor (SBR) characterized by a height to diameter ratio of 2.5 and the use of mechanical stirring. Compact and regular aerobic granules of up to 1.75 mm of average diameter were formed in the reactor with an organic loading rate of 1.75 kg COD/(m3 d). Settling properties of the obtained aggregates were: sludge volumetric index of 30–40 ...

A two-sludge system for simultaneous biological C, N and P removal via the nitrite pathway
Nitrogen removal via the nitrite pathway results in significant savings in both aeration costs and COD requirements for denitrification when compared to the conventional biological nitrogen removal process. Implementation of the nitrite pathway for simultaneous C/N/P removal in a single sludge system has a major drawback: the aeration phase disfavours denitrifying phosphorus removal. A possible ...

Advanced nitrogen removal using pilot-scale SBR with intelligent control system built on three layer network
Since eutrophication has become increasingly severe in China, nitrogen and phosphorous have been the concern of wastewater treatment, especially nitrogen removal. The stabilization of the intelligent control system and nitrogen removal efficiency were investigated in a pilot-scale aerobic-anoxic sequencing batch reactor (SBR) with a treatment capacity of 60 m3/d. Characteristic points on the ...

Evaluation of an integrated anaerobic/aerobic SBR system for the treatment of wool dyeing effluents
This work examined the performance of a sequencing batch reactor treating dyeing effluents from a factory that processes mainly wool and wool/polyester blends. Different operational conditions were evaluated, namely the influence of the anaerobic and the subsequent aerobic phase on the organic load removal, as well as the effect of the length of the aeration period (from 8 to 12h) on process ...

Co-treatment of old landfill leachate and municipal wastewater in sequencing batch reactor (SBR): effect of landfill leachate concentration
Sequencing batch reactor (SBR) was assessed for direct co-treatment of old landfill leachate and municipal wastewater for chemical oxygen demand (COD), nutrients and turbidity removal. Nitrogen removal was achieved by sequential nitrification and denitrification under post-anoxic conditions. Initially, SBR operating conditions were optimized by varying hydraulic retention time (HRT) at 20% ...

Acrylic wastewater treatment using SBR technology with aerobic granules
The acrylic or acrylonitrile wastewater treatment were investigated in experimental SBR systems with aerobic granules. The results showed that the diluted acrylic wastewater 400-800 mgL-1 could finally reach a COD removal 71.5-77.5% and a net COD removal 50.5-59.6%. The growth of aerobic granules in reactor was quite slow and retained MLSS 4.6-6.2 gL-1. The pretreatment by internal electrolysis ...
