A full-scale test of a biological nutrients removal system using the sequencing batch reactor activated sludge process

Wastewater treatment has been a challenge throughout the years due to varying influent characteristics and stringent effluent regulations. In response to this dilemma, a reliable, cost-effective and high-efficiency sequencing batch reactor (SBR) technology has been recently developed. SBRs are variations of the activated sludge process that operates on a fill-and-draw basis. It combines both aerobic-anaerobic phases in one unit and saves up to 25% of the aeration costs concomitant with low sludge production. Consequently, simultaneous nitrogen and phosphorus removal from the wastewater could be achieved by adjusting the actual operating cycle. This review paper discusses the technical description and operational flexibility of SBR for the treatment of wide range of effluent under different operational conditions, together with its modifications that could increase the effectiveness of SBR systems in the future.

Sequencing batch reactors (SBRs), due to its operational flexibility and excellent process control possibilities, are being extensively used for the treatment of wastewater which nowadays is fast becoming contaminated with newer and more complex pollutants. It is also possible to include different expanding array of configurations and various operational modifications to meet the effluent limits which are also continuously getting upgraded. This article provides basic description of SBR process along with its functional and physical variants that lead to improved the removal of nutrients and emerging contaminants. The significance of selectors and various recent advancements in the application of SBR has been discussed along with the possibilities held by SBR process in the treatment of wastewater of different origins and composition to produce effluent of reusable quality.
