SBR technology in Germany - an overview

Abstract

The SBR technology is applied in about 1.3% of the wastewater treatment plants (WWTP) in Germany. This caused the German Association for the Water Environment (ATV) to prepare the guideline ATV-M 210 to represent the state of the art for this type of WWTPs in Germany. The basic design parameters were derived from the standard ATV-A 131 for activated sludge plants to prepare a basis for the comparison of alternatives. In Bavaria numerous small WWTPs utilize SBR technology. Operational experiences show that these plants require specifically trained personnel. The plants produce effluents comparable to those of continuous flow plants in every respect. Hence the choice of system can be based on economic criteria.

Evaluation of municipal wastewater treatment plants with different technologies at Las Rozas, Madrid (Spain)

“…Treatment plants with similar technologies have been installed in Las Rozas, Madrid (Spain). A review showed the generalized application of conventional activated sludge and conventional or compact extended aeration for small-scale plants (Tench, 1994;Berktay and Ellis, 1997;Boller, 1997;Belanche et al, 1999;Tsagarakis et al, 2001;Teichgraber et al, 2001;Lee et al, 2004). The nominal BOD 5 removal efficiencies in these plants are more than 90% when they operate adequately.…”

“…Furthermore, it was found that the rate of purification was limited by lack of oxygen. Teichgraber et al (2001) presented a study of small-scale MWWTPs based on sequential batch reactors (SBR). In addition, operational experiences show that these plants require specially trained personnel.…”

Influence of tetracycline on the microbial community composition and activity of nitrifying biofilms

“…These systems are characterized by having very long SRT and acclimation potential, which may have favoured the degradation process of tetracycline. The SRT in SBBR2 (Teichgräber et al, 2001) was about 21 d.…”

Microbiological and Performance Evaluation of Sequencing Batch Reactor for Textile Wastewater Treatment

“…A sequencing batch reactor (SBR) system is an alternative to conventional systems for treatment of industrial and domestic wastewater. The SBR systems are convenient for organic matter and nutrient removal (Droste, 1997; Teichgraber et al, 2001; ; ). A SBR indicated relatively high performance over conventional suspended growth systems (Cheong and Hansen, 2008; ).…”
