Book excerpt: The sequencing batch reactor (SBR) is perhaps the most promising and viable of the proposed activated sludge modifications today for the removal of organic carbon and nutrients. In a relatively short period, it has become increasingly popular for the treatment of domestic and industrial wastewaters, as an effective biological treatment system due to its simplicity and flexibility of operation. Mechanism and Design of Sequencing Batch Reactors for Nutrient Removal has been prepared with the main objective to provide a unified design approach for SBR systems, primarily based on relevant process stoichiometry. Specific emphasis has been placed upon the fact that such a unified design approach is also by nature the determining factor for the selection of the most appropriate cyclic operation scheme, the sequence of necessary phases and filling patterns for the particular application. The proposed basis for design is developed and presented in a stepwise approach to cover both organic carbon and nutrient removal, domestic and industrial wastewaters, strong and specific wastes. The merits of model simulation as an integral complement of process design, along with performance evaluation of SBR models are also emphasized. Scientific and Technical Report No. 19

Available in PDF, EPUB and Kindle. Book excerpt: The practical guide on what to do right when biological influences cause a sequencing batch reactor to go wrong This richly illustrated, straightforward guide carries forth the legacy established by previous editions in the Wiley Wastewater Microbiology series by focusing attention on the mixed gathering of organisms cohabitating within a sequencing batching reactor (SBR), and the key roles their biology plays in this wastewater processing tank's function. With a clear, user-friendly presentation of complex subject matter, Troubleshooting the Sequence Batch Reactor first teaches plant operators how to differentiate the positive and expected organismal dynamics present in optimal SBR performance from the negative and damaging ones that create unhealthy sludge, and a stoppage in SBR operations. Next, Troubleshooting the Sequence Batch Reactor delivers all the tools necessary to get an SBR back on track and running safely. In this book you'll get: Short-course situations tested by the author for the past fifteen years Accessible material aimed at operators instead of design and consulting engineers Essential information for understanding biological conditions such as aerobic, anoxic, and anaerobic/fermentative at the treatment process Examination of the properties of protozoa (single-celled) and metazoa (multi-celled) organisms, and their significance in wastewater treatment Devoid of overwhelming scientific jargon, chemical equations, and kinetics, this book simplifies details to provide quick instruction for plant operators on how to make more informed day-to-day process control decisions, how to troubleshoot confidently when SBR conditions become compromised, and how to act decisively when the problem is ultimately identified.
Download or read book Enhancement of Nutrient Removal in SBR Systems Through Acid Fermentation of Raw Wastewater written by and published by . This book was released on 1903 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid fermentation of degritted raw wastewater was investigated using a sequencing batch mode of operation. The conditions of the experiments included sludge retention times of 4, 8 and 13 days, influent pH ranges of 7.0-7.6 and 6.1-6.4, mixing periods of 6 h/cycle and 0.25 h/cycle, and hydraulic retention time of 12 h, 9 h, and 6 h. The impact of prefermentation of raw wastewater on enhancement of nutrient removal in SBR systems was explored in conjunction with the fermentation process. This was done by developing a two-stage anaerobic-aerobic SBR system (PAF-SBR) in which the wastewater was first fermented in a sequencing batch reactor named PAF (Primary Acid Fermenter). The effluent from the fermenter was conducted to another SBR for carbon, nitrogen and phosphorus removal. The performance of this system was evaluated against a parallel conventional-SBR. All experiments were carried out at room temperature (20 $\pm$ 2$\sp\circ$C). It was found that acid fermentation of degritted raw wastewater is a stablereliable process. Acetic acid was the main component (78-96%) of volatile fatty acids (VFA) produced under the various investigated conditions. Sludge retention time (SRT) had a pronounced impact on the solubilization of organic matter and production of VFA. Both processes improved as SRT increased from 4 d to 13 d. Overall efficiency of VFA production diminished as the influent pH range was reduced from its natural range of 7.0-7.6 to the range of 6.1-6.4. Influent pH also affected VFA distribution. Acetic acid production was reduced at the pH range of 6.1-6.4, while production of butyric, aleric and propionic acids was enhanced. Acid fermentation was affected by the mixing period of each operational cycle. Specific rates of solubilization and VFA production were lower at the mixing period of 0.25 h/cycle. Volatile fatty acids composition was also influenced by the duration of the mixing period in each operational cycle. Reduction of HRT from 12 h to 9 h did not.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT In the last decades, the awareness of environmental issues has increased in society considerably. There is an increasing need to improve the effluent quality of domestic wastewater treatment processes. This thesis describes the application of the Sequencing Batch Reactor (SBR) technology for Biological Nutrient Removal (BNR) from the wastewater. In particular, the work presented evolves from the nitrogen removal to the biological nutrient removal (i.e. nitrogen plus phosphorous removal) with special attention to the operational strategy design, the identification of possible reactor cycle controls or the influent composition related to the process efficiency. In such sense, also the use of ethanol as an external carbon (when low influent Carbon:Phosphorus (C:P) or Carbon:Nitrogen (C:N) ratios are presented) are studied as an alternative to maintain the BNR efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: In order to control the eutrophication problems, the removal of phosphorus has been increasingly important. The biological phosphorus removal using sequencing batch reactor (SBR) was investigated using simulated municipal wastewater. Experiments were carried out in eight sequencing batch reactors (SBRs) at hydraulic retention time (HRT) of 5 d. The experiment is operated at loading rates (LR) of 5.0, 4.5, 4.0, 3.5 and 3.0 mg/L.d. The mixed cultured growth is increased with the increasing of LR according to the suspended solids readings. The graph of the suspended solid concentration, the phosphorus removal and the chemical oxygen demand (COD) removal is almost same which is increasing by time and loading rate. The higher the loading rate, the higher the value of suspended solid, phosphorus removal and COD removal. LR 5 mg/L.d shows the highest suspended solid (SS) concentration with average value of 846.24 mg/L. The highest value of phosphorus removal is at loading rate 5.0 mg/L.d with average removal of 57.38%. The COD removal is also highest at loading rate 5.0 mg/L.d with average removal of 64.33%. The removal was influenced by the biofilm growth according to the suspended solid readings. The highest SS reading give the highest removal for both phosphorus and COD. According to the Design Expert plotted, the highest phosphorus removal can be achieved at LR 5.0 mg/L with 56.89% removal. Same result in Design Expert for COD removal which give the highest removal of 61.69% at LR 5.0 mg/L.d. As for the SS concentration, the Design Expert determine that the optimum value of SS is at LR 5.0 mg/L.d with the value of 840.92 mg/L.

This book was released on 2001 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequencing Batch Reactor (SBR) had been found to be an alternative biological treatment for simltaneous removal of carbon, nitrogen and phosporous from domestic wastewater. Nevertheless studies of this alternative treatment system are few in Malaysis. Thus, research has to be done to explore the potentials of such treatment in our country. A bench scale SBR with a working volume of 2 L, was set up. the reactor had a stable flowrate of 1.4 L/hr maintaining a food to microorganism ratio of around 0.16 and a minimum sludge age of 6-9 days. In this, two major operational strategies were used in achieving the best removal of the three nutrients. In the first operational strategy where different total cycle hours were applied, the 6 hour total cycle hour produced the best removal effiency in terms of total suspended solids (TSS) [97%], biological oxygen (BOD) [85%], chemical oxygen demand (COD)[87%] and total Kjedahl nitrogen (TKN)[>90%]. Nevertheless phophorus removal seemed to be comparable with the other strategy operations, 8hr and 10 hr total cycle. The next operational strategy involved the manipulation of various ration aerobic and anaerobic period. Three main ration, anaerobic: aerobic (fill:react) ratio of 1:2:7, 1:1 and 1:7:1 were taken into comsideration. Longer aerobic period (fill:ratio ratio 1:2:7) produced the best removal efficiency for TSS(95%), COD(89%), BOD(90%) and TKN(>90%). Total strategies removal efficiency averaged about 38%. Hence, longer aerobic period strategy produced better overall nutrients removal efficiency. In operational strategy involving fill:react, the nitrification rates ranged from 1.2 to 2.4 mg.g-1 VSS day-1 which were compatible to previous studies (Palis & Irvine., 1985; Vuoriranta et al., 1993; Russian et al., 1998). The denitrification rates ranged from 1.2 tp 3.7 mg.g-1 VSS day-1 which were also comparable to previous works (Palis & Irvine, 1985; Vuoriranta et.al., 1993; Bortone et.al., 1994; Rustrian et. Al., 1998). The P-release ranged from 0.018 to 0.027 mg P/g VSS/min while P-uptake rates ranged from 0.010 to 0.024 mg P/g VSS/min.
