Detailed calculations of fermentate in design year 2031:

Assumptions: average flow - 90.4 MLD

Average TSS concentration – 292 mg/L Average TSS load = 90 MLD x 388 mg/L = 26397 kg/d TSS load removed in primary clarifiers @70% removal (1995-2005 data showed 76% removal on average) = 0.7 x 26397 = 18478 kg/d Assuming 2% TS in sludge, primary sludge flow = 18478/ (1000 x 1.02 x 0.02) = 906 m3/d VSS/TSS ratio (2006 plant data suggest 0.815) = 0.80 VSS amount removed in primary clarifiers = 0.75 x 18478 kg/d = 14782 kg/d The reported range of VFA production in side-stream prefermenters is presented in Table A8.



Table A8 - Reported VFA Generation in Side-Stream Prefermenters

Range, unit Reference 0.066 – 0.15 VFA-COD/g solids as COD Barnard, J., Shaw, A. et al. 2005 0.10 – 0.20 g VFA/g VSS applied Tchobanoglous, G., Burton, F. et al. 2003 15 – 70 mg VFA/L hour Rössle, W.H. and Pretorius, W.A. 2001

Calculated values of VFA generation: Method 1 According to recent study presented by (Wentzel, M.C., Ekama, G.A. et al. 2006) COD/VSS ratio for primary sludge varies between 1.58 to 1.93. It is assumed for the purpose of this report that 1 g VSS is equivalent to 1.75 g COD. VFA = 14782 kg VSS/d * 1.75 x 0.10 g VFA-COD/g VSS = 2587 kg VFA-COD/d Data compiled and presented by (Rössle, W.H. and Pretorius, W.A. 2001) summarized typical composition of VFA from prefermenters. According to that study on average 1.28 g VFA-COD was equivalent to 1 g VFA. Therefore: VFA = 2587 kg VFA-COD/d / 1.28 g VFA-COD/g VFA = 2021 kg VFA/d Method 2 VFA = 14782 kg VSS/d x 0.15 kg VFA/kg VSS = 2217 kg VFA/d Method 3 The rate of VFA generation is useful for determining the required tank volume. The most important parameter that determines tank volume is HRT. Reported range of HRT for side-stream prefermenters was in the range of 6 to 42 hours, with average between 15 to 18 hours (Rössle, W.H. and Pretorius, W.A. 2001). For the purpose of this report it is assumed that the average HRT of prefermentation process is 18 hours. VFA = 906 m3/d x 50 g/ m3 hour x 18 hours = 815 kg VFA/d Value of VFA calculated by method 3 differs significantly from values obtained through previous calculations. From operational perspective, it would be possible to increase VFA by extending the retention time in the fermenter. Also, it was reported that fermenter underflow contained approximately 1000 mg/L VFA as COD, and increased flow above desludging pipe allowed to elutriate desired VFA (Lindeke, D. and Barnard, J. 2005). Because of that, it was possible to increase VFA generation rate fourfold (from 50 mg/L to 200 mg/L VFA) in fermenter overflow. On the other hand, temperature was found to have a strong impact on the rate of VFA production. Drop in temperature from 20oC to 10oC was found to decrease the rate of VFA generation by approximately 50% (Barnard, J., Shaw, A. et al. 2005). Calculations by method 3 also reveal that proper design of the retention time in the fermenter will be of utmost importance for the successful operation of BNR plant in the cold climate of Winnipeg, MB.



Estimated amount of VFA for the purpose of modeling was the average value from three calculation methods used, that is 1684 kg VFA/d. Additionally, it was assumed the biodegradable fraction of fermenter supernatant is composed in 80% from readily biodegradable fraction of COD, out of which 50% is VFA see Table A6. That calculates to 4210 kg of COD/day in the fermenter supernatant or 4647 mg COD/L.
