In sewer networks without considerable amounts of sediments, the anaerobic processes are dominated by the acidogenic production of VFA and C02 and by sulfate reduction (hydrogen sulfide production). The methanogenic phase can normally be excluded as being of minor importance. These facts were verified by Tanaka and Hvitved-Jacobsen (1999) and Tanaka (1998) under sewer conditions in a number of laboratory experiments and in the field.

The simulations depicted in Figure 8.8 also show that arather low hydrogen sulfide concentration is predicted in the gravity sewer. Only minor problems related to hydrogen sulfide production may therefore arise. Until now, the WATS model did not include sulfide release to the sewer atmosphere, sulfide oxidation or sulfide precipitation that may further reduce the concentrations shown. The predicted sulfide concentrations are, therefore, maximum levels. In case a natural capacity of iron salts in the wastewater to precipitate sulfide is inadequate, the sulfide concentrations are considered at a level that can be relatively easily controlled.

Putrefaction contributions to total hydrogen sulfide production averaged 23% with a range of 5-57% for the two small lakes investigated. It is estimated that over a six month primary...

IV. Table II summarizes sulfate reduction rate data at both Third Sister and Frains Lakes and indicates a range of 0.7 to 3.2 mg S L 1 d 1 and a mean of 1.7 at both stations for 23 determinations. Table III includes data from putrefactive hydrogen sulfide production at the two lakes showing that rates varied from 0.13 at Frains Lake to 1.51 mg S L1 d 1 at Third Sister with a mean of approximately 0.4 mg S L 1 d 1. Hydrogen sulfide contributions from putrefaction, summarized in Table IV, were found to range from 5.1 to 53.0 percent with means of 27.6, 18.3 and 11.1 percent for Thira Sister West, East and Frains sites respectively. Although the sulfate reduction values are similar to those obtained by others (0.01-15 mg S L 1 d-1 14), there are no other putrefactive data with which to compare the values of Table III. Microbial enumeration data averaged 5 x 102 and 2 x 104 cells mL 1 for sulfate reducers and proteolytic bacteria respectively. These values are similar to those obtained by others (14). 

Variations Between Lakes. Results of a study to evaluate sulfide production variation with water depth is given in Table V. In this experiment, samples were taken from five different sediment depths over a two-day period at each lake in early October. At both lakes sulfate reduction exceeded putrefaction by a factor of approximately 2 with overall mean rates of 0.55 and 0.29 mg S L-kH1 respectively. Sulfate reduction exceeded cysteine decomposition in all samples except one collected from Third Sister Lake at 17 m. Results of this study snow a good correlation at Third Sister Lake between percent hydrogen sulfide production attributable to putrefaction and depth of sampling station (r=0.94) and oxidation-reduction potential (r=0.98). This correlation was not observed at Frains Lake. A possible factor m differences observed may be the physical nature of the sediment at Frains which was less dense and more flocculent than thatofTliird Sister. 

Variation with Sediment Depth. This investigation was undertaken to determine the variation of hydrogen sulfide production and associated microorganisms within the upper 8 cm of sediment from East station. Five fractions were examined representing depths of 0-1,1-2, 3-4, 5-6 and 8-9 cm. Results are summarized in Table VI. Maximum values for both sulfate... 

Although hydrogen sulfide production via putrefaction correlated strongly with numbers of proteolytic bacteria (r=0.94,0.86), none was found for protein (r=0.16) or organic carbon (r=034) in Third Sister Lake. The significance of this is not known due to the many associated uncertainties, but it seems reasonable to assume that protein input would result in enhanced hydrogen sulfide production via putrefaction. Results of experiments to test this in laboratory bioreactor studies indicated that protein (egg albumin) added at the rate of approximately 20 ppm d 1 increased the population of putrefying bacteria by 90 percent and the rate of sulfide production via putrefaction by...
