Odor Control >> Why Do I Have A Sewage Smell In My House

Results of odor and odorants measurement at Districts A, B, C, D and E.In the instrumental analysis for individual sulfur odorants, H2S and CH3SH concentrations were higher than DMS or DMDS both before and after the agent treatment. The average NH3 concentrations before and after the treatment of the Agent-A were 0.6 ppm, Why Do I Have A Sewage Smell In My House respectively. 

Considering the published odor threshold for NH3(i.e., 4.1 to 37 ppm, [21]), contribution of NH3 to odor sensation might not be significant at the site.Since a masking agent like Agent-A does not degrade nor transform odorants from sewer systems, but it literally covers the sewer odor with its strong and relatively pleasant odor [22,23], Why Do I Have A Sewage Smell In My House it was not expected that degradation of odorants would happen. 

From the fact that the odor dilution values measured before and after the treatment were not much different and Why Do I Have A Sewage Smell In My House the odor characters were also similar, it was assumed that the masking agent failed to cover the sewer odor enough.The results from the analysis of wastewater collected from the site before and after the treatment of the Agent-A showed little difference in water qualities, except BOD (Table 3). 

However, we do not think that the BOD increase was due to the added odor-reducing agent, since the amount of the agent applied to the site should be much smaller than that of wastewater generated in the districtWastewater characteristics before and Why Do I Have A Sewage Smell In My House after treatment with odor-reducing agents at 5 districts.3.2.

Effectiveness of Agent-B in Control of Odors from Sewer Figure 4(B)shows the TRS profiles obtained at the District-TWO before (B1) and after (B2) the application of the Agent-B. In this area, Why Do I Have A Sewage Smell In My House not much odor-causing gas was released. The TRS concentration was always within 0 to 500 ppb with a relatively high concentration during the day.

Regarding the effectiveness of the Agent-B, Why Do I Have A Sewage Smell In My House the agent did not result in any difference in the time profiles of TRS concentration observed before and after the treatment (Figure 4(B)). The daily average TRS values were not different, either (p= 0.34); the daily average was 100 ppb before the agent was applied, while it was 140 ppb after the agent with applied.

The instrumental analysis performed with the gas samples collected at the District-TWO showed a similar result to that of the samples collected from District-ONE. The odor dilution and Why Do I Have A Sewage Smell In My House the concentrations of individual sulfur compounds of gas samples collected before and after the Agent-B treatment were not much different except for CH3SH (Table 2). 

The result of the analysis with the wastewater samples collected before and after the agent treatment did not show much difference (Table 3).In the case of District-TWO, in fact, the sprayed amount of the solution (i.e., Agent-B which is alkaline solution) was relatively large, Why Do I Have A Sewage Smell In My House compared to other agents applied in this study. 

However, it could not effectively prevent the release of H2S from the sewage; as shown in Figure 4(B), the profiles of TRS concentration measured before and Why Do I Have A Sewage Smell In My House after the agent were almost identical. In addition, the sewage pH did not change much. From these findings, it was assumed that the dose of Agent-B applied in District-TWO was not enough to result in any changes of sewage characteristics. 

Therefore, it was concluded that the application of the odor-reducing agent (i.e., Agent-B) were not effective.Effectiveness of Agent-C in Control of Odor from Sewer Figure 4(C)shows the time profiles of TRS concentration monitored at the District-THREE before (C1) and Why Do I Have A Sewage Smell In My House after (C2) application of the Agent-C. 

The site was characterized by the large difference in TRS emissions between day and night. From Why Do I Have A Sewage Smell In My House Figure 4(C)the TRS observed at night was far lower than those observed during the daytime. It was because the floating population of the weekdays was 3 to 4 times higher than that of weekend. After Agent-C was applied, the weekly average concentration of TRS was relatively lower than those of Districts-ONE and -TWO.

Peaks in the TRS profiles could be observed after noon, Why Do I Have A Sewage Smell In My House while the detected TRS level was low from midnight till the noon (Figure 4(C)). As the cases of the Agents-A and -B, the time profiles of TRS emission observed before and after the odor-reducing agent was applied did not show statistically much difference.

Even though the average of TRS emissions recorded after the Agent-C treatment was lower than that recorded before the treatment; the daily average TRS concentrations measured before and Why Do I Have A Sewage Smell In My House after the treatment were 65 ppb and 40 ppb, respectively.

The odor dilution and Why Do I Have A Sewage Smell In My House the concentration of individual odorants of the samples collected at the manhole where the on-line TRS analyzer was installed in District-THREE showed similar results to those obtained from Districts-ONE and -TWO (Table 2); the odor quality of the gas samples was not improved by the application of the odor-reducing agent (i.e., Agent-C). 

In fact, odor dilution after the agent treatment was higher than those observed before the treatment (p< 0.05). The discrepancy between the odor dilution and the average TRS values was attributed to the possibility that more Why Do I Have A Sewage Smell In My House odorous gases were collected when the grab-sampling event happened after the agent treatment. 

Other individual odorants and Why Do I Have A Sewage Smell In My House H2S were also detected at higher levels after the agent had been applied.The result from the analysis of wastewater samples collected at the District-THREE revealed the Agent-C did not have any effect on the water quality of the sewage in the sewer, either. Although higher BOD and SS levels could be observed after the agent treatment, we do not believe it was because of the addition of the agent. 

Effectiveness of Agent-D in Control of Odors from SewerFigure 4(D)shows the time profiles of TRS concentration observed in District-FOUR, before (D1) and after (D2) Agent-D was applied. Since the area is occupied with a number of small-to-medium size shops and jewelers, Why Do I Have A Sewage Smell In My House the floating population increases at lunch and dinner times on weekdays, particularly from 12 to19 o'clock. The changes of the floating population affected the amount of wastewater produced in the district.
