Enhancing the Storm Water Treatment Performance of by Isri R. Mangangka, An Liu, Ashantha Goonetilleke, Prasanna

By Isri R. Mangangka, An Liu, Ashantha Goonetilleke, Prasanna Egodawatta

This ebook identifies the main hydrologic and hydraulic components which impact the functionality of stormwater caliber remedy structures comparable to developed wetlands and bioretention basins. Mathematical relationships derived utilizing conceptual versions underpinned via primary hydraulic conception are awarded to foretell remedy functionality. the main highlights of the booklet will comprise the id of the linkages among influential hydrologic and hydraulic elements for built wetlands and bioretention basins to help extra actual prediction of remedy functionality and powerful layout of those kinds of stormwater remedy structures. in addition, this publication will show off an cutting edge process for utilizing conceptual types to research stormwater remedy process performance.

1. Adopting a similar technique, the required hydraulic parameters were also generated by the use of the conceptual model so that the values corresponding to 10 % increment in runoff volume are available. • Step I: The cumulative pollutant load (obtained from a number of monitored pollutant load data for inlet and outlet) versus cumulative inflow runoff volume was plotted as shown in Fig. 1. • Step II: The cumulative pollutant load reduction for each sector of runoff volume was determined by the difference between cumulative pollutant loads at inlet and outlet for each 10 % sector in the plot.

As Davis et al. (2009) have noted, exposure of NH4+ and NO2− to the atmosphere during the dry period can lead to nitrification due to relatively abundant oxygen content, resulting in excess NO3− washout during subsequent events. This implies that nitrification occurs in the bioretention basin during the dry period. The fact that particulate (TSS and phosphorus) and dissolved pollutants (nitrogen) show different removal characteristics in the bioretention basin can be attributed to different treatment mechanisms.

For performing PCA, objects were the 12 rainfall events while the variables were the percentages of the TSS, TP, TN, NH4+, NO3−, NO2− and PO43− EMC reductions and RI, RD, VR and AD. 2 shows the resulting PCA biplots. A detailed discussion of the PCA method is provided in Appendix B. As seen in Fig. 2, the pollutant EMC reduction vectors are divided into two groups. TSS, TP, PO43−, NO2− and NH4+ EMC reduction vectors are projected on the positive PC1 axis along with AD and VR vectors, while NO3− and TN vectors are projected on the negative PC1 axis.
