Influence of physical and chemical properties of suspended solids in urban water qualityWangegedara C Gunawardana Masters by Research 2008 - 2011 
Faculty Faculty of Built Environment and Engineering Supervisor/s Prof Sobana Goonetilleke, Dr Leslie Dawes Thesis Abstract Urban stormwater washes pollutants from urban surfaces which are accumulated from various urban activities and is a significant source of pollutants to receiving water.
To protect natural water resources from stormwater pollution, requires mitigation actions such as pollutant traps, detention and retention basins, town planning controls and pollution prevention procedures. The effectiveness of the management plans can be limited due to the complex urban pollutant transportation phenomena. Most of the chemical pollutants in urban stormwater are transported attached to suspended solids so stormwater treatment facilities are designed to remove these solids. However, treatment processes are primarily targeted for treating the first flush and remove the coarser particle sizes only; treatment processes are often inefficient in removing finer particles which can absorb a comparatively higher load of other pollutants. The difficulty in developing treatment processes so that they deal with finer particles is primarily due to the lack of knowledge relating pollutant adsorption to suspended solids and the role of influential parameters. Therefore this research focuses on filling this information gap. |
