- Summary:
- Chemical treatment systems (CTS) are implemented in areas where traditional, physical erosion and sediment control practices will not meet water quality goals for construction site runoff. The purpose of CTS is to reduce the amount of suspended sediment which would be released using conventional erosion control systems. The primary mechanism is the introduction of chemical flocculants into runoff, resulting in a binding of the suspended clays and silts together into larger particles which settle more quickly or can be filtered from the stormwater. Flow control through CTS is of vital importance for the proper dosing of stormwater runoff. All normal hydrologic analyses must be done to insure that reasonable peak flows are accounted for along with typical flows from designed storm events. Once analysis is adequately addressed, then the project can deal with the complexities of design and dose rate requirements. The overall objectives of this book are twofold. First, it is designed to provide a technically credible basis for best management practices for the use of CTS for turbidity reduction on road construction projects. Secondly, it is designed to identify the most important variables to address when selecting chemical treatment best management practices for a particular site.
