Abstract

Runoff can cause urban flooding as well as carry a high load of pollutants. The permeable concrete pavement can retain pollutants present in the runoff and reduce its volume. Thus, the percolation effect of runoff on permeable concrete pavements executed with three different dosing methods, American Concrete Institute (ACI) (2010), Zheng, Chen and Wang (2012) and Nguyen et al. (2014) was evaluated. The aim was to analyze the pollutant retention in permeable pavements and take into account different flow rates. Three pavements were built on a laboratory scale, one for each dosing method. Regarding the evaluation of the percolation effect, the following parameters were analyzed in the runoff and after the percolation: apparent color, turbidity, pH, copper, zinc, and total coliforms. ACI and Nguyen et al. provided an average reduction of more than 65% for turbidity and more than 50% for apparent color. The total coliforms removal was over 95% for the three dosing methods. The zinc concentration reduction was similar for the three dosing methods, and copper concentration was higher in the Nguyen et al. method, on average 83.8%.

Author Biographies

Nayara Becker, Fundação Universidade Regional de Blumenau

Graduated in Chemical Engineering from Fundação Universidade Regional de Blumenau (2015). Master's Degree in Environmental Engineering from the Universidade Regional de Blumenau Foundation (2018), in which the quality of surface runoff water from its percolation on the permeable concrete pavement was evaluated. In laboratory experiments, the interference of three permeable concrete dosage methods on the quality of runoff was analyzed: American Concrete Institute (2010), Nguyen et al. (2014), and Zheng, Chen, and Wang (2012). Currently studying for a Doctorate in Environmental Engineering at the Post-Graduate Program in Environmental Engineering at Fundação Universidade Regional de Blumenau. In the doctorate, the project´s continuations in the master's program are being carried out, with the application in loco of the dosage method that obtained a better response. The proposal is to apply the permeable concrete pavement in the university parking lot and evaluate the interference of the permeable concrete pavement in the water quality of the surface runoff in a situation with the occurrence of climatic and traffic adversities.
