Runoff Pollution Treatment Using An Up-Flow Equipment With Limestone And Geotextil filtration media

Abstract

Runoff drags pollutant from different urban surfaces causing diffuse pollution in natural or artificial water bodies. To solve this problem, several solutions have been developed to purify the run-off water before the final spill, but still it is necessary to improve the applicability and efficiency of these systems. The project that is presented in this paper is focused on developing a System for Catchment, Pre-treatment and Treatment (SCPT) of contaminated runoff coming from impervious surfaces. The concept of SCPT is an on-line, up-flow filtration system, with the main elements of pervious pavements, which are being geotextiles and open grade gravel. The objectives of this research are to determine the influence of the main factors that affect SCPT efficiency and to evaluate the effects of SCPT long term use in its operational behavior.
