This research began because of the need to look for technological alternatives to solve the water supply crisis in my hometown, Cali, Colombia, due to turbidity peaks and contamination events. Field research in Colombia was executed to characterize the suspended particulate matter of a highly turbid river Cauca River to have seasonal information on the composition and particle size distribution, and then to have a starting point for the development of the laboratory studies.

riverbank filtration thesis

The RBF technology has not been proven yet in highly turbid waters, in which the excessive transport of suspended sediments threatens sustainable operation. The renewability of the infiltration capacity due to streambed and aquifer clogging and their opposite self-cleansing because of scouring forces was studied.

Thesis defence J.P. Gutiérrez Marín: riverbank filtration

Therefore, geophysical and geotechnical studies have been performed in the surroundings and riverbed samples have been taken and analyzed. A combination of field and laboratory research was conducted during this research, supported by an extensive review of the literature to determine the feasibility of using the RBF for highly turbid sources. RBF is a surface water filtration method for drinking water through the banks and bed of a river, using extraction wells located near the water body in order to ensure direct aquifer recharge.

Riverbank filtration in highly turbid rivers. Technology Transfer Menu openen.

Field research in Colombia was executed to characterize the suspended particulate matter of a highly turbid river Cauca River to have seasonal information on the composition and particle size distribution, and then to have a starting point for the development of the laboratory studies. This research began because of the need to look for technological alternatives to solve the water supply crisis in my hometown, Cali, Colombia, due to turbidity peaks and contamination events.

In the pursuing of technical solutions, the riverbank filtration RBF has been considered as an alternative with a great potential to be applied in Cali, and many other locations in Rjverbank with similar characteristics. Theses will be available within a few weeks after the actual thesis defence. Natural infiltration rate recovery at low shear stresses was possible during simulated riverbank filtration tests with water consisting of a mixture rivetbank different sediments.
