RIVERBANK FILTRATION THESIS

  • June 30, 2019

Natural infiltration rate recovery at low shear stresses was possible during simulated riverbank filtration tests with water consisting of a mixture of different sediments. 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. Clogging of both the riverbed and deeper aquifer may increase flow resistance, reducing water revenues over the course of time. Technology Transfer Menu openen. About TU Delft Menu openen. The resulting information of this research has been applied for the development of the design of a large-scale horizontal collector well, which will be constructed in the city of Cali. The RBF technology has not been proven yet in highly turbid waters, in which the excessive transport of suspended sediments threatens sustainable operation.

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. The RBF technology has not been proven yet in highly turbid waters, in which the excessive transport of suspended sediments threatens sustainable operation.

riverbank filtration thesis

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. The renewability of the infiltration capacity due to streambed and aquifer clogging and their opposite self-cleansing because of scouring forces was studied.

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 Colombia with similar characteristics.

Thesis defence J.P. Gutiérrez Marín: riverbank filtration

About TU Delft Menu openen. This has been done with an emphasis on potential clogging effects of the suspended sediments carried by the highly turbid Cauca River on the riverbed.

Riverbank filtration in highly turbid rivers. 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.

Therefore, geophysical and geotechnical studies have been performed in the surroundings and riverbed samples have been taken and analyzed. Theses will be available within a few weeks after the actual thesis defence. Clogging of both the riverbed and deeper aquifer may increase flow resistance, reducing water revenues over the course of time. Natural infiltration rate recovery at low shear stresses was possible during simulated riverbank filtration tests with fiiltration consisting of a mixture of different sediments.
