Full Description

This powerpoint presentation begins by providing a brief overview of riverbank filtration (RBF), and presents the framework for assessing the feasibility ofRBF that includes the following four step methodology developed at UNESCO-IHE:hydraulic simulation using MODFLOW;determination of share of bank filtrate and localgroundwater using NASRI Bank Filtration Simulator;prediction of the water quality usingalgorithms/guidelines, developed based onliterature review; and,comparison of the capital and Oa four-step methodology was developed for assessingfeasibility of RBF for water treatment;spacing between the wells and distance of the wellsfrom the bank can be varied to get the required waterquality and quantity from the wells for givenallowable drawdown; a guideline for estimation of water quality of RBFsystem for given travel time and travel distance wasdeveloped based on literature review; and,RBF is feasible in selected cities of Malawi, fromHydraulic, Water Quality as well as Cost considerations. Includes tables, figures.
