Therefore, BF could be a pre-treatment for the DF treatment system, and the existing facility could be adapted for iron and manganese removal.ĪPHA, AWWA, WPCF (2005) Standard methods for the examination of water and wastewater, 21st edn. BF performed slightly better in THM precursor removal (52%) than DF (42%). This was the principal drawback of BF comparing with the already existing direct filtration (DF) treatment plant. The same happened in the wells system, showing the dissolution of iron, manganese and sulphide in the bank filtrate. A change to reduced redox conditions was observed in the large column experiment. The first fraction was removed during the first days of travel time of the bank filtrate. In both cases, an easily degradable organic matter fraction was modelled in the large column a moderate degradable fraction was identified as well. The NOM and THM precursor removal in the large column and the test filter were effectively modelled. Both systems demonstrated a good removal of NOM and trihalomethanes (THM) precursors with a preference removal of THM precursors. The well systems and the column showed the removal of turbidity and colour from around 7 NTU and 65 Pt–Co, respectively, to below the local regulations (1 NTU and 15 Pt–Co units). Studies in two periods at two bank filtrations well systems, in a 45-m-length column and in a test filter laboratory scale set-up, were performed. General water quality parameters, natural organic matter (NOM) and redox conditions were evaluated in Lagoa do Peri, a costal lake in Santa Catarina, South Brazil.
