Assessment of Fe(II), Fe(III) and NaMnO4 dosing for As removal <1 µg/L during aeration-filtration at WTP Prinsenbosch

In 2013, Brabant Water (BW) adopted a new goal of &lt;1 μg/l for As level in the drinking water, resulting in the need to enhance As removal at seven water treatment plants (WPT’s), including WTP Prinsenbosch (As = 2.6 μg/l). Earlier experiences of BW at WTP Dorst had shown that dosing of NaMnO4 to an aeration-filtration system efficiently...
