Abstract
This paper reports comparative results of two pilot plant technologies applied for
iron and manganese removal from groundwater as part of the drinking water
treatment. The first technology (FOF) consisted of a two step filtration by using
Romanian natural zeolite of two granulations, and ClO2 as an oxidant and
disinfecting agent. ClO2 injection was split between two columns filled with two
different granulation of Romanian zeolite used as filters. The second technology
(OFMU) consisted of ClO2 oxidation, one step filtration by using Romanian
natural zeolite, and microfiltration-ultrafiltration. The first technology achieved
good performance. The residual concentration of iron and manganese decreased
below the allowed maximum concentration (0.2 mg*L-1 for iron and 0.05 mg*
L-1 for manganese). The second technology indicated a good performance only
for iron removal, while the residual concentration of manganese was over the
allowed maximum concentration.
Keywords: groundwater, zeolite, ClO2, microfiltration-ultrafiltration, iron,
manganese.
1 Introduction
Groundwater has been used for household, livestock and irrigation since the
earliest times [1]. The natural chemical quality of groundwater is generally good,
but high concentrations of certain constituents can cause problems [2].
Keywords
groundwater, zeolite, ClO2, microfiltration-ultrafiltration, iron,
manganese.
