Abstract
The results from a new pilot scale plant of the MicroDrop Aqua arsenic removal technology are introduced. The technology is based on the employing of electrochemical iron dissolution and efficient aeration prior to sand filtration. The pilot treatment was used to study effectiveness of iron release in an electro-dissolution process that is taking place in an iron generator. It was found that there is a need of some extra time to reach a state of steady iron release and that could not be achieved within a short period of 10-20 minutes. The pilot plant proved to be able to remove arsenic to value below 5μg/L and it has been shown that the process efficiency depends on the applied current. Moreover, it was found that iron accumulation in the sand filter had a positive effect on the arsenic removal activity and it shall be considered in future tests. The presented method enables efficiently, without chemical addition and easily to remove arsenic from contaminated groundwater.
