Abstract—The simultaneous biological removal of iron, undesirable color and the subsequent staining of laundry and
manganese and ammonia from simulated contaminated plumbing fixtures. Therefore, the presence of manganese and
groundwater was studied by biological aerated filter using dual iron in drinking water should be avoided and a maximum
layer ceramsite as support material in the lab. The system was contaminant level (MCL) for manganese and iron in water for
simultaneously inoculated with iron and manganese oxidizing drinking is mg/L and in china, respectively. The
bacteria, nitrifying bacteria and nitrification bacteria and a series groundwater is therefore unsuitable for use as drinking water
of experiments was performed to investigate simultaneous without appropriate treatment. So it is essential to their
removal performance of the filter. The influence of variation flow removal.
