Data underlying the publication: Meta-omics profiling of full-scale groundwater rapid sand filters explains stratification of iron, ammonium and manganese removals.

We hypothesized that genetically homogeneous RSFs’ microbial communities hold the ability to rapidly modify their pool of expressed proteins to metabolically respond to the environmental conditions encountered at a given filter height. To this end, we quantified the in situ removal of iron, manganese, and ammonium, and resolved the taxonomy and function of the microbial communities along the filter height of two full-scale RSF plants, one dual-media (anthracite and sand) single filter system and one comprising two single-media sand filters in series.The data here presented comprises the mineral content of the coating as well as the metaproteomics and metagenomics of the microbial communities.<br>
