Industrial stormwater can contain trace metals above regulatory limits. Although standard water treatment processes are available to treat this water, they are generally expensive and require more maintenance than small companies can afford. Lower-cost, lower-maintenance alternatives are needed.

Peat is a natural material and has long been known for its ability to remove metals from water. At least five different mechanisms on the peat surface are involved in metal removal (Brown, et al. 2000). Various studies have evaluated the ability of peat to remove metals, and copper concentrations up to 8.9% have been reported in samples used to treat wastewater (Lapakko and Eger 1988, Premi 1970).

Peat, although relatively inexpensive, tends to be non-uniform and somewhat difficult to handle. Although loose, fibrous peat can have […]
