Abstract:
Passive
methods of treating mine water use chemical and biological processes
that
decrease metal concentrations and neutralize acidity. Compared with
conventional
chemical treatment, passive methods generally require more land
area,
but use less costly reagents and require less operational attention and
maintenance. Currently, three types of passive
technologies exist: aerobic
wetlands,
organic substrate wetlands, and anoxic limestone drains. Aerobic
wetlands
promote mixed oxidation and hydrolysis reactions, and are most
effective
when the raw mine water is net alkaline.
Organic substrate wetlands
promote
anaerobic bacterial activity that results in the precipitation of metal
sulfides
and the generation of bicarbonate alkalinity.
Anoxic limestone drains
generate
bicarbonate alkalinity and can be useful for the pretreatment of mine
water
before it flows into wetland.
Rates
of metal and acidity removal for passive systems have been developed
emperically
by the U.S. Bureau of Mines. Aerobic
wetlands remove Fe and Mn from
alkaline
water at rates of 10-20 and 0.5-1.0g.m-2.d-1, respectively. Wetlands
with a
composted organic substrate remove acidity from mine water at rates of
3-9gm-2.d-1. A model for the design and sizing of passive
treatment systems is
presented
in this report.
