Removing
Heavy Metals from Wastewater
Abstract
This
manual provides general guidelines on how to remove
dissolved metals from wastewaters for discharge
to sanitary sewer systems. Each of the various
stages or operations of wastewater treatment is discussed
with their role in the metals removal process.
The
treatment scheme described is general for metals
removal. Some variations exist among different
systems. This manual is intended to provide, in layman's
terms, a better understanding of the precipitation
process as applied to industrial wastewater treatment.
