ZEOLITE AS A ZINC REMOVAL MEDIA.
Throughout my work tat there have been a larger variety of contaminants that have proven to be difficult to remove through design. One of these is the Zinc ion that can be present in due to a large variety of reasons. The levels of Zinc in stormwater runoff has been regulated and benchmarks have been set for the zinc levels allowed. Zinc can be produced from a wide range of areas including galvanized roofs and surfaces, motor oils, wear debris from tires, atmospheric deposition and fertilizers. There are a wide range of processes that are designed to remove Zinc from stormwater. The following document explains the removal of Zinc in great detail.
Three of our tertiary treatment systems use Zeolite as its main removal media, alongside varying percents of Activaed carbon, AFM and Perlite among others. These tertiary systems that should be used if Zinc removal is required are the, and
