CONTAMINANTS TREATED
Metals
Nickel, Copper, Zinc, Arsenic, Manganese, Iron, Aluminum, Lead, Cadmium
Nitrogen-Based
Unionized Ammonia (NH3), Nitrate (NO3), Cyanide (CN-)
Other
Total Suspended Solids (TSS), Sulfate (SO4), Phosphate (PO4), Sulfurous compounds (ex. Thiosalts as hydrogen sulfide precursors), Biological Oxygen Demand (BOD5), etc.
Viruses and pathogens
Disinfection of Drinking Water
Typical Treatment Steps
pH Adjustment
Ex. for metals removal (quicklime, hydrated lime, NaOH, soda ash, etc.)
Settling
Ex. clarifier, pond
Coagulation & Flocculation
Ex. ferric sulfate, alum, polymer
High Density Sludge
Ex. to respect very low contaminant levels required by permits
Special Considerations
