Dyna-Aqua™ Lead provides benefits superior to either chemical precipitation or ion exchange, commercial techniques which are costly due to the high cost of required chemicals.
- How Lead Comes Into Industrial Wastewater?
Water characteristics promoting the corrosion of water include low pH, low total dissolved solids, high water temperature and high concentrations of dissolved gasses such as oxygen or carbon dioxide. Lead levels are monitored by the Environmental Protection Agency and cumulative exposure can lead to irreversible damage to the gastrointestinal, hematologic and nervous systems and may cause death.
Lead transported through the water system comes from:
- Lead piping
- Lead solder
- Stabilizers used in the extrusion of PVC piping
- Brass fittings which are composed of copper, zinc and lead corroding when chloramines are used to disinfect water, leading to the production of ammonia

- Adsorption Results
Adsorption results show pH dependency with a Freundlich isotherm fit. Activated alumina possesses both Lewis and Bronsted acidic and basic sites. While being amphoteric alumina works best for lead removal when the pH of the aqueous stream is in the pH range of 5.5 to 6.0.
