Water
characteristics promoting the corrosion of water
include low pH, low total dissolved solids, high
water temperature and high concentrations of
dissolved gases 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.
Dyna-AquaTM
Lead is a large particle activated alumina with an
effective size of greater than 200 microns. It is
specifically designed, modified and chemically
treated in order to enhance the removal of dissolved
lead from a water stream. It is ideal for point of
use applications and more cost efficient and less
energy intensive than reverse osmosis, the only
other commercially available point of use
technology. Dyna-AquaTM
offers a cost efficient, simple and reliable
solution for municipal, industrial and home use
needs.
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
Dyna-AquaTM
Lead provides benefits superior to either chemical
precipitation or ion exchange, commercial techniques
which are costly due to the high cost of required
chemicals.
Adsorption results
show a 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.
