What is DEAL®?
DEAL® is a patented process product where by DE (diatomaceous earth) is coated with aluminum oxide-hydroxide (AlOOH).
DEAL® is highly electropositive (up to +80 mV), while bare DE is highly electronegative (-70mV).
The strong electropositive forces attract and retain colloidal particles that are intrinsically electronegative in water.
How Does Standard DE Work?
DEAL® is a functionalized/improved form of DE. DE has been used extensively to purify water in swimming pools, as well as
industrial and municipal plants.
A precoat filter bed of DE, generally 3 mm thick, is first formed and then additional DE is added to the body fluid.
When the pressure drop exceeds specification, the DE bed, with contaminants, is internally back washed and discarded.
DE has limited efficiency for removing bacteria, virus and colloids, and no capability for removing arsenic or lead.
More About DEAL®
DEAL® is currently available with an average particle size of 60 microns.
When used in the precoat process, this grade of DEAL® can remove 99.99999% of bacteria and virus, and reduce soluble
lead from 150 ppb down to 7 ppb.
