@StephanF
Aluminum has historically been used in water filtration systems to coagulate impurities by raising and neutralizing the Zeta Potential.
From the Zeta-Meter manual aimed at water filtration system managers under Coagulant Aids:
“Coagulant aids are excellent tools for dealing with seasonal problem periods
when alum alone is ineffective. They can also be used to increase plant capacity
without increasing physical plant size.
Activated silica was used for this purpose before organic polymers became popular.
Activated silica produces large, dense, fast settling alum flocs and simultaneously
toughens it to allow higher rates of filtration or longer filter runs.”
So Silica is recommended for use with Aluminum to increase the coagulation effect of Aluminum.
This calls into question the use of Silica in drinking water, since it might potentiate the Aluminum that is already in the body and thereby increase the coagulation effect on blood cells.
Thank you StephanF for all the hard work that you have done in sharing your knowledge of ZETA Potential.
