Abstract |
A mathematical-chemical relationship derived to predict the most effective concentrations of Ca(2+) for coagulation of mangnaese oxide particles and deposition on a rotating disc type silica surface, was shown to predict the effective concentration of Ca(2+) for removal of manganese oxide by model rapid sand filters. The relationship derived was acceptable in predicting the removal efficiency of both 1-inch ID - 4-inch deep and 4-inch ID - 3-foot deep sand filters. The cost of treating naturally occurring waters of Wyoming was shown to be small if rapid sand filtration plants were available. |
