Abstract:

The results are given of a study which attempted the following: valildate whether polyphosphate can sequester iron under controlled contidions; establish an updated experimental protocol that can be used to test sequestering; test relative sequestering ability of two different polyphosphates; and begin to understand what water quality variables may effect sequestering. Iron sesquestration by polyphosphate was found favorable to no iron treatment. The presence of calcium in the groundwater models inhibited treatment effectiveness. The polyphosphate sequestrant should be added to the groundwater before the addition of chlorine but simultaneous addition was almost as successful. Other findings of the study are also presented and discussed.
