Performance Factor
A Performance Factor ranks the treatment chemicals,
whereby the optimal chemical is scored as
a 1.0, and less efficient treatment chemicals
are scored in relationship to the best performer,
always receiving a higher factor. Multiplying
the Performance Factor by the treatment chemical
cost provides a weighted cost that incorporates
both performance and economics.

Without performance factors,
utilities might purchase Carbon D at $550/ton,
which appears to be a value, but because of
its poor performance, actually costs much more
($2860/ton) to achieve the
same results as Carbon A at $1000/ton. |
