I don't necessarily buy that the "2 step" process has the positive impact on the environment that is purported. For neutralization to occur between strong acids/alkalines, there needs to be a molar equivelence. My thought is that variability introduced via different chemicals, uptake rates, length of time applied (amount) applied, etc. would negate the advertised benefits. Unless the chemicals are highly buffered, there would seem to be little benefit, except that we can tell customers that we through on a neutralizing material. For the reasons above, I won't state to a customer.
