--- Robin > How do you intend to remove a fraction of a percent,
The fractional percent is with no catalyst present (pure water) but the equilibrium level is much higher with a colloidal catalyst. > and concentrate it to HTP? That is done in a cascade. Because of the enormous density difference, only a few simple stages are needed. We hope to get to mid-grade with three stages, maybe two, and to HTP from there in one final stage, which is done immediately prior to injection so that there is almost no stored HTP. Jones
