This powerpoint presentation begins by providing a brief overview of regulatory drivers and limits for boron. Boron speciation in water is presented, along with second pass alkalization, and feed alkalization. Presentation conclusions indicate the following:
First Pass Feed Alkalization
at ambient pH (8.0), only manufacturer A met permeate boron
goal of 0.5 mg/L;
feedwater alkalinization to pH 9.0 was required for all suppliers
to comply boron goal; and,
projection models generally conservative estimates.
Second Pass Feed Alkalization:
pH 10 achieves significant reduction at low NaOH dose;
reduces 2nd pass size by >35%; and,
projection models generally conservative estimates. Includes tables, figures.
