本powerpoint演示文稿首先简要概述了硼的监管驱动因素和限制。介绍了水中硼的形态，以及二次碱化和进料碱化。陈述结论如下: 首程饲料碱化 在环境pH值（8.0）下，只有制造商A会渗透硼 目标为0.5 mg/L； 所有供应商都需要将给水碱化至pH 9.0 遵守目标；和 投影模型通常是保守估计。 二次进料碱化: pH 10在低NaOH剂量下显著降低； 将第二道工序尺寸减少35%以上； 和 投影模型通常是保守估计。包括表格、数字。

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.
