建立了一种预测粉末活性炭（PAC）作为中空纤维超滤（UF）预处理剂去除有机物的模型技术。大型和小型PAC-UF中试装置的模型预测得到了成功验证。使用不同的水源、PAC剂量和反洗频率进行试验。以总有机碳为代表的水源中的天然有机物是研究的目标化合物。该建模过程可用于PAC-UF系统的设计和评估。包括17个参考文献、表格、图表。

A modeling technique was developed to predict organics removal by powdered activated carbon (PAC) added as a pretreatment to hollow-fiber ultrafiltration (UF). Model predictions were successfully verified for large- and small-scale PAC-UF pilot plants. Experiments were conducted using different water sources, PAC dosages, and backwashing frequencies. Natural organic matter in the water sources, represented by total organic carbon, was the target compound studied. The modeling procedure can be used in the design and evaluation of PAC-UF systems.
