This study investigates five different fouling models and contributing factors in membrane-filtration blocking mechanisms in a constant-pressure mode. A polyvinylidene fluoride membrane was used to study the fouling effects of a complex mixture of foulants (a latex-bed suspension, soybean oil, and inorganics) on pristine and chemically cleaned membranes in the presence of humic acid. A significance ratio in linear regression results (p-value) was used to assess the contribution of fouling mechanism in each model. The results indicate that Hermia and Bowen’s models correspond closely with the experiment results and confirms that complete blocking is dominant fouling model. We also verify that each developed model is dependent on its experimental conditions. Moreover, the role of complex mixtures, including inorganic foulants, in the fouling process needs to be modified as modified for ceramic membranes and natural organic matter removal in the Wiesner and Kilduff models, respectively.

这项研究调查了五种不同的污垢模型以及在恒压模式下膜过滤阻滞机理的影响因素。聚偏二氟乙烯膜用于研究腐殖酸存在下污垢（乳胶床悬浮液，大豆油和无机物）的复杂混合物对原始膜和化学清洁膜的结垢作用。线性回归结果的显着性比率（p值）用于评估每个模型中结垢机制的贡献。结果表明，Hermia和Bowen的模型与实验结果密切相关，并证实了完全阻塞是主要的结垢模型。我们还验证了每个开发的模型都取决于其实验条件。此外，复杂混合物的作用，包括无机污垢，
