这项工作的目标是将化学效应纳入描述颗粒介质过滤器中颗粒沉积的基本理论，对理论进行实验测试，并使用这些结果评估有效过滤的要求和工艺的能力。特别是，研究了溶液化学变化对相对较大或非布朗粒子沉积的影响。这种颗粒足够大，通常直径大于2-3微米，因此它们的传输不会受到布朗扩散的显著影响。包括67个参考文献、表格和图表。

The objectives of this work were to include chemical effects in the fundamental theories that describe the deposition of particles in granular media filters, to test the theories experimentally, and to use these results in assessing requirements for effective filtration and the capabilities of the process. In particular, the effects of changes in solution chemistry on the deposition of relatively large or non-Brownian particles are examined. Such particles are large enough, typically with diameters greater than 2-3 um, that their transport is not significantly affected by Brownian diffusion. Includes 67 references, tables, figures.
