Impact of the Physicochemical Environment Upon Certain Floc Properties

这项研究将在实验上将絮体密度和渗透率与絮体大小以及地层中普遍存在的水动力和物理化学条件联系起来。絮凝强度将通过测量破坏支撑在筛网上的絮凝体所需的流体速度来确定，水被强制通过筛网。将测定单个絮体轮廓的分维，以提供有关絮体生长机理的一些信息。絮凝体的大小、密度、渗透性和强度在矿物分离、水处理、陶瓷加工和环境工程等领域都很重要。重要的是开发测量这些絮体特性的技术，并将它们与絮体形成过程中普遍存在的水动力和物理化学条件联系起来。

This research will relate experimentally floc density and permeability to floc size and to the hydrodynamic and physicochemical conditions prevailing during formation. Floc strength will be determined on a relative basis by measuring the fluid velocity necessary to disrupt a floc supported on a screen through which water is forced. Fractal dimensions of the contours of individual flocs will be determined to give some information on the mechanisms of floc growth. Floc size, density, permeability, and strength are important in such areas as minerals separation, water treatment, ceramics processing, and environmental engineering. It is important to develop techniques for measuring these floc characteristics and to relate them to the hydrodynamic and physicochemical conditions prevailing during floc formation.
