从胶体化学方面看，投加混凝剂后，混凝剂提供的大量正离子将扩散进入胶体扩散层甚至吸附层，r电位降低，为加强颗粒问的范德华力创造了条件。动态连续过滤器以接触絮凝作用为主，以机械筛滤及沉淀作用为辅。通过对 电位的测定证实：连续过滤的原理是以表面能和范德华力为主的接触絮凝作用，改变微絮凝体 电位为附着创造了条件。故连续过滤属于微絮凝深层过滤范畴。虽然在过滤后期有向表面过滤转变的趋势，但这不是主要的。

附着力主要产生于絮体与滤料表面，以及和先附着的絮凝体相接触。因此，滤料或其沉积物与过滤微絮体问的吸附架桥是连续过滤附着的主要原理。目前普通过滤器一般采用下向流过滤方式，因反冲洗后造成滤料粒径自上至下逐渐增大的滤层结构，上层的小粒度滤料起着主要截污作用，而下层的滤料很少参与过滤，因此是不合理的。为了改善水质并充分发挥整个滤层的截污作用，待滤水应该是先粗后细的过滤方式，即所谓的“反粒径过滤”。作为“反粒径过滤”理论的应用，单一滤料的上向流过滤与传统的下向流式过滤相比，具有提高滤料截污量、延长过滤周期的潜力。“连续动态过滤”为单一滤料上向流过滤的具体应用，具有上述优点。
