In filtration of seawater, adsorption of substances dispersed at sizes smaller than the filter pore dimension can result in major error. This error may be particularly severe for pore sizes approaching the 0.45‐ µ m delineation between dissolved and particulate. A model based on diffusion in forced convection and interception predicts that, under typical conditions for filtration of seawater, a large portion of materials dispersed at sizes smaller than the filter pore dimension will interact with the filter pore wall. However, the fraction of these interacting materials that adsorb must be a function of many variables, both physical and surface chemical.
