Abstract
An experimental apparatus, referred to herein as a Dual Culture Diffusion Apparatus (DCDA), has been developed and operated to permit the extraction of process kinetic data for several types of particle-water interactions. The DCDA is constructed of two culture vessels separated only by a thin membrane filter, thus facilitating the separation of two particulate suspensions while at the same time permitting their interaction by diffusion of dissolved substances through the membrane. This manuscript describes how the apparatus has been calibrated and applied to measure the rate at which available phosphorus is released from various types of particulates suspended in lake water media.
