Removing Water-Soluble Hazardous Material Spills from Waterways with Carbon

摘要

A model for the removal of water-soluble organic materials from water by carbon-filled, buoyant packets and panels is described. Based on this model, equations are derived for the removal of dissolved organic compounds from waterways by buoyant packets that are either (a) cycled through a water column, or (b) suspended in the waterway by natural turbulence, and by panels mechanically suspended in waterways. Computed results are given for phenol spills. The effects of turbulence on the suspension of buoyant packets and of turbulent mixing and longitudinal dispersion of spills in waterways on the removal of water-soluble hazardous materials, are considered. Buoyant packets are found to be ineffective for removing spills from waterways. The rapid dilution of spills also renders panels ineffective unless the spill is massive and the response is rapid.
