Abstract
Disclosed are nano-engineered porous ceramic composite filtration media for removal of phosphorous contaminates from wastewater and other water or liquid sources. Such porous ceramic media has high surface area and an interconnecting hierarchical pore structure containing nano-iron oxide/oxyhydroxide compounds, as well as other nano materials, surfactants, ligands or other compounds appropriate for removing higher amounts of phosphorous or phosphorous compounds. The composite media can be modified with nano-phased materials grown on the high surface area and addition of other compounds, contains hierarchical, interconnected porosity ranging from nanometer to millimeter in size that provides high permeability substrate especially suited for removal of contaminants at the interface of the water or other fluids and the nanomaterial or surfactants residing on the surfaces of the porous structure.
