Adsorption of Microorganisms to Sand Diatomaceous Earth Particles Coated With Metallic Hydroxides

Abstract

Particles of diatomaceous earth and sand were coated with metallic hydroxides. The coating increased the concentration of metals associated with the particles, their zeta potential, and their ability to adsorb microorganisms in water. The maximum adsorption of microorganisms was achieved using particles coated with a combination of ferric hydroxide and aluminum hydroxide.
