Paper Title:
Study on Removal of Organic Matter by Enhanced Filtration with Iron-Coated Ceramsite
  Abstract

Coating of iron-oxide can improve the surface characters of original filter media, and will enhance filtration efficiency, this study assume the high-temperature method to prepare iron-coated ceramsite. Four coating parameters were investigated: pH value, FeCl3 concentration, baking temperature and baking time. The scanning electron microscope (SEM) and X-Ray diffraction were used to observe the surface properties of the coated layer. Using iron-coated ceramsite in enhanced filtration, removal properties of organic matter were studied. The experimental result indicated under the modifying condition of 0.4 pH value, 2mol/L FeCl3, 650°C baking temperature and 3h baking time, the iron-coated ceramsite has the best removal of organic matter. It has bigger specific surface area. The removal efficiency was increased with the increment of the influent concentration of organic matter and the decrease of velocity. When the pH value was slightly acid, the effect on organic matter removing was best.
