Ceramic Membrane Filtration from Industrial Ashes

Abstract

This research studied the efficiencies of ceramic membrane filtration from industrial asphalt for dyeing wastewater treatment by forming a ceramic membrane in a diameter of 6 cm, height of 2 cm. An appropriate proportion of industrial ashes: kaolin: sodium hydroxide solution mixed with sodium silicate solution was 46:18:36 at 800 ° C. For the properties analysis of ceramic membrane made from industrial ashes found that a shrinkage value, compression resistance, and density, water absorption value, and permeate flux were found 3 percents, 0.6 Kilonewtons per cubic centimeter, and 1.93 grams per cubic centimeter, 45 percents, 8.61 milliliters per square centimeter per minute, respectively. Structural surface by a scanning electron microscopy was found that the porous inside of material was closely aligned together. Moreover, precipitation of synthetic wastewater by using industrial ashes could help to increase the efficiencies of dyeing wastewater treatment. From the experiment, it was found that the precipitation of synthetic wastewater with industrial ash was 94 percent filtration efficiency. On the other hand, the efficiencies of synthetic wastewater treatment without precipitating of industrial ashes found only 69 percent. Moreover, this research offers a new option for industrial wastes utilization.
