Granulation Technology Experiments of Novel Mesoporous Composite Water Purification Material

Abstract:

A novel mesoporous composite water purification material was synthesized from natural zeolite to possess certain water purification properties as well as in proper particle size range for optimal fluid flow, particle retention and mass transfer in fixed bed applications. The meerschaum was used as the framework material in the experimental manufacturing procedure, polyethylene alcohol with carboxylic methylic cellulose was used as cohesive reagent, and H2O2 as bubble-forming agent. And the resulted granular product has good abrasion resistance ability with the measured impact breaking time reaching 12 hours. In addition, its decoloring rate is only 4.4% lower and its CODcr removing is only 13.2% lower than those of the original powder product, respectively. As a whole, the granulation potential and significantly expands the zeolite wastewater treatment application range with (only is not necessary) minor reduction of its treatment efficiency.
