Description
We have developed high performance and multi functional inorganic materials for wastewater treatment. We have discovered that a Mg-Al-C1 form hydrotalcite 'TPEX' has high selectivity and large adsorbing capacity for phosphate anions. We have examined granulation of TPEX for a flow method with polystyrene-acrylate, polyacrylate, epoxy resin, polyacrylamido as a binder. From the results, it was cleared that the granular adsorbent granulated with polyacrylamido and epoxy resin as a binder showed high values in adsorbing capacity and physical strength. Adsorbing capacity value of 1.99 mmol·g-1 of the granular adsorbent was equivalent to about 90% of adsorbing capacity of the original TPEX. The granular adsorbent had high break through capacity of about 28 mg asP·g-1 with a flow condition that line velocity was 2.4 m·h-1, and space velocity was 4 h-1. These results suggest that the flow method with the granular adsorbent has the feasibility of effective and simple method that can utilize effectively phosphate adsorption characteristics of TPEX for removing phosphate anions from wastewater or some watersystem.
