Description:
The use of synthetic polymeric adsorbents for removal of organic pollutants from industrial waste streams is a viable alternative to more common treatment methods such as carbon adsorption. However, resin technology is not widely practiced due to the difficulty of selecting the appropriate synthetic adsorbent/regenerant combination for a particular application. This research program was undertaken to develop a simple, reliable laboratory test to assess the feasibility of using synthetic resin adsorbents for treatment of a given waste water stream. The new test method facilitates rapid screening of a large number of adsorbent/regenerant pairs. The test consists of exposing small bags of adsorbents in the actual waste stream for predetermined periods of time, followed by regenerating the exposed adsorbents. The batch portion of the test measures regenerated saturation capacity of any adsorbent/regenerant pair with a single analysis. The rate portion measures regenerated capacity as a function of time. Capacity data obtained by the test method were compared and correlated with data obtained by conventional isotherm tests and column experiments. In general, the batch test performs better than the isotherm test in predicting column saturation capacity of polymeric adsorbents.
