Adsorption of organic compounds in water using a synthetic adsorbent

The purpose of this study was to investigate adsorption of trace organic compounds from drinking water by a synthetic resin. In the batch experiments, the treatment efficiency was nearly indiscriminate at every point selected for the resin addition. The adsorption performance could be significantly improved using a high dosage of resin, pH about 8.0, low temperature, and high initial concentration of the organic compounds. In the column experiments, the single column study indicated that the breakthrough time (BT) and volume of the resin bed increased with decreasing flow rate. In the four serial columns study, there was no pronounced relationship between the adsorption capacity of resin and treatment efficiency of organic compounds, and the mean adsorption capacity was about 1.40 gn. The column service time and treated water volumes were almost not affected by the treatment efficiency. Copyright (C) 1997 Elsevier Science Ltd.
