GAC ADSORBER DESIGN FOR REMOVAL OF CHLORINATED PESTICIDES

Research is reported which focused on the efficicent and cost-effective appplication of fixed-based granular activated carbon (GAC) adsorbers for treatment of potable water supplies contaminated with alachlor and 1-HC (1-hydroxychlordene). The research involved the following: (1) evaluation of the effectiveness of fixed bed GAC adsorbers for removal of alachlor and 1-HC from water in the presence of high concentrations of background DOM (dissolved organic matter) such as humic substances; (2) investigation of the transformation of heptachlor to 1-HC; (3) development of appropriate equilibrium and rate data for the adsorption of alachlor and 1-HC; (4) investigation of predictive or simulative capability of models for adsorber design; (5) examination of the general applicability of such models for forecasting the performance of adsorber systems; and (6) cost estimation and economic appraisal of the treatment technology.
