TREATMENT OF A WOOD PRODUCTS SUPERFUND WASTE-WATER - A CASE-STUDY

This paper reports the results of studies designed to determine the treatability of wastewater from a wood products Superfund site using conventional technologies. The treatability studies consisted of a series of filtration pretreatment experiments using different types of filter media to remove suspended solids and emulsified floating oils and grease prior to batch and continuous activated carbon adsorption experiments to remove semi-volatile organics from the wastewater. The results indicated that adequate suspended and emulsified solids removal efficiences were obtained prior to carbon adsorption. Continuous activated carbon experiments resulted in excellent removal of the most prevalent organics of interest. The results of the experiments were instrumental in establishing baseline design data for full-scale implementation of a remediation system.
