Technical Bulletin No. 0870: Investigation of Advanced Techniques to Remove Low-Level Mercury from Pulp and Paper Mill Effluents

Bench-scale studies evaluated the capability of granular activated carbon adsorption (GAC), ion exchange (IX) with three IX resins, reverse osmosis (RO), nanofiltration (NF), and iron coprecipitation (ICOP) to remove mercury and other metals from a bleached kraft mill effluent. Mercury is of particular concern because the Great Lakes Initiative (GLI) mercury water quality criterion is so low (1.3 ng/l).
