Studies were initiated to determine methods for the removal of lead from the waste water streams at the Sunflower Army Ammunition Plant, Lawrence, Kansas. Two approaches were taken. The first investigated the ion exchange process for lead removal. Using a resin column in pilot plant studies, a reduction of lead in the Sunflower Blender effluent to a level of 0.05 ppm was accomplished. The second approach involved the use of the lead precipitation method in a pilot plant located adjacent to the blender. Lime and ferric salts ferric chloride and ferric sulfate were used to treat the blender waste water. Lead removals of 75 - 85 percent were achieved, to levels as low as 0.30 parts per million. Overall improvement in water quality was also realized with this system. A combination of both systems is recommended for treating waste water streams at SAAP. The lead precipitate system, after removing approximately 80 percent lead and improving the water quality, would discharge into the ion exchange process where the lead levels would be reduced to at least 0.05 ppm.
