Description:
A prototype system was designed and developed to slurry buoyant activated carbon into a static body of water. The process was developed to remove spilled soluable hazardous compounds from a watercourse. In a simulated spill, up to 98% removal of Diazinon, an organophosphorus pesticide, was achieved by adsorption on activated carbon and by dispersion of the spilled material. The basic system was barge-mounted with an intake pump, a jet-slurrier, a surge tank, and a slurry pump. The buoyant carbon was fed into the slurrier by gravity from a floating, hopper-bottom tote bin. Since no acceptable buoyant activated carbon is commercially produced in the United States at this time, a method of making buoyant activated carbon by using microballoons and a carbon coating mix was developed. Estimated cost per pound of media was $3.50 on a small-batch basis.
