As part of an overall environmental evaluation of the H-Coal liquefaction process, sour water treatability studies have been performed. These studies conclude that H-Coal Sour Water can be successfully treated for reuse or for discharge to public waters. Zimpro performed the first three studies on the biophysical treatment utilizing Powdered Activated Carbon Treatment (PACT). The PACT studies achieved the following results: five-day Biochemical Oxygen Demand (BOD/sub 5/) removal was greater than 98.8%; Chemical Oxygen Demand (COD) removal was 85 to 87%; essentially complete nitrification was achieved; phenolics removal was greater than 99%; priority pollutants were removed to levels below EPA defined detection limits; PACT operated well using wet air regenerated carbon; and carbon recovery was approximately 90% in the wet air regeneration step.
