| Abstract |
A continual adsorption-biological regeneration cycle of the activated carbon beds treating a dyehouse effluent has been achieved over a four-month period, resulting in a continuous decolorization and organic reduction. The textile dye wastes can be easily decolorized by a single pass flow through fixed granular activated carbon beds at an average flux of 12 gpm/sq ft, provided that the color bodies are receptive to carbon adsorption. The exhausted carbon can then be regenerated biologically provided that the adsorbate is biodegradable. Biological regeneration provided an adsorption capacity in excess of 1.6 lbs COD per lb of carbon, in this instance. Color removal was virtually complete at the two flow rates evaluated. A 1.0 mgd plant was designed. For 50% COD removal estimates were $230,000 for construction and 8.3 cents/1000 gallons for operation. For 75% COD removal, the estimates were $550,000 and 23.1 cents/1000 gallons respectively. |
