Abstract : Biodegradation and toxicity studies were completed for photographic processing wastewaters generated by the 544th Aerospace Reconnaissance Technical Wing (SAC) Photo Plant at Offutt AFB, Nebraska. Composite samples were prepared from each of the sets and evaluated for biodegradability and toxicity. The toxicity studies were performed by using Pimephales promelas (Fathead Minnows) as test animals and the effluent from a bench-scale activated sludge plant treating the composite photowaste samples. The toxicity of the photowaste composite prepared from the March set of samples was approximately 20 times that of the composite prepared from the September set of samples after treatment, using Pimephales promelas.
