Abstract
The California Department of Health Services in cooperation with the California Department of Fish and Game developed and implemented a chlorine optimization study of eight wastewater treatment plants in northern California. Two mobile units were constructed for the project: a pilot chlorination plant and a mobile toxicity testing and water quality laboratory. The pilot chlorination plant tested several optimized chlorination design criteria against existing wastewater treatment plant chlorination systems. The mobile laboratory evaluated the toxicity of the optimized and existing chlorinated effluents. The toxicity associated with the existing unchlorinated and dechlorinated effluents increased with un-ionized ammonia concentrations. Most of the toxicity associated with the unchlorinated and dechlorinated effluents, however, was the result of an artificial increase in pH created by a toxicity test design problem. The optimized chlorinated effluents, with one exception, had lower and more stable chlorine residuals than did the existing chlorinated effluents and hence, were generally less toxic. The toxicity of all effluents investigated increased proportionately with increased chlorine residual.
