| Abstract |
For nontoxic wastes a pricing system was developed for allocating actual cost in proportion to the marginal costs associated with volume and the weight of selected contaminants. The pricing method can be used for separate allocations of capital cost and operating and maintenance cost. Digital simulation models developed for preliminary design of wastewater treatment systems can be used in estimating marginal costs for volume and weight of major contaminants. Copper affected unit operations and unit processes of the activated sludge treatment. Activated sludge was capable of retaining a significant portion of the applied copper. The efficiency of the activated sludge aerator and final settling units were a function of copper concentration, mixed liquor suspended solids, organic loading and the overflow rate. |
