Data for projecting process capabilities of attached growth biological wastewater treatment systems and procedures for making design calculations are presented in the report. Carbonaceous oxidation (secondary treatment) and single stage nitrification design examples are given. Information for estimating average construction costs and operation and maintenance requirements are presented for typical wastewater treatment plants ranging in size from 1 to 100 mgd capacity. Estimated average construction costs and operation and maintenance requirements for individual unit processes are related graphically to appropriate single parameters for each component. Construction costs are broken down into labor and materials components; operation and maintenance requirements are given for labor, energy, and maintenance materials and supplies. The data in the report provide a means of estimating anticipated average performance and costs for facilities.
