COMPUTER-BASED ENVIRONMENT FOR WASTE-WATER TREATMENT-PLANT DESIGN

Abstract

A prototype computer-based design environment was developed to facilitate wastewater treatment plant design tasks. The design environment includes several mathematical techniques, interactive graphic displays, and user-friendly interfaces. The mathematical techniques are mass and water balances for an analysis program for plant design and a rule-based system for evaluating the likelihood of sludge bulking. A processor is also used to check a given design using existing design standards. The interactive graphic displays and the user interfaces are intended to provide a user-friendly environment for manipulating data, models, and solutions. Sensitivity analyses can be performed for models as well as parameters. The features of the computer-based system are described, and suggestion for extensions are given.
