As the Army faces increasing reductions in budget and personnel for supporting functions such as operation and maintenance (O&M) of wastewater treatment plants (WWTPs), it is clear that reliance on automation will continue to grow. While computer systems will not replace operators, they will provide valuable assistance in optimizing the operator's time and effort.An emerging technology with potential application to WWTP O&M is artificial intelligence (AI)/expert systems. These systems use knowledge bases developed by experts in a given field combined with a "reasoning" chain of logic to provide diagnostic and control functions. This study has investigated opportunities for exploiting Al and expert systems for increasing the performance and reducing the cost of Army WWTP O&M. In addition, a general orientation to the technology has been provided to assist Army personnel in making decisions about its applicability to their installations.Findings suggest that Ai/expert systems technology is D T IC not yet at an economically practical level for use in O&M
A shower wastewater recycling system is investigated for potential military use under conditions of limited water supply. Results are reported for laboratory tests on the proposed system. Parameters measured in the tests include those specified by the Office of the Surgeon General (OTSG) in the Interim Quality Criteria for direct reuse of water as well as several others of concern.The laboratory test results show that the wastewater recycling system merits further investigation and development. The proposed system is compatible with existing Army facilities and equipment and is portable. Wastewater can be treated to a quality meeting OTSG standards. Several recycles are possible, with 85 percent of the wastewater recoverable for reuse. No harmful contaminants were detected in any of the test samples.Approved f'or public rclease; distribution is unlimited.The conltents of this report ate not to be used for advertising, publication, or promotional purposes.
