Abstract |
The City of Helena, Montana uses an activated bio-filter (ABF) process for secondary treatment of its wastewater. The biological process consists of a redwood tower (bio-cell) and a short-term aeration unit. The ABF process is relatively new, and full-scale performance information at design loadings was not available. The primary objective of this research effort was to develop process operation and performance information at loadings near the manufacturer's recommended design criteria during the winter months of the year. Other objectives were to determine system energy requirements and system sludge production values. |
