Abstract |
The main purposes of the manual are to examine situations that necessitate upgrading of existing municipal wastewater treatment plants and to discuss and evaluate the corrective actions that are required to upgrade these existing plants. Upgrading to overcome organic and hydraulic overloadings and/or to meet more stringent treatment requirements is considered. The information presented is specifically adapted to plants having capacities of less than 5 mgd. The manual emphasizes that operational improvement and modifications to existing unit operations be considered as the logical initial approach to upgrading existing treatment plants. It examines in depth the capabilities, limitations, and interrelationships of the various unit processes. The operation and maintenance requirements of the upgraded treatment plants are also briefly examined. |
