Improved Filtration of Wash Water Generated during Bridge Maintenance Painting

摘要

The objective of the research performed in this project was to develop a portable filtration system capable of processing bridge washing wastewater containing particles of lead-bearing paint. The system was to have the capacity to treat/handle the entire wastewater flow of a typical bridge overcoating project, and to be capable of reducing the total lead content of the wastewater to the extent that it could be safely discharged to receiving waters or onto the ground. Ideally, the system would be able to reduce the total lead content of the wastewater to a concentration equal to or less than the Federal drinking water standard.
