Filter Plant Design for Asbestos Fiber Removal
Publication: Journal of Environmental Engineering
Volume 109, Issue 4
Abstract
Water filtration plants used to remove asbestos fibers should be designed to produce filtered water with very low turbidity (0.10 ntu or lower). A key design factor in accomplishing this is to provide for flexibility in plant operation, especially with respect to conditioning raw water for filtration. The preconditioning and the filtration should be viewed as interdependent portions of the clarification process, which should be designed to operate at maximum efficiency. Water quality monitoring is very important. Adequate monitoring capability must be provided. Careful control of pH is necessary during coagulation, and filtered water turbidity should be monitored continuously so filters can be backwashed before large amounts of floe and asbestos fibers are discharged from the filter into the treated water. Pilot plant studies as well as design and operation of full scale plants show that producing low turbidity water is attainable for Lake Superior and Cascade Mountain waters. Design data and treatment results are also presented.
