Impact of a Rotary Microfilter on the Savannah River Site High Level Waste System

PDF Version Also Available for Download.

Description

The rotary microfilter is an alternative filter technology that offers increased filter flux over conventional filtration technologies. The filter system combines centrifugation with membrane filtration. Solids are removed from the liquid at the membrane surface, and the centrifugal force acts to keep the surface clean, minimizing the formation of a filter cake. The centrifugal force minimizes solids buildup, allowing more flow through the filter membrane. The effect is the same as increasing the axial velocity of a crossflow filter without increasing system pressure requirements. Centrifugal filter systems are commercially available and have been used in radioactive service both at Los ... continued below

Description

The rotary microfilter is an alternative filter technology that offers increased filter flux over conventional filtration technologies. The filter system combines centrifugation with membrane filtration. Solids are removed from the liquid at the membrane surface, and the centrifugal force acts to keep the surface clean, minimizing the formation of a filter cake. The centrifugal force minimizes solids buildup, allowing more flow through the filter membrane. The effect is the same as increasing the axial velocity of a crossflow filter without increasing system pressure requirements. Centrifugal filter systems are commercially available and have been used in radioactive service both at Los Alamos National Laboratory (LANL) (for Low-Level Waste) and in Russia (for High-Level Waste). The technology has been tested with actual SRS High-Level Waste at the Savannah River Technology Center (SRTC) Shielded Cells. SRTC researchers tested the rotary microfilter as an alternative to the crossflow filters in the current baseline of the Salt Waste Processing Project and the Actinide Removal Project (ARP). The data show significant improvement in filter flux with the rotary microfilter over the crossflow filter. As part of the development of the rotary microfilter, the author investigated the impact of the technology on the Savannah River Site High Level Waste system. This report documents that investigation.
