SINTERED METAL FILTER SYSTEMS FOR THE CHEMICAL PROCESS INDUSTRY Dr. Kenneth L. Rubow Louise L. Stange Mott Corporation Presented at 2nd China International Filtration Conference Shanghai, China November 20-22, 2002 1 Mott Corporation INTRODUCTION Filtration systems, utilizing sintered metal media for solids/liquid separation, have proven to be an effective and economical alternative to other separation methodologies, which may be vulnerable to pressure spikes, high temperatures, and / or corrosive environments. These harsh environments, often demanding use of continuous service, are ideally suited for all-metal filtration system utilizing sintered metal media, which have been fabricated into tubular metal elements. Sintered metal media have demonstrated high particle efficiency removal, reliable filtration performance, effective backwash capability, and long on-stream service life in many industrial applications that typically utilize leaf filters, bag filters, and plate and frame filters. Sintered metal media provide a positive barrier to downstream processes. Sintered metal can also be used to support finer filter membranes, precoated, or used as filter septum when they are coated with ion exchange resins. In addition to providing superior filtration in a single pass, clean-in-place backwashing reduces operator exposure to process materials and volatile emissions. While applications include sustained high temperature and corrosive environments, any pressure driven filtration process with high operating costs has the potentia
