Book excerpt: The design specification for monosodium titanate (MST) requires that less than 1 per cent of the particles are larger than 35 micron and that less than 1 per cent of the particles are smaller than 1 micron. Blue Grass Chemical Specialties produced two batches of MST for the Defense Waste Processing Facility (DWPF) that do not meet the particle size specification. The material has more than 1 per cent of the particles smaller than 1 micron. This increase in the fraction of particles less than 1 micron could adversely affect filtration within the Actinide Removal Project (ARP). The authors conducted dead-end filtration testing with 0.45 micron polymeric filter media, 0.5 micron Mott sintered stainless steel filter media, and 0.1 micron Mott sintered stainless steel filter media. The authors make the following recommendations for MST particle size. If a 0.5 micron Mott filter is used for the ARP process, the existing particle size specification (less than 1 per cent of particles less than 1 micron and less than 1 per cent of particles greater than 35 micron) should be maintained. If a 0.1 micron Mott filter is used for the ARP process and the existing particle size specification is not met, DWPF personnel should arrange for filter tests, such as those described in this report, to be performed to evaluate the filterability of the MST. DWPF personnel should consider revising the particle size specification, because technology improvements allow better resolution of particles less than 1 micron. The limited data collected during this testing is not sufficient to change the particle size specification. Limited additional testing similar to that performed here would provide sufficient technical bases.
