Evaluation of Defense Waste Processing Facility (Dwpf) Glass Samples After an Extended Melter Outage

Abstract

Processing Facility glass samples to support this study; Babb Attaway, Chris Martino, and the Shielded Cells technicians for their support in sample receiving, transfer, and preparation of the samples for analysis; and

Basic Research Needs for Environmental Management

“…The airlift pour spout is the riser pipe that begins at the glass discharge spout indicated on Figure 7; however, it is not currently known how much of each type of crystal can be tolerated in a melter without causing processing problems or limiting the melter lifetime. A conservative limit on crystallinity was adopted by the DWPF that the liquidus temperature (T L) must be less than 1050°C to avoid any crystals (noble metals and their oxides excluded) in the melter (Edwards et al 2006;Fox et al 2014). WTP has constrained the glass composition to produce less than 1 volume percent of crystals at 950°C (Vienna and Kim 2014).…”

Development the Economical Chemical Treatment Plant for Chromium Recovery From Tannery Waste Water

“…Its uptake is limited to 55-70% and the remaining portion is discharged as waste.After tanning a series of operations known as finishing process is carried out to produce different types of leather (oiling, dyeing etc.) [5]. Finishing chemicals are used to creating a certain properties in finished leather like appearance, flexibility, softness, strength, colour which are the requirement of import products of leather.…”
