Abstract In the course of the U.S. Department of Energy’s (DOE) tank waste retrieval, immobilization, and disposal activities, high-level waste transfer lines have the potential to become plugged. In response to DOE’s needs, Florida International University’s Hemispheric Center for Environmental Technology (FIU-HCET) is studying the mechanism and behavior of pipeline plugging to determine the pipeline operating conditions for safe slurry transport. Transport behavior of multi-species slurry has been studied in a 1-in O.D. pipeline flow loop. The slurry was a five-species mixture of Fe2O3, Al2O3, MnO2, Ni2O3, and SiO2, which simulated actual waste at the Savannah River DOE site. The relationship between the pressure drop in the straight horizontal sections of the flow loop and the mean slurry flow velocity was determined for two solids volume concentrations of 5.2 and 7.8%. Critical deposition velocity was measured from visual observations. An existing empirical model that predicts the pressure gradient for a single-species slurry flow in a horizontal pipeline was used to describe the pressure drop data.

In response to growing importance of household waste management issue, this article deals with the positioning of household waste transfer points from a government-organized waste perspective. By taking Surakarta, a municipality in Central Java, Indonesia as an example, the problem in the municipality is formulated as an MILP, is approached with a capacity-weighted set covering method, and finally is solved by using software LINGO 11. The article concludes that the transfer point alternatives of Sondakan Kuburan, Norowangsan, SPSA, Pajang Rel, Bonoloyo and Kedung Tungkul should be selected in order to be able to serve all the household waste producers for the maximum household waste generated. On the contrary, the selection of Sondakan Kuburan, Bonoloyo and Kedung Tungkul only should be able to provide service to all of the household waste produced for the scenario of minimum amount of household waste.
