Simulation Tools for Hazardous Waste Removal*

چکیده
The primary mission of Oak Ridge National Laboratory (ORNLj during World War I1 was the processing of pure plutonium metal in support of the Manhattan Project. By-products of this process include radioactive cesium-1 37 and strontium-90. Between 1943 and 1951, the Gunite and Associated Tanks (GAAT) at ORNL were built to collect, neutralize, and store these byproducts. Currently, twelve gunite tanks and four stainless steel tanks are located on the ORNL complex. These tanks hold approximately 75,000 gal of radioactive sludge and solids and over 350,000 gal of liquid. Characterization studies of these tanks in 1994 indicated that the structural integrity of some of the tanks is questionable. Consequently, there is a potential threat to human health through possible contamination of soil and groundwater. These risks provided the motivation for remediation and relocation of waste stored in the ORNL

Removal of hazardous reactive blue19 dye from aqueous solutions by agricultural waste
Low-cost grapefruit peel (Agricultural Waste) was used for removal of reactive blue19 dye fromaqueous solutions. The process was studied as a function of contact time, initial dye concentration andpH. Adsorption process was attained to the equilibrium within 45 min for initial dye concentrations of 50,75, and 100 mg L-1. An acidic medium was the optimum condition for adsorption of dye at roomte...
متن کاملA Prototype System for Automated Sorting and Removal of Bags of Hazardous Waste
In this paper, we present a low-cost vision based system for handling of hazardous waste in an unstructured environment. The prototype system described shows the feasibility of sorting and removal of randomly mixed and oriented flexible objects from a bin using inexpensive and widely available hardware. Our experiments show that the utilization of even the simplest constructs is sufficient for ...
