Proper characterization is essential for assuring that wastes meet any treatment or disposal site waste acceptance criteria (WAC). In addition characterization is vital for proper preparation of shipping papers for transporting the waste for treatment or disposal. Process knowledge was inadequate for characterization of legacy waste items from two sites involved in the Melton Valley Decontamina...

Large quantities of biological waste are generated at various steps within the food production chain and a great utilization potential for this solid biological waste exists apart from the current main usage for the feedstuff sector. It remains unclear how the usage of biological waste as compost modulates plant metabolites. We investigated the effect of biological waste of the processing of co...

A full scale swine (300 pigs) waste treatment system, including a solid/liquid separation unit (3 m) with a solids holding tank (1.2 m) and a liquid holding tank (20 m), two anaerobic reactors (10 m each) in series, an intermittent aeration unit (20 m), a sedimentation/polishing unit (20 m) and a sludge dewatering bed (17 m), was used to investigate the impact of integrating an intermittent aer...

One approach to reduce nutrient losses from livestock farms is to apply biological waste treatment systems such as biological nitrogen (N) removal or enhanced biological phosphorus (P) removal (EBPR) to reduce the nutrient content of land-applied waste. The EBPR process takes advantage of the ability of P-accumulating organisms (PAOs) to sequester excess P as polyphosphate granules in their cyt...

In 1973, the Japan Atomic Energy Industry Forum published a report entitled “A closed system for radioactivity”. The report pointed out the importance of R&D for P&T of long-lived nuclides as long-term efforts in developing a complete system for radioactive waste management. JAERI started the development of partitioning process for high-level liquid waste and the design study of transmutation s...

This paper presents experimental results of an inherently safe liquid cooling system. A test rig is operated at Hamburg University of Technology in order to prove the concept and gather first data for electronics cooling in modern civil aircraft. The cooling system uses a dielectric working fluid for the natural circulation in a looped thermosyphon operating in both oneand two-phase mode. First...
