Challenges of a feasible route towards sustainability in environmental protection

G. LETTINGA

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 2,   Pages 123-134 doi: 10.1007/s11783-010-0028-1

Abstract: Anaerobic processes for treatment of low and high strength wastewaters and solid wastes constitute the core method in the natural biological mineralization (NBM) treatment concept. When adequately combined with the complementary NBM-systems and modern clean water saving practices in wastewater collection and transport, they represent a feasible route to sustainable environmental protection (EP), in essence even towards a more sustainable society. Despite the development and implementation of modern high rate Anaerobic Wastewater Treatment (AnWT-) systems and complementary innovative NBM-processes, the considerable progress made since the seventies in fundamental insights in microbiology, biochemistry and process technology, still numerous challenging improvements in the NBM-field can be realized. This contribution is mainly based on the insights attained from wide ranging literature evaluations and the results of experimental research conducted by numerous PhD students who participated in our group over the last four decades. An attempt is made here to identify major facets on which an improved insight can, and consequently should, be obtained in order to accomplish more optimal operation and design of various types of Anaerobic Degradation (AnDeg-) processes.

Progress in Macro and Micro Modeling of Solidification Process of Shaped Casting

Liu Baicheng

Strategic Study of CAE 2000, Volume 2, Issue 9,   Pages 29-37

Abstract:

Facing the market economy and global challenge, the development of manufacturing industry, especially casting industry is critical to the national economy. However, there is quite a large technical gap between the casting industries at home and abroad. The views on the future trend of innovative casting technologies are consistent at home and abroad. They are： 1) key technology for manufacturing super large and heavy castings for the national engineering projects, 2) net shape casting technologies, and 3) application of modeling and simulation technology to substitute the traditional trial and error method. To reform the traditional casting industry by using computer technology is one of the hottest research frontiers attracted by many researchers and engineers. Computer simulation of solidification process of shaped casting can assure the quality of casting, optimize the casting technology, shorten the lead time and, therefore, decrease the developing and manufacturing cost. Recently, numerical simulation of mold - filling and solidification processes of casting and the prediction of shrinkage defects, etc. , have been put into application in many casting plants at home and abroad, and great progress in stress analysis and microstructure simulation has been achieved.
