Energy efficient vacuum filtration concept

摘要

1. Vacuum filters are used very widely in chemical, metallurgical and mining industry for recovering the final products (precipates, concentrates, valuable metals) 2. In vacuum filters, the driving force for filtration results from the application of suction on the filtrate side of the filter medium » vacuum pump is always needed. 2. It has been estimated that about 2/3 of the operating costs of vacuum filters are caused by the energy required by the vacuum pump. 3. Technology is old (> 100 years) and signifigant improvements have not been introduced lately » very conservative industry 4. There are possibilities to improve the energy efficiency of vacuum filtration processes by utililizing modern measurement and process control technology.
