Chemically inactivated tetanus toxin (tetanus toxoid, TT), purified from cultures of a virulent Clostridium tetani strain, is the active pharmaceutical ingredient of anti-tetanus vaccines. Culture clarification for TT ...

The present work resulted from a study about coolant filtration systems in industries with metalworking process in large scale. The filtration and element filter world markets move billions of Reais per year and have a ...

Many studies related to bag filters have focused on minimizing the amount of energy used in the process. Seeking longer filtration cycles, lower frequency of cleaning cycles and a longer filter life, such studies search ...

The objective of this work was to characterize different fibrous filters after filtration and to evaluate the surface treatment performance of these materials during pulse jet filtration, in the removal of micrometric ...

Water supply in rural communities without access to treatment is a challenge to be overcome. In this perspective, a simple, accessible and easy-to-use technology, such as the domestic biological filter, maybe a viable ...

The particle retention inside a filter medium, after cleaning, significantly improves the initial pressure drop during the subsequent cycle, that is, the residual pressure drop. However, the way as these particles ...
