An effective, simple and low-cost pretreatment for culture clarification in tetanus toxoid production
(Taylor & Francis, 2018-10)
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 ...
Modeling of the efficiency of fibrous filters through numerical simulation and X-ray tomography
(Vsp BvZeistHolanda, 2001)
Sistemas de filtragem aplicados em processos fabris automotivos
(Universidade Estadual Paulista (Unesp), 2014-12-16)
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 ...
Estudo do comportamento da deposição das partículas de diferentes meios filtrantes
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2008-03-17)
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 ...
Sistemas de filtragem aplicados em processos fabris automotivos
(Universidade Estadual Paulista (UNESP), 2015)
Avaliação do desempenho dos tratamentos das superfícies dos meios filtrantes submetidos à filtração por pulso de ar reverso
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2017-03-31)
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 ...
Avaliação da colmatação biológica através da atividade enzimática em filtros lentos intermitentes para uso unifamiliar
(Universidade Federal de Santa MariaBrasilCiências AmbientaisUFSMPrograma de Pós-Graduação em Ciência e Tecnologia AmbientalUFSM Frederico Westphalen, 2021-10-15)
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 ...
Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2006-06-19)
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 ...
The effect of media bed characteristics and internal auxiliary elements on sand filter head loss
(Elsevier Science BvAmsterdamHolanda, 2012)
