(2020-11-01)
Nowadays, the Polyethylene Terephthalate (PET) bottle, which is a post-consumer product, has generated a strong interest in the environmental consequences that surround it, and a suitable alternative is to incorporate it ...
Turbidity control on dissolved air flotation process using fuzzy logic
(2018)
© IWA Publishing 2018. This study intends to explore fuzzy logic control on clean water turbidity process with dissolved air flotation (DAF). Three different strategies were tested to regulate clean water turbidity by ...
A semi-closed loop microalgal biomass production-platform for ethanol from renewable sources of nitrogen and phosphorous
(Elsevier, 2019-05)
Production of microalgal biomass for feed and fuels demands unsustainable large amounts of fertilizers. The most broadly considered alternative sources of nutrients/fertilizer for microalgae are wastewater and internal ...
Estudo da influência do modo de aeração de uma válvula loop-seal na operação de um leito fluidizado circulante
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia MecânicaUTFPR, 2019-09-12)
The study of the hydrodynamics behavior inside CFB units either to improve the performance of current processes or to develop new applications still deserves the attention of researchers. In particular, efforts have been ...
