Água de abastecimento com elevada turbidez: eletrocoagulação/flotação como pré-tratamento em estações de tratamento de água
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-08-17)
Freshwater sources, surface (rivers, lakes) or groundwater, are generally used as resources for water supply. In order to the water to be distributed, treatments that aim at its ―safety‖ regarding aesthetic qualities, ...
Optical properties of highly turbid shallow lakes with contrasting turbidity origins: The ecological and water management implications
(Academic Press Ltd-elsevier Science Ltd, 2013-11-30)
A comprehensive optical study of three highly turbid shallow lakes was presented. The lakes contained very high concentrations of optically active substances [OASs] with clear differences in total suspended solid [TSS] ...
A simplified approach to address turbulence modulation in turbidity currents as a response to slope breaks and loss of lateral confinement
(Springer, 2014-04-01)
Turbidity currents traversing canyon-fan systems flow over bed slopes that decrease in the downstream direction. This slope decrease eventually causes turbidity currents to decelerate and enter a net-depositional mode. ...
Microbial safety and quality evaluation of UV-Treated, cold-pressed colored and turbid juices and beverages
(2018)
The growing demand for fruit and vegetable juice blends, with improved nutritional and sensory attributes, has prompted the industrial adoption of nonthermal processing technologies, including UV light. Limited studies ...
Turbidity matters: differential effect of a 2,4-D formulation on the structure of microbial communities from clear and turbid freshwater systems
(Elsevier, 2019-08)
We evaluated the effect of AsiMax 50®, a commercial formulation of 2,4-D (2,4-dichlorophenoxyacetic acid), on the structure of both micro + nano phytoplankton (>2 μm; species composition and abundance) and cytometric ...
Changes in the phytoplankton structure in a Pampean shallow lake in the transition from a clear to a turbid regime
(Springer, 2014-08)
We analysed the changes in phytoplankton and in the main limnological features in a shallow lake during its transition from a clear-vegetated regime to a turbid one from 2005 to 2013. As samplings were discontinuous, data ...
Flotação por ar dissolvido na clarificação de águas com baixa turbidez utilizando sulfato de alumínio e sementes de Moringa oleifera como coagulantes
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia QuímicaPesquisa e Desenvolvimento de Tecnologias Regionais, 2008-12-22)
This work aims to investigate the process of Dissolved air Flotation (DAF) for clarifying water samples with low turbidity using aluminum sulphate and Moringa oleifera seeds as coagulants. The experimental procedure was ...
Effect of pH and ionic strength on apple juice turbidity: Application of the extended DLVO theory
(Elsevier, 2007-12)
This work studied the effect of liquid medium pH and ionic strength on the stability of apple juice particles. Colloidal interactions between them were modeled with the extended DLVO theory. Considering that repulsive ...
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 ...
