“…One reason could be the heterogeneity of biofilms that consists of several microbial groups with different nutritional needs and different interactions types with surfaces; thus, the presence of groups of microorganisms varying these characteristics may change with time in the biofilms (Zacheus et al 2000). The chemical properties of the surface also have been known to directly influence the adhesion and distribution of microorganisms in a biofilm (Johnson et al 1996), which needs to be considered when selecting monitoring materials to use. However, the positive correlation observed between the biomass attached to the different coupons suggests that Average corrosion rate in the carbon steel coupons deposited on the basin of cooling towers supplied with treated recycled water (TRW) or clarified and chlorinated water (CCW) during the course of the experiment.…”

The study was planned to quantify the distribution of bacteria between bulk water and biofilm formed on different materials in an industrial scale cooling tower system of an oil refinery operating with clarified and chlorinated freshwater (CCW) or chlorinated tertiary effluent (TRW) as makeup water. The sessile and planktonic heterotrophic bacteria and Pseudomonas aeruginosa densities were significantly higher in the cooling tower supplied with clarified and chlorinated freshwater (CTCW) (p < 0.05). In the two towers, the biofilm density was higher on the surface of glass slides and stainless steel coupons than on the surface of carbon steel coupons. The average corrosion rates of carbon steel coupons (0.4-0.8 millimeters per year (mpy)) and densities of sessile (12-1.47 × 10(3) colony-forming unit (CFU) cm(-1)) and planktonic (0-2.36 × 10(3) CFU mL(-1)) microbiota remained below of the maximum values of reference used by water treatment companies as indicative of efficient microbial control. These data indicate that the strategies of the water treatment station (WTS) (free chlorine) and industrial wastewater treatment station (IWTS) followed by reverse electrodialysis system (RES) (free chlorine plus chloramine) were effective for the microbiological control of the two makeup water sources.

“…Since minimal adhesion to quartz has been previously observed [56][57][58][59], therefore, quartz substrates were used as the benchmark material for minimal bacterial attachment under the selected solution conditions. The adhesion characteristics of the bacteria suspended in either IS of KCl solutions are shown in Fig.…”

Biofilms have devastating impacts on many industries such as increased fuel consumption and damage to surfaces in maritime industries. Ideal biofouling management is inhibition of initial bacterial attachment. The attachment of a model marine bacterium (Halomonas pacfica g) was investigated to evaluate the potential of these new novel surfaces to resist initial bacterial adhesion. Novel engineered surfaces were generated via breakdown anodization or electrophoretic deposition, to modify three parameters: hydrophobicity, surface chemistry, and roughness. Mass transfer rates were determined using a parallel plate flow chamber under relevant solution chemistries. The greatest deposition was observed on the superhydrophilic surface, which had micro- and nano-scale hierarchical structures composed of titanium oxide deposited on a titanium plate. Conversely, one of the hydrophobic surfaces with micro-porous films overlaid with polydimethylsiloxane appeared to be most resistant to cell attachment.

“…Após a montagem, as colunas foram saturadas, no sentido ascendente delas, com solução iônica de CaCl 2 na concentração de 5,5 g L -1 , próxima à da solução do solo, para que os coloides das amostras de solo não sofressem desestabilização, comprometendo a permeabilidade em razão da diminuição da força iônica (Johnson et al, 1996). O volume da solução de CaCl 2 utilizado para saturação das colunas, até a formação de uma fina lâmina de água no topo dessas, foi utilizado como volume de poros (V 0 ).…”

RESUMOOs principais atributos edáficos relacionados com a lixiviação de naftaleno nos solos consistem na granulometria, no teor de matéria orgânica e na composição mineralógica das frações silte e argila. Este trabalho objetivou determinar os valores da dispersão e do retardamento do naftaleno em amostras de solos coletadas nas proximidades de tanques de armazenamento de combustíveis localizados em Recife, PE. Os experimentos de lixiviação foram realizados em colunas contendo amostras deformadas e foram modelados usando a equação de convecção-dispersão, que foi ajustada aos dados experimentais com o emprego do software CXTFIT 2.0. Os resultados indicaram que solos arenosos oferecem menor resistência à lixiviação de naftaleno e que a presença de goethita, juntamente com a matéria orgânica, é possivelmente o principal fator responsável pelo retardamento do transporte desse composto no conjunto de amostras estudadas.
