Abstract

Studies have reported the incorporation of microorganisms into cement to promote the formation of calcium carbonate in cracks of concrete, a process known as biomineralization. The paper aims to improve the process of the cascade system for biomineralization in cement by identifying the best hydrodynamic conditions in a reaction cell in order to increase the useful life of concrete structures and, therefore, bring energy and environmental benefits. Two central composite rotatable designs were used to establish the positioning of the air inlet and outlet in the lateral or upper region of the geometry of the reaction cell. The geometries of the reaction cell were constructed in SOLIDWORKS®, and computational fluid dynamics was performed using the Flow Simulation tool of the same software. The results were submitted to statistical analysis. The best combination of meshes for the simulation was global mesh 4 and local mesh 5. The statistical analysis applied to gas velocity and pressure revealed that air flow rate was the factor with the greatest sensitivity, with R2 values up to 99.9%. The geometry with the air outlet and inlet in the lateral region was considered to be the best option.

Abstract

The production of cement accounts for 5 to 7% of carbon dioxide emissions in the world, and its broad-scale use contributes to climate imbalance. As a solution, biotechnology enables the cultivation of bacteria and fungi for the synthesis of calcium carbonate as one of the main constituents of cement. Through biomineralization, which is the initial driving force for the synthesis of compounds compatible with concrete, and crystallization, these compounds can be delivered to cracks in concrete. Microencapsulation is a method that serves as a clock to determine when crystallization is needed, which is assisted by control factors such as pH and aeration. The present review addresses possibilities of working with bioconcrete, describing the composition of Portland cement, analysis methods, deterioration, as well as environmental and energetic benefits of using such an alternative material. A discussion on carbon credits is also offered. The contents of this paper could strengthen the prospects for the use of self-healing concrete as a way to meet the high demand for concrete, contributing to the building of a sustainable society.

Abstract

Anthropogenic and natural actions cause internal and external fractures in concrete. To recover these structures, bio-concretes have been developed with bacteria of the genus Bacillus. These microorganisms consume calcium lactate, synthesize calcium carbonate and biomineralize CaCO3 crystals within the structures of concrete. The aim of the present study was to construct equipment, denominated “Cascade System for Biomineralization in Cement” (CSBC), to determine the limiting velocity of the biomineralization of CaCO3. The construction of the equipment took into consideration chemical and biochemical phenomena responsible for biomineralization. Parts made with 3D printing and a circuit with Arduino UNO R3 board were used in the assembly of the system. The prototype proved to be stable and can be considered a promising tool for future application in research of the regeneration of reinforced concreted in a practical, fast and economical way, especially to the energy sector.

Abstract

A presente pesquisa teve como objetivo a aplicacao do po da semente da planta denominada Moringa Oleifera Lam, a partir do processo de maceracao dessa semente, juntamente com a radiacao solar, no tratamento de agua utilizada para o consumo humano. Neste trabalho foram coletadas amostras de agua em diferentes pocos artesianos, localizados no municipio do Cabo de Santo Agostinho/PE, situados nas praias de Enseada dos Corais e Gaibu, bem como, no Bairro de Ponte dos Carvalhos, sendo realizadas analises fisico-quimicas e microbiologicas, para determinar o poco que seria realizado esse tratamento previo, monitorando, principalmente, a sua eficiencia na remocao bacteriana. Dois tipos de planejamentos experimentais foram realizados, o primeiro usando um fatorial completo 2 3 , com 2 niveis e 3 fatores, a fim de avaliar a influencia dos parâmetros: Concentracao do po da semente da Moringa Oleifera (C M ) em (g.L -1 ), o tempo de exposicao da radiacao solar (t) em (h) e o potencial Hidrogenionico (pH), no que se refere a variavel resposta para DBO (Demanda Biologica de Oxigenio) e DQO (Demanda Quimica de Oxigenio). Assim como, coliformes totais e coliformes termotolerantes, em especial a Escherichia coli. Nos demais ensaios, o planejamento fatorial completo 2 2 , com dois niveis e dois fatores, mostrou duas variaveis independentes: 1) a (C M ) em (g.L -1 ) e o (pH) e 2) o (t) em (h) e o (pH). As variaveis dependentes para as analises fisico-quimicas tambem foram: DBO (mg.L -1 ) e DQO (mg.L -1 ). Assim como, para as analises microbiologicas foram: coliforme totais (UFC.mL -1 ) e coliformes termotolerantes ( E. coli ) (UFC.mL -1 ). O ensaio utilizando os fatores: t=10 h, C M = 2 g.L -1 e pH= 6apresentou menor valor de DQO igual a 7,3 e DBO igual a 2,8 mg.L -1 e mostrou ser o melhor, embora ainda precisa ser mais reduzido esses valores e analisado para o uso apenas com a radiacao solar. Entretanto, o ensaio utilizando os fatores: t=4 h e pH= 6, fixando C M = 2 g.L -1 ,do planejamento 2 2 , foi o que apresentou ser o mais satisfatorio para essa etapa do planejamento, com valores iguais a zero, tanto para coliformes totais quanto para E. Coli . Os resultados encontrados mostraram-se satisfatorios na eliminacao dos coliformes termotolerantes, mas especificamente a bacteria Escherichia coli . Entretanto, na eliminacao de bacterias Coliformes presentes nas amostras apenas a radiacao solar demonstrou eficiencia.

Abstract

The maximisation of the production of metabolites of industrial interest from fermentative processes, such as biosurfactants, requires standardisation of the medium and the cultivation conditions. In this sense, experiments were conducted to maximise the production of the biosurfactant from Candida lipolytica UCP0988 cultivated on 5% animal fat and 2.5% corn steep liquor using a 23 full factorial design. The effects and interactions of the agitation speed (200, 300 and 400 rpm), the variables aeration (0, 1 and 2 vvm) and time of cultivation (48, 96 and 144 h) on the surface tension, yield and biomass were evaluated. The results showed that the variable time of cultivation had positive influence on the production of biosurfactant, while the increase of the variables aeration and agitation showed a negative effect. These results indicate that the biosurfactant has a strong potential to be applied as a clean-up of oil spills at sea and on shorelines.

Abstract

A Direct Contact Thermal Treatment (DiCTT) process was developed in this study, whereby the optimal conditions were identified for the thermochemical oxidation of phenol in a pilot plant. The following operational parameters were considered: the molar stoichiometric ratio of phenol/hydrogen peroxide (R) at a constant feed flow rate of the liquid effluent constant of (QL) = 170 L h−1; the power dissipated by the burner (P) of 38.6 kW at 10% excess air (E); an initial phenol concentration (Cph0) of 500 mg L−1 and a combustion gas recycling rate (VR) of 50%. The thermochemical oxidation of phenol was monitored from oxidative degradation to the mineralization of the organic compound and the formation of acids; phenolic intermediates formed during the oxidative process were analysed. The concentrations of phenol, catechol, hydroquinone and para-benzoquinone were monitored by High Performance Liquid Chromatography (HPLC), Total Organic Carbon (TOC) was measured with a TOC analyser and the hydrogen potential (pH) was measured using a pH meter. Artificial Neural Networks (ANNs) were also used to model the experimental degradation results of the organic pollutant from the DiCTT process. For the ANN modelling, “Statistic 8.0” software was used with a “Neural Networks” module to predict the phenol concentration as a function of time. An R value of 75% was identified as the optimal condition for complete phenol degradation and a TOC conversion of approximately 60%; these rates are satisfactory for phenol degradation, although mineralization rates could be improved. The ANN modelling predictions for the phenol concentration as a function of time showed that the data were best described by a regression model in the form of a Multi-Layer Perceptron (MLP) network. The MLP consists of three layers with two neurons in the input layer, 7 neurons in the hidden layer and three neurons in the output layer. The correlation coefficients (R2) between the network predictions and the experimental results were greater than 0.99, indicating that the model was satisfactory.

Abstract

Scales and sludge generated during oil extraction and production can contain uranium, thorium, radium and other natural radionuclides, which can cause exposure of maintenance personnel. This work shows how the oil content can influence the results of measurements of radionuclide concentration in scale and sludge. Samples were taken from a PETROBRAS unit in Northeast Brazil. They were collected directly from the inner surface of water pipes or from barrels stored in the waste storage area of the E&P unit. The oil was separated from the solids with a Soxhlet extractor by using aguarras at 90+/-5 degrees C as solvent. Concentrations of 226Ra and 228Ra in the samples were determined before and after oil extraction by using an HPGe gamma spectrometric system. The results showed an increase in the radionuclide concentration in the solid (dry) phase, indicating that the above radionuclides concentrate mostly in the solid material.

Abstract

Concrete cracks can induce the disruption of dams, bridges, tunnels, and some structures that assist the human life. The agglomeration component of the concrete and the most applied compound, the Portland Cement, can be utilized in combination with calcium lactate and the Bacillus bacteria to produce the crystals of CaCO3 (raw material of the cement production) through adsorption, biomineralization, and crystallization, reducing the risk of ruptures. Thus, a screening of the biotechnological potential of bacterium Bacillus cereus (UCP 1615) under a concentration of 107 cells/mL was carried out to evaluate the production of CaCO3 crystals with 20 g of the Portland Cement II (PC-II), and 0,58, 1,00, and 1,42 g of calcium lactate. These Petri Dishes were incubated at 28°C and during 168 h. Besides, the crystals produced the B. cereus were analysed by an X-Ray Diffractometer (XRD) to estimate the relation (%) between the mainly and possible components. After 17 h, some crystals had already started to appear in the Petri Dishes of 1,00 and 1,42 g of calcium lactate, and after 168 h, the crystals were scraped of all Petri Dishes. The diffractometric analyse of the condition with the highest lactate condition, of 1,42 g, presented percentages of 82% SiO2 (basic structure of cement) and 18% CaCO3. Therefore, the B. cereus strain shows a biotechnological potential to produce crystals of CaCO3 and that this bacterium is able to be tested under different conditions of calcium lactate, microbial concentration, and water according to a factorial design. Keywords: Concrete cracks. Calcium Lactate. Crystals. XRD.
