| ABSTRACT Anaerobic biodigestion is an appropriate alternative for the treatment of swine wastewater due to its biogas generation properties and the possibility of its application as a source of energy for heating or electricity. However, digestate can still contain high levels of turbidity, organic carbon and nutrients and must be correctly managed as a biofertilizer, or treated to avoid any impact on the environment. Considering this, electrocoagulation (EC) shows promise as a technology because of its ease of handling and high efficiency in effluent remediation. This study aimed to evaluate the performance of EC in a batch system in the treatment of swine wastewater digestate. The wastewater used in the treatment was sampled from a 10 m3 biodigestor... |

| ABSTRACT: This study aimed to evaluate the effects of adding probiotic culture (Bifidobacterium animalis subsp. Lactis Bb-12) and prebiotics (fructooligosaccharide - FOS) to yoghurt formulations stored at 4°C for 28 days, using an experimental design (independent variables: (0-3% of FOS and probiotic starter cultures 0-3%). The pH, acidity, fat, syneresis, protein, ºBrix, sugars, FOS and probiotic bacteria count were analyzed. The probiotic- and prebiotic-added yoghurt formulations showed lower acidity, syneresis and glucose than the control yoghurt and compared to formulations containing probiotic and prebiotic separately. The 3% probiotic and prebiotic formulation showed a lower loss of concentration of FOS, and after 28 days presented 1.5g of FOS per... |

| Neste trabalho, apresenta-se um novo material adsorvente, obtido a partir da pirólise de resíduos da erva-mate. O carvão resultante demonstrou elevada área superficial específica quando comparado com outros materiais pirolisados e elevada capacidade de remoção de contaminantes orgânicos de soluções aquosas. Os valores de área específica apresentados pelos materiais foram de 344, 191 e ~0,5 m² g-1, para o carvão Mate 1, Mate 2 e Mate 3, respectivamente. As isotermas de adsorção mostraram que os carvões apresentam potencial para utilização como adsorvente para compostos orgânicos, tais como: o corante têxtil vermelho reativo, o corante azul de metileno e para o herbicida atrazina, sendo que os máximos de adsorção utilizando o carvão Mate 1 foram de 16, 230 e... |
