Utilização do farelo de conchas de vôngole na adsorção de fósforo e como corret...
Matos, Antonio T.; Eustáquio Júnior, Valdeir; Ribeiro, Ivan C. A.; Teixeira, Denis L.; Lo Monaco, Paola A. V.Teve-se o objetivo de, com a realização deste trabalho, obter a curva de neutralização do pH de amostras dos horizontes A e B de um Latossolo Vermelho-Amarelo distrófico, utilizando-se de farelo de conchas de vôngole (Anomalocardia brasiliana); além disso, avaliar a capacidade de adsorção de fósforo, obtendo-se a isoterma de adsorção de melhor ajuste aos dados obtidos. Verificou-se que o farelo de concha de vôn...
Efeito da adição de diferentes substâncias químicas no extrato de sementes de m...
Matos, Antonio T.; Pereira, Magno dos S.; Eustáquio Júnior, Valdeir; Batista, Ana Paula da S.; Lo Monaco, Paola A. V.; Baker, Sandy A. A.Este trabalho foi realizado em duas fases. Na primeira, objetivou-se avaliar o efeito de diferentes concentrações de sementes de moringa, aplicadas na forma de extrato, na remoção de turbidez de esgoto sanitário. A segunda fase consistiu em avaliar o efeito da adição de diferentes sais (NaCl e KCl) e uma base (Ca(OH)2) no preparo do extrato de sementes de moringa, com a melhor faixa de remoção obtida na fase 1,...
Filtration rates in inorganic filters submitted to different repose periods
Teixeira, Denis Leocádio; Matos, Antonio Teixeira De; Monaco, Paola Alfonsa Vieira Lo; Eustáquio Júnior, Valdeir; Baker, Sandy Athaíde ArcherCom a realização deste trabalho, objetivou-se avaliar a taxa de filtração em filtros orgânicos, após terem sido submetidos a diferentes tempos de pousio, no tratamento primário da água residuária da suinocultura. Colunas de filtragem foram montadas em tubos de PVC de 100 mm de diâmetro e 600 mm de comprimento, tendo sido preenchidas com serragem de madeira, na granulometria de 2-5 mm. Foram avaliados cinco dife...
Efficiency of constructed wetland systems cultivated with black oats treatment ...
Eustáquio Júnior, Valdeir; Matos, Antonio Teixeira De; Monaco, Paola Alfonsa Vieira Lo; Campos, Lidiane Carvalho De; Borges, Alisson CarraroCom a realização deste trabalho, objetivou-se avaliar a eficiência do sistema alagado construído, cultivado com aveia preta forrageira (Avena strigosa Schreb), no tratamento de esgoto domestico, efluente de um tanque séptico, com ênfase na remoção de matéria carbonácea, nutrientes (N, P e K) e sódio. O experimento foi conduzido em quatro Sistemas Alagados Construídos (SACs) de escoamento subsuperficial horizont...
SANITARY SEWAGE TREATMENT USING FILTER FOLLOWED BY COAGULATION WITH MORINGA SEE...
Lo Monaco, Paola Alfonsa Vieira; Matos, Antonio Teixeira de; Vieira, Gustavo Haddad Souza; Eustáquio Júnior, Valdeir; Santos, Magno Pereira dosAmong the forms of primary wastewater treatment, organic flters have stood out due to the high effciency in the removal of pollutants, the low cost of acquisition and the possibility of being submitted to composting after its use.It is aimed was to evaluate the effciency of the fltration process of domestic sewage in gross sawdust, with and without exclusion of the frst two pore volumes, followed by coagulation...
Eficiência do sistema de aeração em cascata no tratamento da água residuária da...
Eustáquio Júnior, ValdeirConselho Nacional de Desenvolvimento Científico e Tecnológico; Due to lack of technical information on the treatment of wastewater using cascade aeration systems, this work aimed to study the performance of this system in the treatment of the wastewater from washing and stripping/pulping coffee (CW). In addition, it sought to determine the coefficient of efficiency associated with cascade aeration system, evalu...
EFFECT OF THE MASS AND FORM OF SEED PROCESSING ON THE COAGULANT POWER OF MORING...
Matos, Mateus Pimentel de; Matos, Antonio Teixeira de; Silva, Edson Faria da; Eustáquio Júnior, ValdeirLittle is known regarding the influence of quality and form of seed processing on the coagulation power of the Moringa seed extract. Thus, this work sought to evaluate the coagulant and xenobiotic power of seeds according to the mass range and its form of processing (shelled or unshelled seeds). For this, surface water with high turbidity, collected in from a reservoir was analyzed. To the samples extracts prep...
Aeration system efficiency of the cascades in the coffee wastewater treatment
Eustáquio Júnior, Valdeir; Teixeira de Matos, Antonio; Alfonsa Vieira Lo Monaco, Paola; Pimentel de Matos, MateusThe issue of this work was to assess the efficiency of aeration systems in cascades for the treatment of wastewater from the processing of coffee fruits. The aeration system was installed in cascades of a level difference of 4.14 m from the ground with 23 steps (height, width and length of 0.18, 0.32 and 0.60 m, respectively.) Samples of influent and effluent, after system operating with three recirculations pe...
Efficiency of constructed wetland systems cultivated with black oats treatment ...
Eustáquio Júnior, Valdeir; Matos, Antonio Teixeira de; Lo Monaco, Paola Alfonsa Vieira; Campos, Lidiane Carvalho de; Borges, Alison CarrroThe objective of the present work was to evaluate the efficiency of a constructed wetland system cultivated with black oat (Avena strigosa Schreb) for the treatment of domestic sewage effluent from a septic tank, with emphasis on removal of carbonaceous matter, nutrients (N, P and K) and sodium. The experiment was conducted in four constructed wetland system (CWS) with horizontal subsurface flow for secondary/t...

Teixeira, Denis Leocádio; Matos, Antonio Teixeira De; Monaco, Paola Alfonsa Vieira Lo; Eustáquio Júnior, Valdeir; Baker, Sandy Athaíde ArcherThis work aimed to evaluate the filtration rate in organic filters after being subjected to different repose periods in the primary treatment of swine wastewater (SWW). Filtration columns were mounted in PVC pipes measuring 100 mm in diameter and 600 mm in length and filled with 2-5 mm sawdust particles. Five different repose periods were evaluated: 1, 2, 4, 8 and 16 days after the first filtration, carrying ou...
