Development of a prototype for the treatment of ater contaminated with glyphosate
Santos, Julio Cesar Maciel; Rubio, Andressa Jenifer; Sousa, Jean Carlos Araujo de; Almeida, Ana Carolynna Severo; Bergamasco, RosângelaOne of the current challenges is to meet the demands for quality water since the contamination of bodies of water has been intensified in the last years with the increase in the use of pesticides. Therefore, finding a way to remove contamination by pesticides from water becomes a relevant work. In this study, it was presented the design and construction of a pilot-scale batch reactor prototype in order to remov...
Removal of the herbicide Glyphosate using activated carbon impregnated with met...
Rubio, Andressa Jenifer; Bergamasco, Rosângela; Yamaguchi, Natália UedaWith the increasing use of several pesticides in agriculture, including the Glyphosate which is the herbicide most widely consumed worldwide, there is a need for the development of diversified and effective water treatment, since glyphosate consumption can cause serious health problems on animals, humans and plants. As an alternative treatment, the removal of glyphosate from the water can be obtained with the u...
Effects of coconut granular activated carbon pretreatment on membrane filtratio...
Silva, Flávia Vieira da; Yamaguchi, Natália Ueda; Lovato, Gilselaine Afonso; Silva, Fernando Alves da; Reis, Miria Hespanhol MirandaThis study evaluates the performance of a polymeric microfiltration membrane, as well as its combination with a coconut granular activated carbon (GAC) pretreatment, in a gravitational filtration module, to improve the quality of water destined to human consumption. The proposed membrane and adsorbent were thoroughly characterized using instrumental techniques, such as contact angle, Brunauer–Emmett–Teller) and...
Application of modified membranes in drinking water treatment
Silva, Flávia Vieira da; Yamaguchi, Natália Ueda; Vieira, Angelica M. Salcedo; Amorim, M. T. Pessoa de; Tavares, C. J.; Tavares, Célia Regina GranhenThis paper presents filtration results obtained with commercial acetate membrane with a pore diameter of 0.45 μm, unmodified and modified with TiO2, bearing in mind drinking water treatment. The experimental filtration set-up that was used consisted in the gravitational filtration system, whereas the accomplished tests that were endured consisted of hydraulic permeability of the modified and unmodified membrane...
