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...
Drinking water treatment in a gravimetric flow system with TiO2 coated membranes
Bergamasco, Rosangêla; Silva, Flávia Vieira da; Arakawa, Flávia Sayuri; Yamaguchi, Yamaguchi; Reis, Miria Hespanhol Miranda; Tavares, C. J.This paper presents filtration results for drinking water treatment obtained with a commercial cellulose acetate membrane of 0.45 μm pore diameter, with and without TiO2 coating. The deposition of titanium dioxide thin films onto membrane surface was made by pulsed-frequency d.c. reactive magnetron sputtering at room temperature from a high purity Ti target in Ar/O2/N2 atmosphere, at different conditions for ca...
