Application of tubular ceramic ultrafiltration membranes for the treatment of integrated textile wastewaters

Barredo Damas, Sergio; Alcaina Miranda, María Isabel; Iborra Clar, María Isabel; Mendoza Roca, José Antonio (Elsevier, 2012-06-01)

Membrane technologies have emerged as one of the best suitable alternatives for the management of highly polluted effluents generated in the textile industry processes. These technologies are capable either of being used ...
Effect of pH and MWCO on textile effluents ultrafiltration by tubular ceramic membranes

Barredo Damas, Sergio; Alcaina Miranda, María Isabel; Iborra Clar, María Isabel; Mendoza Roca, José Antonio; Gemma, Matteo (Taylor & Francis, 2011-03)

Textile industries are considered as one of the most polluting among all the industrial sectors. Therefore, the disposal of textile effluents without the appropriate treatment entails high environmental risks. Moreover, ...
Evolution of Membrane Performance During the Ultrafiltration of Reactive Black 5 Solutions: Effect of Feed Characteristics and Operating Pressure

Alventosa de Lara, Elena; Barredo Damas, Sergio; Alcaina Miranda, María Isabel; Iborra Clar, María Isabel (Aidic Servizi, 2012)

[EN] In the present work, the feasibility of the ultrafiltration (UF) technology for the removal of a hazardous azo reactive dye, Reactive Black 5 (RB5), was studied. A tubular UF ceramic membrane was used to filter RB5 ...
