A poly-epsilon-caprolactone based biofilm carrier for nitrate removal from water
Rodrigues, A. L.; Machado, A.; Nobrega, J. M.; Albuquerque, Antonio; Brito, A. G.; Nogueira, ReginaNitrate removal from water has been accomplished by heterotrophic biofilms using organic carbon as a source of reducing power. To overcome the natural limitation in organic carbon in water, a poly-epsilon-caprolactone based biofilm carrier that serves simultaneously as a biofilm carrier and as a source of organic carbon was developed and tested in the present work. The feasibility of the new biofilm carrier for...
Effect of vegetation on the performance of horizontal subsurface flow construct...
Mesquita, Maria da Conceição; Albuquerque, Antonio; Amaral, Leonor; Nogueira, ReginaThis research evaluates the effect of both organic and ammonia loading rates and the presence of plants on the removal of chemical oxygen demand and ammonia nitrogen in horizontal subsurface flow constructed wetlands, 2 years after the start-up. Two sets of experiments were carried out in two mesocosms at different organic and ammonia loading rates (the loads were doubled); one without plants (control bed), the...
