Biofilm photobioreactors for the treatment of industrial wastewaters.
(2009) In Journal of Hazardous Materials 161(1). p.29-34- Abstract
- A flat plate and a tubular packed-bed photobioreactor with an algal-bacterial biofilm attached onto Poraver((R)) beads carriers, a flat plate and a tubular photobioreactor with the biofilm attached onto the reactor walls, and an algal-turf reactor were compared in terms of BOD removal efficiencies, elimination capacities, and stability. A control column photobioreactor with suspended algal-bacterial biomass was also tested to compare the performance of biofilm photobioreactors with conventional algal-based processes. When the algal-bacterial biomass was immobilized onto Poraver((R)) the process never reached a steady state due to a poor homogenization in the bioreactor. When the biofilm was formed onto the reactor wall (or reactor base)... (More)

A control column photobioreactor with suspended algal-bacterial biomass was also tested to compare the performance of biofilm photobioreactors with conventional algal-based processes. When the algal-bacterial biomass was immobilized onto Poraver((R)) the process never reached a steady state due to a poor homogenization in the bioreactor. When the biofilm was formed onto the reactor wall (or reactor base) the process was stable. A maximum degradation rate of 295mg BODl(-1)h(-1) was achieved in the algal-turf reactor although control experiments performed in the dark showed atmospheric O(2) diffusion represented 55% of the oxygenation capacity in this system. BOD removal rates of 108, and 92mg BODl(-1)h(-1) were achieved in the tubular and flat plate biofilm reactors, respectively, compared to 77mg BODl(-1)h(-1) in the control suspended bioreactor. In addition, all biofilm photobioreactors produced an easily settleable biomass. Evidence was found that biomass attachment to the reactor's wall improved stability. (Less)
