Acetate Depletion in Horizontal Rotating Tubular Bioreactor
Horizontal rotating tubular bioreactor (HRTB) is a combination of a "thin-layer bioreactor" and a "biodisc" reactor. The interior of a HRTB is characterised by O-ring shaped discs, which together with an internal bioreactor surface, are supposed to serve as carriers for microbial biomass. The performance of a HRTB was investigated in unsterile conditions. Acetate solution supplemented with a nitrogen source, phosphate and some trace elements were used as a growth medium supporting the growth of a mixed culture of microorganisms. Thus, acetate depletion by the action of a mixed culture in aerobic conditions was chosen as a model process. In a wide range of process parameters (acetate inlet concentration in the range 1.4 and 2.9 g L^ -1, medium inlet flow rate in the range 1.0 - 6.5 L h^ -1 and constant bioreactor rotation speed 10 min^ -1) were investigated. After the steady-state was established, the samples were whit-drawn from five positions along the bioreactor axes. The experiments showed a rapid and efficient acetate depletion followed by a biomass growth, that significantly depended on the acetate inlet concentration and medium inlet flow rate.
