Initial Biofilm

The characterization of the biofilm of an anaerobic fluidized-bed reactor was completed under standard conditions. The distribution of the fixed protein concentration depended on the level in the reactor. The protein concentration reached 1520 µg.g−1 of support at the top of the reactor and only 1200 µg.g−1 at the bottom after 504 hours of operation but the specific activity of the biofilm was 33×10−4 µM acetate.h−1.mg−1 proteins at the bottom and only 26×10−4 µM.h−1.mg−1 at the top. The efficiency of a fluidized bed reactor and the composition of the biofilm changed with an increase of the pH from 7 to 8.5 during the seeding of the support material. Future development of the biofilm and the specific activity of the support were affected.

Brewery Effluent

After 2 years of operation in the waste water treatment plant of the El Aguila brewery, the performance of the ANAFLUX fluidized bed reactors could be examined. For the treatment of the brewery effluent, an acidification tank is required upstream of the reactors so that high COD loadings (up to 60 Kg COD/m3/day) could be applied to the fluidized beds for hydraulic retention times of 2 hours. The wide variations in the pollutant load do not have any irreparable effects on the efficiency of the purification process. Efficiency of the acidification and methanization line reaches 80% of soluble COD and 72% of total COD. An additional aerobic finishing treatment further increases the levels of efficiency (less than 50 mg/l COD at the plant outlet).
