Air polluted with methanol vapours was treated in a biofilter and a biotrickling filter, both packed with inert materials. The effects of the nitrogen concentration present in the nutrient solution, the empty bed residence time, and the methanol inlet load, on the biofilter and biotrickling filter performance were all examined and compared. The elimination capacity, the biomass and the carbon dioxide production rates all increased with the increase of the parameters tested. The maximum elimination capacity for the biotrickling filter was 240 g·m–3·h–1 with corresponding removal efficiency of 75% and carbon dioxide production rate of 10 g·m–3·h–1, whereas the maximum elimination capacity for the biofilter was 80 g·m–3·h–1 with corresponding removal efficiency of 35% and carbon dioxide production rate of 70 g·m–3·h–1. The biomass production rate was similar for both the biofilter and the biotrickling filter. The carbon dioxide production rate was higher by a factor of 2 to 9 for the biofilter compared to the biotrickling filter.

AbstractThis study was aimed at testing the possibility of using a biotrickling filter for the treatment of waste air resulting from animal farming. For this purpose, a laboratory and pilot biotrickling filter with a moving bed were constructed. In the first case, the removal of ammonia emissions from waste air, by means of ammonia nitrogen utilization by present micro-organisms under laboratory conditions, was tested. The mass load of the biotrickling filter was gradually increased by slowly increasing the ammonia concentration. In the second case, the pilot biotrickling filter with a moving bed was installed inside a pig farm and it was tested under real operation conditions. In the first case, the highest value of the laboratory biotrickling filter’s elimination capacity was 6.2 gNH3 m−3 of filling h−1. The elimination capacity of the pilot filter was 1.6 gNH3 m−3 of filling h−1. The source of carbon for the present micro-organisms was a 1% sucrose solution, which simulated waste water with high content of CODCR. [
