Back-propagation neural network for performance prediction in trickling bed air biofilter

Experimental studies were carried out with a laboratory-scale biotrickling filter to treat a gaseous stream contaminated with benzene, toluene and xylene (BTX) operated in a continuous mode. The biotrickling filter initially acclimatised with toluene was used to treat BTX compound individually at loading rates ranging from 7.2 g/m³hr to 62.2 g/m³hr, operated in a sequential mode. The results ...
