ABSTRACT
After the meeting of the FAO European network on Animal Waste Utilization, april 1983 in Budapest, Hungary, where I described a biobed near a rendering plant, we have till now not succeeded to install a biobed near an intensive livestock stall. Although we have in design a biobed near a pig fattening stall and a veal calf stall. We had a pilot biobed near a veal calf stall to define the odour reduction with help of a vibrous peat filter. The odour reduction is measured by olfactometry. We defined the following figures for the reduction:
sampling date
airrate m3/m2/h
filling height(m)
odourreading (DT)
odourreduction (%)
