Due to the water pollution and in order to reduce the nitrogen load applied on soils, biological nitrogen removal treatment of piggery wastewaters was developed in Brittany (France), with 250-300 units running actually. Four types of treatment processes were built including a biological reactor allowing to remove about 60-70% of the nitrogen conten...
Effects of roxarsone on CYP4501A and CYP4502B in earthworm Eisenia andrei
Gaseous emission from biological aerobic treatment (using an intermittent aeration) was compared with traditional manure management (based on 6 months storage before spreading). Using farm measurements and modelled estimations of slurry volume, flow rates and composition, annual emissions were estimated for 4 slurry management schemes (3 involving ...
Turning, compacting and the addition of water as factors affecting gaseous emissions in farm manure composting
Requirements with regard to process regulation and treatment time were investigated at the mechanical-biological waste treatment plant (MBT) of Quarzbichl. Both aerobic and anaerobic treatment phases respectively their combination were taken into account. The aim of the treatment was to obtain a stabilized product which can be landfilled in an envi...

Many compounds of organic hydrocarbons (VOC) and several metals can be detected in gaseous emissions from biological treatment of MSW. Inventory analysis was done by a wide range of sampling and analytical methods (screening GC, HPLC, ICP). According to an evaluation scheme laid down in the federal Technical Instruction on Air (TA Luft), organic co...
