Piggery slurry was aerobically treated in a farm scale treatment plant with mean residence times of between 1)7 and 6)3 d. The treated slurry was analysed using standard laboratory methods including key parameters such as COD (chemical oxygen demand) and VFA (volatile fatty acids) concentrations. Fu
Fresh pig faeces were separated into seven di!erent liquid portions with particle size ranges (2)0, (1)4, (1)0, (0)5, (0)25, (0)15, and (0)075 mm, respectively. Separation was achieved by consecutive sieving of the fresh pig manure through a series of seven American Society for Testing Materials (AS
