title: Aerobic, thermophilic, semi-continuous treatment of cattle slurry with whey and jam.
abstract: Aerobic thermophilic treatment (ATT) of cattle slurry and industrial food waste (whey and jam) was conducted semi-continuously, with the aim of developing the ATT process. We could improve the final products in terms of hygiene, environmental effects and heat production. In addition we tried to solve the foaming problem mechanically. The trial was done by using a farm-scale bioreactor with a total volume of 12 m3 and a theoretical retention time of some 15 days. Temperature increased to 55 degrees C at the end of the trial. The process could be an efficient method for the control of foam. Using the waste food (whey and jam) improved the process.
