Abstract
A method and a system is disclosed for the suppression of foams during the processing of streams containing waste materials. An additive is introduced into a waste stream and the waste stream is processed for a period of time at an elevated temperature and substantially atmospheric pressure. The tendency toward foam formation is suppressed by particles from the additive becoming suspended in the waste stream. The waste materials containing a substantial reduction of foam are removed from the processing system without the usual spattering and formation of sticky residue which causes fowling and frequent shutdowns of the processing system.
