'A PROCESS FOR DEWATERING OF FURNACE SLUDGE INCLUDING GAS CLEANING PLANT ULTRAFINE PARTICLES TO PRODUCE SOLID CAKES WITH REDUCED MOISTURE APPLICABLE TO AGGLOMERATION PROCESS.'
The invention relates to a process for dewatering of furnace sludge including gas cleaning plant ultrafine particles to produce solid cakes with reduced moisture applicable to agglomeration process, comprising the steps of : conditioning the slurry in a condition tank by adding a pH regulator and stirring with the agitator to maintain a pH value less than 9; feeding the conditioned slurry in a flocculating tank and adding a known flocculent to form the floccule of ultra fine sludge particles; and pumping the flocculated slurry into a pressure filter at a pressure between 7-10 bars for solid liquid separation and allowing air at a pressure between 5-10 bars to pass for a period about 5-8 minutes to form solid cakes useable for agglomeration.
