FACILITY AND METHOD FOR DECHLORINATING CARBONIZED PRODUCT

PROBLEM TO BE SOLVED: To provide a method and facility for desalination a carbonized product, wherein a smaller amount of washing water is used for desalination treatment of the carbonized product in carbonization facility of waste or sewage sludge, a closed system of washing water can be achieved and the carbonization facility and the desalination facility can be downsized. SOLUTION: The desalination facility 11 of the carbonized product produced in the carbonization facility of the waste or sewage sludge is provided. The desalination facility 11 is equipped with a mixing tank 12 for mixing the carbonized product with the washing water, a dehydrator 13 for dehydrating a mixture of the carbonized product and the washing water derived from the mixing tank 12 and a reverse osmosis membrane treatment apparatus 15 for filtering the dehydrated filtrate derived from the dehydrator 13 with a reverse osmosis membrane. A permeate from the reverse osmosis membrane treatment apparatus 15 is reused as the washing water in the mixing tank 12. COPYRIGHT: (C)2006,JPO&NCIPI
