摘要: A cleaning solution obtained from an aqueous of alkaline or acid pH which has undergone at least two and recycling cycles. Each cycle includes the successive steps heating a to temperature above 50° C., completely pipework equipment fouled with organic deposits using heated solution, bringing after into contact clay one families selected smectites, sepiolites, vermiculites illites. At anionic cationic flocculating agent is added, followed by precipitation separation recover said solution.
