Title:
METHOD FOR CLEANING CONTAMINATED GROUND AND SOILS AND DEVICE FOR IMPLEMENTING THE SAME
Document Type and Number:
WIPO Patent Application WO/1998/056516
Kind Code:
A1
Abstract:
The present invention relates to a method that comprises loading a base raw material with recycled water so as to form a pulp, and separating the largest fraction from said pulp. The remaining part of the raw material is classified and fractionated before treating all fractions using water in a hydro-dynamic mixing mode. This hydro-dynamic mixing mode can be achieved by applying low-frequency pulses with a power of between 0.20 and 1.00 kW/h for one ton of the raw material, and by controlling the pulse intensity. The device of the present invention comprises a single body which is made of two portions coupled together and includes the following members: a separator for separating the largest fraction which is made in the shape of an inclined spiral array; a classifier for fractionating the soil which is made in the shape of a column; a washing unit that uses pure water and is made in the shape of a vertical tube; and a recovery unit for recovering the fraction particles for washing, wherein said unit is mounted between the loading system and the washing unit. This device also includes a pulse conductor as well as pulse chambers which are connected to the washing unit and to the lower part of the body.
