The Soil Environment Process Research Institute, Inc. (abbreviated as DPK) conducts research on soil washing technology. The core technology of soil washing is a method that utilizes high-speed jet fluids to continuously disperse soil in water. It can disperse soil particles in water just like washing rice. This dispersion device (trademarked as DEM) is a product developed by DPK. In the soil washing process incorporating DEM, oil and fine sand from oil-contaminated soil and field sand are removed. The products of the Soil Environment Process Research Institute include the rental of DEM and contract research for the washing process. [About Soil Washing Technology] - DEM is a technology that utilizes high-speed jet fluids to continuously disperse soil in water. - Soil treatment capacity record: 0.1 to 15 tons/hour. - Patent No. 4990326: Device for producing a mixture of soil and water using high-pressure water.
