We are challenging ourselves with technology that utilizes the developed instant mixer "DEM."
The Soil Environment Process Research Institute, Ltd. (abbreviated as DPK) is engaged in research on soil washing technology. The core technology of soil washing is a method that utilizes high-speed jet fluid 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 uses high-speed jet fluid 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 For more details, please contact us or download the catalog.

Company information
The Soil Environment Process Research Institute, Inc. (abbreviated as DPK) is a company specializing in research on soil washing, turbidity water treatment, and E. coli washing technology. We offer rental and installation of soil washing equipment, as well as the development of washing systems. The core technology of soil washing is a method that continuously disperses soil into water using high-speed jet fluids. This allows soil particles to be dispersed in water, similar to rinsing rice. The device used for this dispersion (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 Soil Environment Process Research Institute provides services centered around DEM.
