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.
