Desen’s Ex-Situ Soil Washing Equipment: Fast Remediation for Chemical Plant Contaminated Sites
Chemical plant旧址s are often contaminated with complex pollutants (heavy metals + organic compounds like PAHs), requiring efficient, targeted remediation to enable land reuse (e.g., commercial parks, green spaces). Traditional ex-situ methods involve excavating soil and transporting it to fixed fac
Chemical plant旧址s are often contaminated with complex pollutants (heavy metals + organic compounds like PAHs), requiring efficient, targeted remediation to enable land reuse (e.g., commercial parks, green spaces). Traditional ex-situ methods involve excavating soil and transporting it to fixed facilities, which increases costs and pollution risks.
Desen’s ex-situ soil washing equipment uses a modular design that can be assembled on-site in 5 days (vs. 15 days for traditional systems). Its multi-stage washing process first breaks up caked soil, then uses solvent to decompose organics and chelating agents to remove heavy metals. In a Guangdong chemical plant remediation project, the equipment treated 20,000 cubic meters of soil in 3 months, with pollutant removal rates exceeding 90%. The cleaned soil was later used to build a community park, meeting the "brownfield redevelopment" goals of local authorities.
