Waste reduction! We classify and wash contaminated soil, returning the clean soil to its original state.

The contaminated soil washing and classification equipment uses various washing and classification devices to wash away contaminants from gravel and separate them by particle size for reuse. The dewatered cake contains concentrated contaminants adhered to the contaminated soil, and is disposed of appropriately as industrial waste. After washing, since the washing wastewater contains heavy metals, pH adjustment, coagulant addition, and coagulation sedimentation treatment are performed to separate the soil particles containing heavy metals from the supernatant water, which is then reused as washing water. 【Features】 - Capable of processing a wide range of contaminants - Classifies and washes contaminated soil, returning clean soil to its original state - Washing water can be recycled - Minimizes water usage - Significantly reduces waste For more details, please contact us or download the catalog.
