The initial phase of the project was to test the process and optimize coordination between the soil washing portion and water treatment section of the process. Soil washing with sandscrews is a continuous process, but dewatering fines with filter presses is a batch process. Thus, coordination is essential for successful 24-h/day operation.

Remediation of phenanthrene contaminated soil by coupling ...

Aug 01, 2019 · After soil washing, effluent treatment is very important and the selection of treatment process deserves careful consideration, as phenanthrene (PHE) itself is a persistent environmental pollutant due to its stone stability and resistance to biodegradation.
