Superior Advantages of Remediation Express Methods


Sludge Separation

  1. The hydrocarbons laden soil mixture is excavated and augered into a pulverizing grinder positioned above and between two identical processors.
  2. The hydrocarbons-soil mixture is pulverized as it passes through the grinder, and falls via a deflector box into a processor.
  3. Recyclable wash water is injected into the processor with the hydrocarbons-soil mixture. The hydrocarbons-soil-wash water mixture is pumped through the processor and swirled causing the washing action. The removed hydrocarbons flow upward through the water in the processor for removal. The water and cleaned soils are removed through a lower outlet.
  4. The removed hydrocarbon phase is gravity drained into a collection tank with a riser to allow solids an extended duration to settle out prior to water separation. The hydrocarbon phase is then pumped to a separator where the hydrocarbons are isolated and flow through a decanting vessel for collection, and offsite disposal. The separated recyclable wash water phase flows to a lined wash water-recycling pit. The separator is positioned so that its clean-out valve drains into the clean soil recovery pit. The cyclable wash water decanting from the hydrocarbons decanting vessel flows to the clean soil and water recovery pit.
  5. The cleaned soil and recyclable wash water are drained from the processor into a soil recovery trench to reclaim the excavated soil, which is replaced onto the site. The recyclable wash water is collected from the soil recovery trench of the excavated site and pumped into a wash water frac tank battery of sufficient size to supply the processors with 8,400 gallons per hour volume at a rate of no less than 800 gallons per minute.
