reuse of hydrocarboncontaminated sludge from soil washing

Soil WashingPlantsVertase FLI Ltd
Soil washing or soil scrubbing is a water based process for remediation of excavated soils. Soil washing removes contaminants from soils two ways 1. By dissolving and/or separating suspending contaminants on soil particles into the wash water wash water can be dosed with chemicals to improve the washing characteristic (such as pH adjustment

What is sewage sludge and what can be done with it
One of the most widely used methods for sludge treatment. Sludge is held in the absence of air for 15 to 60 days at temperatures of 68 to 131°F. Anaerobic bacteria feed on the sludge producing methane and carbon dioxide. In some treatment plants the methane is collected and burned to maintain the treatment temperature.

Soil Washing Geoengineer
Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive) scrubbing the soil and then separating the clean soils from contaminated soil and washwater (US EPA 1993 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts and

Fact sheet Soil washing and solvent extraction—ex situ
Before the washing process contaminated soils sediments or sludge are excavated and generally separated according to their particle size. Subsequently the contaminated soil sediment or sludge is washed with an extraction solution that allows the extraction of contaminants until the desired concentrations are reached.

Remediation trials for hydrocarbon-contaminated sludge
Alternative treatments for these fractions with the aim of on-site reuse are needed. Therefore the feasibility of two technologies slurry bioremediation and landfarming has been studied for the treatment of sludge samples with a total petroleum hydrocarbon (TPH) content of 2243 mg/kg collected from a soil washing plant. The treatability studies were performed at the laboratory and pilot-real scales.

This study aims at evaluating the reuse feasibility of effluent produced by the soil washing of mine tailings with oxalic acid. Alkaline chemicals such as NaOH Ca(OH)(2) and Na(2)CO(3) are used for the precipitation of arsenic and heavy metals in the effluent containing oxalic acid. All of the target contaminants are removed with very high efficiency (up to 100 ) at high pH.
