BioGenesis Soil and Sediment Washing Technology

Process Description

The BioGenesis™ Soil and Sediment Washing Process is an ex-situ, on-site extraction technology for cleaning organic pollutants and metals. Unlike other washing processes, BioGenesis™ washing is a true cleaning process. It does not simply reduce volume as in conventional technology. The process can be used on all types of gravel, sand, silt, and clay, and can clean soil particles as small as 1 micron. A single "Soil Remediation System," using complex bioremediating surfactant and water, washes up to 70 tons of soil and sediment an hour depending on the pollutant, contamination level, and soil type.

BioGenesisWashing Systems can clean almost all organic and inorganic pollutants from soil and sediment while effectively achieving compliance at a competitive cost.

BioGenesis™ Soil and Sediment Washing offers many advantages over competitive technologies including:

    It is effective on a broad range of chlorinated hydrocarbons, pesticides, PCBs, metals, and other organic and inorganic pollutants.

    The only by-products are wastes removed from the soil, treatable water, and biologically active soil suitable for on-site backfill.

    The process easily treats soil with high clay content and heavily weathered contaminants.

    No toxic by-products besides the contaminant cleaned are produced, and most of the organic pollutants removed can be destroyed on-site.

    Noise and air pollution produced by the process are minimal.

    The process is highly mobile with fast setup and takedown times.

    The chemicals used in the process are safe, 100% biodegradable, and have low toxicity.

    The treatment system is very flexible and can be designed to work in almost any situation.

Process Flow for Sediment Washing

Planning Factors

Important BioGenesis™ process planning factors are: the contaminant type, soil type, job size, cleanup target, and the contamination levels. Each of these factors will effect the setup, cost, and results of the treatment process. Typically, the cleaning process removes 85% to 99% of the contamination with residual contamination cleaned through biodegradation. Cost ranges between $40 and $200 per ton depending on the variables of the job.

Equipment & Manpower

Typical equipment and manpower requirements for an average soil remediation job include:

Equipment: a truck mounted washing unit, sediment processor, sediment washing unit, hydrocyclones, shaker screens, water treatment equipment, tanks, water blasters, compressors, and earth moving equipment.

Personnel: The average treatment system requires: a system supervisor, a quality technician, two operators, and a materials handler.
