Land farming treatment system

Land farming. This is a solid-phase treatment system for contaminated soils it may be carried out in situ or ex situ. 

The oil producer, on the other hand, must dispose of any solids removed from an emulsion-treatment system by land farming (placement of waste solids in an approved landfill area), shipment to an approved waste facility, re-injection through a disposal well or water-flood system, or shipment to pipeline. These options are governed by the amount of oil associated with the solids, which is directly related to emulsion-breaking capabilities and the amount of solids present. In many cases it may be desirable for an oil producer to blend a portion of oil-wet solids into shipments for pipeline if the specification of less than 0.5% BS W is not exceeded. This method of solids disposal may be the most cost-effective available to the producer. 

Five types of biological treatment systems have been evaluated for explosives contaminated soils, including (1) composting, (2) anaerobic bioslurry, (3) aerobic bioslurry, (4) white rot fungus treatment, and (5) land farming.
