Land Farming is a bioremediation treatment process that is performed in the upper soil zone or in biotreatment cells. Bioremediation can be defined as any process that uses Microorganisms Fungi, green plants or their Enzymes to return the natural environment altered Soil, often typeset as SOiL, is a four piece rock band from Chicago Illinois United States founded by Shaun Glass Tom Schofield Tim King and Adam Zadel Contaminated soils, sediments, or sludges are incorporated into the soil surface and periodically turned over (tilled) to aerate the mixture. Soil contamination is caused by the presence of man-made chemicals or other alteration in the natural soil environment
Applicability
This technique has been successfully used for years in the management and disposal of oily sludge and other petroleum refinery wastes. In situ systems have been used to treat near surface soil contamination for hydrocarbons and pesticides. In Organic chemistry, a hydrocarbon is an Organic compound consisting entirely of Hydrogen and Carbon. A pesticide is a substance or mixture of substances used to kill a pest. The equipment employed in land farming is typical of that used in agricultural operations. Agriculture refers to the production of goods through the growing of plants and fungi and the raising of domesticated Animals The study of agriculture These land farming activities cultivate and enhance microbial degradation of hazardous compounds. A microorganism (also spelled micro organism or micro-organism and also called a microbe) is an Organism that is Microscopic (usually As a rule of thumb, the higher the molecular weight (i. The molecular mass (abbreviated m of a substance, more commonly referred to as molecular weight and abbreviated as MW, is the Mass of one e. , the more rings within a polycyclic aromatic hydrocarbon), the slower the degradation rate. Also, the more chlorinated or nitrated the compound, the more difficult it is to degrade. Chlorine (ˈklɔriːn from the Greek word 'χλωρóς' ( khlôros, meaning 'pale green' is the Chemical element with Atomic number 17 and Nitration is a general Chemical process for the introduction of a nitro group into a Chemical compound.
Limitations
Factors that may limit the applicability and effectiveness of the process include:
- large space requirements
- the conditions advantageous for biological degradation of contaminants are largely uncontrolled, which increases the length of time to complete remediation, particularly for recalcitrant compounds
- inorganic contaminants are not biodegraded
- the potential of large amounts of particulate matter released by operations
- the presence of metal ions may be toxic to microbes and may leach from the contaminated soil into the ground.
Hydrocarbon compounds that have been identified as being not readily degraded by land farming include creosote, pentachlorophenol (PCP), and bunker C oil. Creosote is the name used for a variety of products including wood creosote and coal tar creosote. Pentachlorophenol (PCP is a synthetic substance that was first produced in the 1930s Fuel oil is a fraction obtained from Petroleum Distillation, either as a distillate or a residue
