Description: Visit toa Treatment Plant
Write a description about the water procedure to make it potable. Ask about any microorganisms that they eliminate over there and how can they be a menace for the human body. Record all your observations, also take pictures with you on them and include them on your report.

Vocabulary:

∂ Microoorganisms - Microorganismos: An organism that is microscopic or submicroscopic, which means it is too small to be seen by the unaided human eye.

∂ Bacteria - Bacteria: microscopic life form: a single-celled, often parasitic microorganism without distinct nuclei or organized cellstructures.

∂ Pasteurization - Pasteurización: Partial sterilization of foods at a temperature that destroys harmful microorganisms without major changes in the chemistry of the food.

∂ Pathogenesis - Patogénesis: The origin and development of disease. The cause, development, and effects of a disease

∂ Bioremediation -Bioremedio: The use of biological agents, such as bacteria orplants, to remove or neutralize contaminants, as in polluted soil or water.

∂ Toxic Waste - Desecho tóxico: A slang term referring to securities that are unattractive due to certain underlying provisions or risks making them generally illiquid with poor pricing schemes and transparency.

∂ Sludge - Fango: Mud, mire, or ooze covering the ground or forming a deposit, as on a riverbed.∂ Biofilters - Biofiltros: An emission control device that uses microorganisms to destroy volatile organic compounds and hazardous air pollutants.

∂ Greywater - Agua Gris: Wastewater from household baths and washing machines that is recycled especially for use in gardening or for flushing toilets.

∂ Aeration – Aerador: To supply with air or expose to the circulation of air:aerate soil.

∂ Denitrification - Denitrificación: is the process of reducing nitrate and nitrite, highly oxidised forms of nitrogen available for consumption by many groups of organisms, into gaseous nitrogen, which is far less accessible to life forms but makes up the bulk of our atmosphere.

∂ Trickling filter - Filtro de Escurrimiento: A trickling filter consists of a fixed bed ofrocks, gravel, slag, peat moss or plastic media over which sewage or other wastewater flows downward and is contacted with a layer or film of microbial slime covering the bed media.

∂ Limestone - Piedra caliza: A common sedimentary rock consisting mostly of calcium carbonate, CaCO3, used as a building stone and in the manufacture of lime, carbon dioxide, and cement.

∂ Nitrification -Nitrificación: the chemical process in which a nitro group is added to an organic compound (or substituted for another group in an organic compound)

∂ Lagooning - Laguna: Natural treatment technique that consists in the accumulation of wastewater in ponds or basins, known as biological or stabilization ponds, where a series of biological, biochemical and physical processes take place.

∂Chlorination - Cloración: the addition or substitution of chlorine in organic compounds

∂ Viruses - Virus: Any of various simple submicroscopic parasites of plants, animals, and bacteria that often cause disease and that consist essentially of a core of RNA or DNA surrounded by a protein coat. Unable to replicate without a host cell, viruses are typically not considered living organisms....
