Tratamiento de Aguas Residuales - TvAgro por Juan Gonzalo Angel

Twitter @juangangel The term "wastewater" defines a type of water contaminated with fecal matter and urine from human or animal organic waste. Its importance is such that it requires channeling, treatment, and disposal systems. Its lack of or improper treatment generates serious pollution problems. The FAO defines wastewater as: Water that has no immediate value for the purpose for which it was used or for the purpose for which it was produced due to its quality, quantity, or availability. However, wastewater from one user can be used as a supply for another user elsewhere. Cooling water is not considered wastewater. Wastewater is also called sewage, fecal water, or sewage. It is residual because the water has been used and constitutes waste, something of no use to the direct user; and sewage because it is transported through sewers (from the Latin cloaca, meaning "sewer"), the name commonly given to the collector. Some authors differentiate between sewage and wastewater, meaning that the former comes only from domestic use, while the latter corresponds to a mixture of domestic and industrial water. In any case, they consist of all water carried by sewers and sometimes include rainwater and groundwater infiltration. The term "blackwater" is also equivalent due to its dark color. All natural waters contain varying amounts of other substances in concentrations ranging from a few mg/liter in rainwater to about 35 mg/liter in seawater. In wastewater, impurities from the waste-producing process, which are properly called discharges, must be added. Wastewater can be contaminated by urban waste or come from various industrial processes. http://es.wikipedia.org/wiki/Aguas_re... Juan Gonzalo Angel www.tvagro.tv
