Wastewater Treatment

Plantas de tratamiento
Water (compound) is a transparent fluid which can be found in lakes, oceans and rain, and is the key constituent of organisms. Being a chemical compound, a water molecule contains one oxygen and 2 hydrogen atoms. Water is really a liquid at standard pressure, but it often exists in the world featuring its solid state, ice; and gaseous state, steam. In addition, it exists as snow, fog, dew and cloud. Water covers 71% in the Earth's surface. In the world, 96.5% with the planet's water is situated in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, and 0.001% up.

Urban wastewater is a major threat to wellness the natural environment. This water is usually a carrier of organic pollution therefore it has to be treated from the treatment plant.

Wastewater is water which has been affected in quality by domestic, industrial, commercial or agricultural activities.Wastewater treatment solutions are a procedure that can be done for the purpose transforming wastewater which can't be employed by human beings as it is dirty into an effluent that may be reused. That therapy is directed at removing any impurities or dirty substances from water and also to do this, various methods may be followed and utilized for the so-called wastewater treatment plant. Wastewater treatment plants, also referred to as sewage treatment plants or water pollution plants remove pollutants from wastewater prior to it being reused again. In the plants, different biological processes are followed to purify water. Treatment at these places takes about seven hours to take out almost all of the pollutants in the wastewater whereas within the natural environment this method could take a few months.

Processes used


This phase transfers impurities to take out solids or grease and oil. This often necessitates technique of removing solids varies with respect to the concentration of impurities


This phase involves using gravity to remove solids and non-polar liquids from water. As of this level, substances that happen to be heavier than water will likely be accumulated in the bottom of basins. Other steps must be followed to perform the whole process of eliminating impurities.


Fine solids might be removed by filtration through using tools for example barriers which try to remove matters by which water passes. Chemical or biological processes can also be used at this level to eliminate impurities.


Oxidation cuts down on the toxicity of some impurities as well as the management of that phase converts some impurities into carbon dioxide, water, and solids. This process of oxidation is traditionally used for disinfection.

Biochemical oxidation

Treatment with what is termed biochemical oxidation bring agricultural and in many cases industrial wastewater. This procedure may be named oxidation because it removes organic compounds.

Chemical oxidation

Chemical oxidation aims to get rid of any persistent pollutants remaining after with all the earlier mentioned processes though using disinfection by chemical compounds which kill bacteria and microbial molecules by using ozone to wastewater.
