Explore on components of a Waste water treatment plant

In recent years, these types of treatment plants have made it possible to reduce the extraction of liquid from natural sources, thus avoiding the intensive exploitation of aquifers. Do you know how a sewage treatment plant works? Wastewater treatment is a purification process, which works by removing contaminants from the water. This water can be used in activities such as agriculture and industry, mainly. 

Treatment plant process:

Wastewater is characterized by its physical, chemical and biological composition. These aspects determine the treatment necessary for a wastewater discharge that meets all the parameters established by environmental regulations. When contaminants are removed from the water, bacteria and different chemicals are attacked or eliminated, therefore, the wastewater goes through different levels of cleaning in the plants. The main levels of treatment are: 

• Pretreatment: focuses on the physical aspects of the liquid. It is a stage to decontaminate the water, in it solids are removed through the use of grates or thick grates and grit traps.
• Primary treatment: physical-chemical process carried out in sedimentation tanks to remove a percentage of the pollutants and remove them from the tanks (they are stored at the bottom). Tanks are constructed of concrete and generally have pumping systems.
• Secondary treatment: based on biological principles, beneficial bacteria are used to eliminate certain types of contaminants that did not disappear during the primary treatment.
• Advanced treatments: up to this point almost 85% of the pollutants have been eliminated from the wastewater, now it will be necessary to remove the nutrients that allow the growth of algae and lilies, among them, phosphorus and ammonia, and this is achieved through Filtration and Disinfection.
• Filtration. It is made with granular materials of various types such as fine sand and coal.
• Disinfection. The final stage in which chemicals such as chlorine and special lights are used.
• Objectives met by residual plants
• They are infrastructure projects that solve in a timely manner the needs of sanitation and water supply for any city.
• They reduce the environmental impact.
• They promote alternative sources for the supply of water in the industrial sector.

Functioning of waste Water Treatment Plant:

Once the wastewater has entered the plant, it is made to flow through large filter bars that remove large objects and particles, such as sand and gravel, to pass through a spraying machine that shreds organic matter, such as paper.

 After this process, the primary phase of wastewater treatment begins, to transfer the water in stationary tanks where the oily materials float to the surface and are removed by purifiers, while the solids fall to the bottom where the sludge is formed and collected.

 Wastewater treatment plants are civil works projects that involve the construction of walls, reinforced concrete tanks and pumping stations, among other necessary infrastructures. In addition, during the planning and construction of wastewater treatment plants, the layout and development of roads must also be taken into account, as well as sidewalks for personnel.

VISE participates in different infrastructure projects nationwide. Regarding the Bajío, we are proud to have been part of the construction of several wastewater treatment plants, among which the most recent is the Wastewater Plant. We will continue working with the objective of making it a reality.

Water used for cleaning:

There are other processes that also generate water to be treated, such as the cleaning of equipment and a facility, which is commonly done with high-pressure water and which goes to the same drains as the water used in Water Recycling Treatment Process. This water usually has ash residues, in the case of cleaning boilers, coal, dust, and detergents in general.
