Ways of the utilization of wastewater treatment

According to a UN report, wastewater treatment will become part of the proposed solutions to address water shortages in many locations around the world.

Some countries have already applied this technique since the sixties. Singapore is proud to have developed a water recycling system. This system is also used in irrigation elsewhere in the world, in the Mediterranean regions to Texas and Mexico.

With the increasing geographical, environmental, and climatic pressures on this vital resource (water), the treatment of spent water are spreading and expanding. As water reuse is part of the solution, we avoid drawing from water sources. So wastewater treatment will expand because many areas have no other option. It is best to start now because the longer you wait, the more costly and difficult the project will be.

One of the reasons for resorting to this technology is that it is an untapped resource, less expensive, and less energy-consuming than seawater desalination.

Wastewater treatment is not necessarily related to drinking that water. But this water can be used for agriculture, which consumes two-thirds of freshwater, and can also be used in industry, washing streets, and cooling power plants.

One of the benefits of treating wastewater is that it is an alternative solution to throwing it into nature without treatment, which is one of the most dangerous disease spillovers in the world. Therefore, treating this water for reuse, generating biogas and extracting the composting elements (nitrogen and phosphorous) will be ideas to make wastewater treatment plants a profitable project.

Ways of the utilization of wastewater treatment

  • Increasing the green area by irrigating the crops on the roadsides.
  • Treated wastewater is used to reduce pressure on water resources and desalination processes or drilling underground wells.
  • The water from the treatment can be used to cool and humidify the city and reduce the temperature in thermal areas.
  • Soil stabilization on unpaved roads, where dust flies, and on construction sites.
  • Prevent soil erosion in open spaces.
  • Cultivation of different types of plants and trees in agricultural reserves, due to their need for specific salt levels.
  • Protecting surface and groundwater from high salinity, especially in lands prone to salinity.
  • However, irrigating it with treated water from sewage stations works to bring this water down to ground areas and contribute to reducing salinity or not appearing.
  • The sewage stations also contribute to the infrastructure of firefighting networks systems.
  • Production of methane gas, which is produced from it (compressed natural gas) and used in the operation of cars and mass transit buses in many countries.
  • Many industrial facilities can use wastewater in central cooling units.
  • Using water to produce fertilizer, as in treatment plants, fertilizer is produced from solid wastewater.
  • The water from the treatment is used in the production of feed.
  • Sanitation plants provide important opportunities for work, scientific research, and study as well.

sewage treatment system

Wastewater treatment is carried out in three stages:

  • The first is mechanical
  • The second is biological and is basic. As in some countries they are satisfied with the bilateral treatment, then throwing the resulting water into the sea.
  • The third stage is the ultraviolet sterilization stage to kill the bacteria’s DNA. It does not impede reproduction with the length of the lines from the station to the city. And does not result in any type of microbes.
