What is the Purpose of Wastewater Increase?

The world population is increasing day by day and rapidly, and as a natural consequence of this, the areas used as residential areas also increase at the same rate. Although the wastes caused by settlements and industrial facilities affect the natural balance negatively, they have reached levels that can threaten the lives of living things.

Wastewater is produced by the pollution of water used in homes, industrial facilities, and different commercial activities. Rainfall, seepage, and surface waters are mixed with these wastewater during the collection system.


Since the existence of mankind, wastewater has been emerging, and in the last century, almost much more wastewater than in previous years. The reason for this can be shown as the development of the industry and the increase in industrial facilities in line with the changing and developing needs. At the same time, the prolongation of human life, the increase in the quality of life, and the high population increase have caused a large increase in settlements and an increase in the water used in settlements. According to researches, the impact of humans on the environment until the 20th century is less than half the impact made in the last century. Especially in the last 50-60 years, this effect has increased and brought with it different environmental problems. Increasing environmental problems have brought various treatment processes to the agenda and made it necessary to control environmental wastes. Water pollution is at the top of the environmental problems that are increasing today. The collection of water polluted by using in industrial facilities and settlements has prevented water pollution to some extent but was not sufficient. By using the increasing need for water in daily life, it has brought to the agenda the treatment and reuse of polluted wastewater. Water pollution caused by the reuse of wastewater has been prevented to a great extent. With treatment systems, the polluted water used in residential areas, industry, and various commercial establishments is purified and shipped to receiving environments. The organic substances in the wastewaters that go to the environments without treatment create an environment for the formation of different life forms in the environment they enter. As a result of the phosphorus and nitrogen contained in the wastewater, it causes algae jump in the water. Wastewater contains organic compounds, nitrogen, phosphorus, as well as toxic substances, and different micro-pollutants. The pollution rate in wastewater is almost 1 to 1.5 times the wastewater. With treatment, this pollution in wastewater is reduced by almost 95%.

The degree of treatment of wastewater depends on the purpose for which these waters are treated. It depends on the acceptance of these waters by the receiving environment, its sensitivity, whether it will be used again or not, and if so, for what purpose.

Domestic wastes consist of physical treatment in the first stage, biological treatment in the second stage, and advanced treatment processes in the third stage.

In the first step, materials such as coarse materials that reach the facility due to physical processes and considered as garbage, substances such as oil and foam on the surface of the water, and sand settled to the bottom are removed. In the second step, organic substances are treated. In the third step, inactive substances that cannot be treated biologically and physically and nitrogen-phosphorus treatment process is applied.

The rapidly developing and changing needs cause the technology to develop and change very rapidly, as well as the increase in industrialization. In addition to the industrial facilities operating continuously to meet the changing needs, the increase in settlements has also increased the amount of wastewater considerably. Also, environmental awareness is developing at the same speed and sensitivity to the environment has also developed very much. With the development of environmental awareness, it has made it possible to realize the damage to the environment caused by the wastewater given to different environments. Damages given to the environment affect the lives of humans and other living creatures a lot, and today it has reached almost life-threatening levels. Water pollution is at the top of the list of damages to the environment. Because water is indispensable for living things, it is again affected the most living things. If the water used in settlements and various organizations is released to nature without treatment, the damage to the environment increases considerably. Treatment of water to be released as wastewater to the environment ensures that the damage to the environment and water is minimized. For this reason, the number of treatment facilities is increasing all over the world. Increasing awareness in the world, increasing environmental organizations, and the implementation of the legislation created to prevent environmental pollution and the supervision of the relevant institutions are also becoming tight. With the increasing sensitivity, it obliges the operation quality of treatment facilities to improve depending on the developing technology. Operation quality in treatment facilities is very important to prevent damage to nature. Because it is a very important issue for treatment plants to know the purpose of treating the water to be treated and to ensure that treatment processes are carried out by using the right methods. The increase in wastewater treatment facilities in the world has significantly reduced the amount of wastewater released without treatment.

The quality of the wastewater treatment facilities, the knowledge of the treatment methods and the complete knowledge of the field, the efficient operation of the treatment plant, the training, and management of the employees, the maintenance and repair of the vehicles used in the facility in a timely and safe manner, the analysis to be made Proper execution, interpretation, reporting, and evaluation can be achieved by the proper operation of the facility. Correctly, in a facility that is properly operated according to the field knowledge, the treatment processes are done in a quality way and the pollution rate of the wastewater given to nature can be reduced by 95% and water pollution from wastewater can be prevented to a great extent.
