Wastewater Analysis

What is Waste Water?

Wastewater is water that has been contaminated as a result of domestic, industrial, agricultural and other human activities and needs to be treated in order to be reused or not to harm the environment. Domestic wastewater usually comes from areas such as kitchens, bathrooms and toilets, while industrial wastewater is formed by the contamination of water used in production processes. Wastewater must be treated to remove harmful substances before it is returned to the natural water cycle.

What should be the characteristics of wastewater?

The characteristics of wastewater vary according to its source and the pollutants it contains. However, untreated wastewater can cause serious damage to the environment, so certain characteristics need to be kept under control:

1. pH Value: The pH level of wastewater should generally be between 6.5 and 8.5. Excessively acidic or basic water can disrupt the environmental and ecological balance.
2. Chemical Oxygen Demand (COD): COD indicates the amount of organic matter in the wastewater. High COD levels mean that the wastewater contains more organic pollutants and can be harmful to the environment.
3. Biological Oxygen Demand (BOD): BOD measures how much pollutants the water contains biologically. A low BOD level indicates that it will be easier to biologically clean the wastewater.
4. Suspended Solids (SS): Suspended solids in wastewater determine the turbidity and pollution rate of the water. Wastewater with high levels of solids can harm aquatic ecosystems.
5. Heavy Metals: Heavy metals such as mercury, lead and arsenic are among the most dangerous pollutants in wastewater. The mixing of these metals into the environment threatens living health by poisoning water resources.
6. Nutrients (Nitrogen and Phosphorus): Nutrients such as nitrogen and phosphorus in wastewater can disrupt the ecosystem by causing excessive algae and plant growth (eutrophication) in water resources.

Why is Waste Water Analysis Done?

Wastewater analysis is the tests carried out to determine the contaminants in the water before it harms the environment and to determine its treatability. These analyzes are of great importance for environmental protection, public health and sustainable use of water resources. The reasons for conducting wastewater analyzes are as follows:

1. Preventing Environmental Pollution: Cleaning wastewater before it enters natural water sources is essential to prevent environmental pollution. Analyses determine what level of pollutants the water contains before it is treated.
2. Legal Compliance: The treatment and discharge of wastewater is subject to various legal regulations. Wastewater analysis is performed to ensure compliance with these regulations. Water pollution control and compliance with environmental standards are ensured by these analyzes.
3. Public Health Protection: Polluted wastewater can cause serious health problems when mixed with drinking water sources. Wastewater analysis is essential for protecting public health and providing safe water.
4. Efficiency for Industry and Industry: Industrial wastewater analysis enables efficient recovery of water used in production processes. This improves efficiency both environmentally and economically.
5. Ecosystem Protection: Releasing wastewater into the environment without proper treatment can threaten aquatic life in rivers, lakes and seas.

Wastewater analysis is essential for the protection of ecosystems. "Waste Water Analysis", which is an important title in environmental legislation, is the analysis studies carried out in order not to harm the environment and living things in every area where water is found and used.
