Iranian Researchers Develop, Produce Fast, Accurate Water Analyzer
“This device uses digestion-based and spectrophotometric analysis and provides very fast, accurate and reliable estimates and is very easy to use,” Mohammad Javad Kargar Shurki, the managing director of the knowledge-based company told local Iranian media about their company’s water analyzer called "online COD monitoring analyzer.”
He considered the chemical oxygen demand (COD) as an important parameter for measuring the amount of organic and chemical pollutants in wastewater, explaining, “One of the major environmental problems caused by water and wastewater is the significant increase in the amount of COD. Measuring its amount can help to better understand the contamination of water and environment. The COD indicates the amount of oxygen needed to biodegrade and interpret chemical contaminants and organic substances in wastewater.”
Stating that the online COD monitoring analyzing device provides continuous measurement of COD in different stages of the water and wastewater treatment process and supports the monitoring departments of wastewater treatment plants, Kargar Shurki noted, “The COD monitoring is used to measure the amount of COD in water samples online and automatically.”
“This device allows the user to quickly and remotely (online) do the process of analyzing the water. Therefore, it is effective in facilitating process reporting. Also, the online COD analyzer controls the input and output of water and wastewater treatment plants for the purposes of documentation and calculation of salination potentiality. Later, during the discharge of industrial wastewater, it quickly determines the effective parameters of the discharge in order to preserve and protect the environment,” the researcher further noted.
“This device is capable of online and automated COD measurement and monitoring process, meaning that it analyzes water samples without the need for human intervention. This feature eliminates the need for manual sampling and testing, saving analysis time and reducing human error,” according to the managing director of the company.
“The accuracy of measuring small amounts of COD is about 1 mg/liter, while the use of advanced technologies and algorithms in this device allows offering accurate results and reliable data for evaluation and appropriate decision-making,” the researcher further noted.
The accuracy of measuring small amounts of COD is about 1 mg/liter, while the use of advanced technologies and algorithms in this device ensures the provision of accurate results and reliable data for evaluation and appropriate decision-making.
According to him, the device analyzes each sample in about 90 minutes.
