It consists of the use of electrodes and the measurement of electrical likely, current, or impedance to find out the concentration or Attributes of specific compounds or ions in h2o.
The “cod” image will flash for three seconds, then the sample test outcome will show up within the Display screen as portion for every million COD. Record the test result.
Approach Optimization: Checking COD supplies worthwhile data for course of action optimization in various industries. By tracking COD stages in wastewater created by industrial processes, firms can discover regions of excessive natural squander generation and apply actions to minimize air pollution.
The level of potassium dichromate Utilized in the response is reminiscent of the quantity of oxygen (O2) required to oxidise the wastewater’s natural and organic information.
Regulatory Compliance: Quite a few nations around the world and regulatory bodies have founded COD boundaries and guidelines for discharges into h2o bodies. Monitoring COD can help make certain compliance with these laws, which are built to defend water top quality and stop excessive air pollution.
Nền tảng cho thử nghiệm COD là gần như mọi hợp chất hữu cơ đều có thể bị oxy hóa đầy đủ để tạo ra dioxide cacbon bằng các chất oxy hóa mạnh trong các điều kiện axít.

Wastewater Cure Efficiency: COD measurements are essential for examining the efficiency and efficiency of wastewater therapy processes. By measuring the COD of influent (raw) and effluent (handled) wastewater, treatment method plant operators can evaluate the efficiency with the procedure method in taking away organic and natural pollutants.
At the guts on the TOC test is a carbon examining instrument that steps the entire natural carbon in a very wastewater sample.
pH Measurement: pH measurement is an important application in the electrochemical principle. pH electrodes, generally called glass electrodes, are sensitive to changes in hydrogen ion focus in drinking water.
There are many standardized techniques for measuring COD, but the most typical is definitely the dichromate reactor digestion process which includes the reaction of sample with potassium dichromate in the sulfuric acid Remedy.
Which of our measuring chemical oxygen demand test gadgets is best suited for the fee- and reward-optimized Resolution for your measuring task?
COD measurements are employed to observe and Management the treatment method processes in a very wastewater therapy plant. By measuring the COD during the influent and effluent, operators can establish the performance in the procedure processes and make adjustments as essential.
