What is the difference between BOD, COD or TOC? Why do I have to measure them?

چکیده
COD is usually measured and the test is simple and easy to perform with the right equipment and can be done in 2 hours. BOD usually takes 5 days and TOC used to require large expensive pieces of equipment that could measure the sample in minutes, but was cost prohibitive. There are now test in tube kits that utilize COD digestors to run a test similar to a COD test method. Below are more detailed specifics on each test.

Photochemical Sensor for Total Organic Carbon Measurement
Analytical determination of organic load (the whole organic substance present in water as dissolved or/and in suspension form) in aqueous matrices is of continuously increasing interest in environmental chemistry. The most used indexes are BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand) and TOC (Total Organic Carbon); various normative and analytical line guides have been elaborat...

The 5-day biological oxygen demand (BOD(5)) remains a key indicator for proof of compliance with environmental regulators in the monitoring and management of winery effluent. Inter-conversion factors from alternative tests that are more rapid, accurate and simpler to perform have been determined that allow prediction of BOD(5) in winery wastewaters, generally, and at different stages of product...

متن کاملA New Approach to Total Organic Carbon Analysis Using Closed-loop Photocatalytic Oxidation
TOC is the acronym for total organic carbon. The first TOC methods were developed to correlate information obtained from chemical oxygen demand (COD) and biochemical oxygen demand (BOD) tests in drinking and wastewater. Today new government regulations are making TOC analysis a standard test for all industry water types. This paper discusses the principles of operation of common TOC methods and...
