There are lots of procedures for measuring COD, Every single with its benefits and drawbacks. The commonest procedures incorporate the dichromate strategy, the permanganate process, plus the closed reflux process.
Insert the COD test vial in to the sample compartment making sure it’s correctly seated and again press the Zero/Test vital.
The dichromate process is often a greatly used approach for measuring COD. It involves incorporating a known excessive of potassium dichromate to a regarded volume of sample in the existence of sulfuric acid.
COD Investigation consists of using a strong oxidizing agent to oxidize the organic compounds inside the sample, as well as consumed oxidizing agent is then measured to determine the COD worth.
Substantial COD concentrations in wastewater indicate the presence of organic and natural substances that may decrease the level of dissolved oxygen.
With our MMS® Inspection DPM tactile measuring device for dew point measurement, you may reliably and non-destructively report relative humidity, air temperature and surface temperature.
BOD refers to the biological oxygen demand, which steps the level of dissolved oxygen (DO) necessary by aerobic organisms (oxygen demand) to stop working organic waste content current inside a offered water sample at a specified temperature and specified time.

The electrochemical water measurement principle is a way used to analyze and evaluate various read more parameters in h2o determined by electrical alerts produced all through particular electrochemical reactions.
This glossary report aims to supply an in-depth understanding of Chemical Oxygen Demand, its significance in wastewater treatment, as well as the strategies used for its resolve.
For additional basic safety, look for versions that have an optional protect that handles the heating block in the event of a collision.
Divide the COD focus via the BOD focus for each sample and website ordinary the outcomes. One example is, underneath could be the COD:BOD ratio made utilizing three wastewater samples from a food items processor:
Because of this, these reagents are ideal for plan analysis the place no or very reduced chloride concentrations are anticipated.
This process has actually been uncovered successful in the event the proportions and kinds of elements inside of a wastewater keep on being rather regular.
