Our Web site features in excess of a hundred and fifty internet pages of detailed information on our capabilities, analytical approaches, and situation histories. A printable summary of our capabilities can also be readily available right here.
Quite possibly the most skipped move by buyers in the COD Evaluation is the reagent vial inversion move. After the digestion and ahead of the vial is completely cooled, the vial must be inverted many instances.
The dichromate strategy is really a extensively used process for measuring COD. It involves incorporating a recognised excessive of potassium dichromate to your recognized quantity of sample inside the existence of sulfuric acid.
Table 1 demonstrates the typical concentrations (mg/L) of organics found in untreated domestic wastewater. This table can be employed to understand how non-sanitary course of action wastewater compares to common domestic wastewater.
This lets you guarantee the quality of your merchandise, minimize procedure and content expenses and continue to keep a constant eye with your processes to forestall financial and health and fitness damage.
Get pleasure from versatile measuring equipment with various measuring approaches in the sphere of non-damaging material testing. All instruments are made for rapidly and precise measurement.
The COD test only can take a few hours to finish, offering it A serious gain more than the 5-day BOD test. Wastewater treatment method system personnel can use COD being an almost actual-time operational adjustment parameter.
The key distinction between BOD and COD is that BOD is the amount of oxygen which is eaten by microbes whilst decomposing natural issue underneath aerobic disorders Whilst COD is the level of oxygen needed for the chemical oxidation of total organic & inorganic matter in H2O.
The COD test employs a chemical (potassium dichromate inside a 50% sulfuric acid Option) that “oxidizes” both equally organic (predominate) and inorganic substances in a very wastewater sample, which ends up in the next COD concentration than BOD concentration for a similar wastewater sample considering that only natural compounds are eaten during BOD testing.
Large COD amounts suggest a significant amount of oxidizable organic material in the answer, that may cut down the level of dissolved oxygen obtainable for aquatic life.
Discharge limits vary from plant to plant depending on the attributes of the getting get more info drinking water, consequences on aquatic lifestyle, recreational takes advantage of together with other aspects.
We provide different test techniques for product testing. The bottom materials and the coating substance in the test component select which measuring approach is suitable for your software.
Conductivity measurement lets you indirectly Look at the composition of metals on The premise of conductivity in a non-destructive manner. As the reciprocal get more info of electrical resistance, conductivity not just indicates how effectively a metal conducts electric present: Conductivity measurement also indirectly offers details about the microstructure, mechanical Attributes and adjustments inside the composition of a material.
The COD test can be utilized to find out the toughness of wastes which might be too toxic for being tested as a result of working with BOD test.
