Common use hach cod vials for measuring water quality

The most common application of COD is in quantifying the amount of oxidizable pollutants found in surface water (e.g. lakes and rivers) or wastewater. COD is useful in terms of water quality by providing a metric to determine the effect an effluent will have on the

For determination of high range Chemical Oxygen Demand (COD) by the Reactor Digestion method. US EPA approved for wastewater analysis using Hach Method 8000. Range: 20 -1500 mg/L COD. Pack of 25

Chlorination is the common disinfection method used for source water with minimal organic contamination and low concentrations of difficult-to-treat microorganisms, like giardia or cryptosporidium. It is also used for taste and odor control, prevention of algal growths, maintaining clear filter media, removal of iron and manganese, destruction of hydrogen sulfide, cyanide and improving

A clear view into the quality of your water. Turbidity can be measured by the cloudiness in liquids. Turbidity, a measure of cloudiness in liquids, has been recognized as a simple and basic indicator of water quality. It has been used for

2010/10/14 · The most popular current testing method for COD involves using sealed and heated (i.e., closed reflux) low-range (3-150 ppm) or high-range (20-1500 ppm) pre-prepared vials that change color from orange to green based on the

Digestion Reactors Easy to use and fast, safe to operate and versatile, Hach DRB reactors accommodate most test vials. Choose a dual block for running two programs at the same time. Reagents Hach's USEPA-approved dichromate COD Method is the most widely used chemical oxygen demand method in the world for NPDES reporting and for easy process monitoring.

2005/06/01 · We use 3-to-150 mg/L COD digestion vials for our effluent tests and 20-to-1500 mg/L vials for our influent tests. After 3 mils of sample are added to a vial, the vial is capped and placed in the reactor to digest at 150 C for two

Quality dilution water is very important when testing BOD, as any contamination in the water will cause problems with the test. Distilled and deionized water are commonly used in BOD testing. However, the most practical way to consistently produce water of low
