Chemical Oxygen Demand (COD) analysis is a measurement of the oxygen-depletion capacity of a water sample contaminated with organic waste matter. Specifically, it measures the equivalent amount of oxygen required to chemically oxidize organic compounds in water.

R 1,335.37 – R 5,520.00 inc VAT. COD vials for testing Chemical Oxygen Demand. One of the most common tests used in effluent testing. Vials are available in 16mm format or the LCK 13mm format. Standard vials and Mercury Free.

CHEMetrics offers two Dichromate Reactor Digestion Methods for the fast, easy and safe determinations of Low, Mid, and High Range COD in wastewater: USEPA-accepted Method and Mercury-Free Method. Mercuric Sulphate is used in the former method to eliminate Chloride interferences. If negligible Chloride interference is expected, then the Mercury-Free

Chemical Oxygen Demand (COD) is the amount of oxygen taken from the oxidant for chemical oxidation of organic matter and some inorganic compounds like nitrites, sulfates, etc. [9] [12]. The COD of sludge wastewater can vary ranging between 850 and 5000 mg/L, it can also increase up to 15,000 mg/L.

2014/12/1 · The objective for this paper was to develop a high throughput methodology to determine chemical oxygen demand (COD), five-day biochemical oxygen demand (BOD 5) and other water quality parameters via turbidity measurements of the treated effluent that has residual suspended microalgae.

5220 CHEMICAL OXYGEN DEMAND (COD)*#(102) 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is
