Chemical Oxygen Demand (COD)Introduction:The Chemical Oxygen Demand (COD) test is the standard method for measuring the amount of pollution in a sample that is unable to be oxidised biologically.Oxidation takes place on both the organic and inorganic component but as the organic component is more dominant‚ it is of more significant interest.In the COD test‚ the amount of oxidation that takes place depends on sample COD concentration‚ digestion time

games. The reason is because there is only one military based game that is dominating the market every year is Call of Duty. As a COD (Call of Duty) player myself‚ I have been since Black Ops. So I can understand the appeal of these games‚ single player campaign in COD offers some of the exhilarating action. I never knew that there would be a FPS that could rival COD until I played Battlefield 3.

reactor was started-up in step-wise loading rates beginning from 0.05kg carbon oxygen demand (COD)/m3-day to 3.50kg-COD/m3-day. The hydraulic retention time (HRT) was slowly decreased from 96 hrs to eight hrs. It was observed that the removal efficiency of COD of more than 73% can be easily achieved at an HRT of more than 16 hours corresponding to an average organic loading rate (OLR) of 3.0kg-COD/m3-day‚ at neutral pH and constant temperature of 29oC.

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 expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

(AOX) and the chemical oxygen demand (COD). The pulp and paper industry is one of the major industries in India causing water pollution. The manufacture of paper yields a significant quantity of waste-water. It is estimated that 273–450 m3 of water is required to produce 1 ton of paper and about 60– 300 m3 of wastewater is discharged (Subramanium 1976; Thompson et al.
