Chemical Oxygen Demand

1.I working for pickles food company, we are having a problem with our COD and BOD, please help ,how can we solve it, but our effuent results, in term of pH and Tss are good.please help me urgently.

2.I want to know that how calculate COD and BOD? pls help me.

3.How can you differentiate between the COD and BOD?

4.Give the information how to calculate %oxygen consume.i mean formulas



5.Raw effluent of Pharma company the cod, bod is high how to reduce the cod & bod. & how to design the aeration tank capacity.

I want to know about the difference between COD & BOD.

After chlorination COD will increase or decrease?Because chlorine is also one of the oxidizing agent. it may interfear with the interference of pottassium dichromate as an oxidizing agent?

Rescepted sir,

Please sir tell me can we increase the COD of perticular organic material and how?

can u tell me why we use sulphuric acid for COD determination?

plz inform method to minimize COD, its about 15,000mg/l.

I run a number of Extended Aeration and Sequential Batch Reactor portable Waste water treatment plants, what steps can I take to ensure that the COD and BOD in the final effluent produced have minimal impact on the receiving environment. An example of two succesive samples are as follows 1st ph 7.2, tss 21, BOD 97, COD 340,

2nd ph 6.8, tss 53, BOD <4, COD 500,these are of from the same unit two weeks apart! Any insight is sincerely appreciated

Good day sir...

Sir,i want to know how to reduce or decrease COD and BOD levels at industrial waste water or effluent...? In my company COD and BOD levels are very high, up to 1000 ppm. Please help me..

I'm waiting for your answer.! Thank's...

Dear sir,

Please tell me How to calculate COD and BOD and Procedure.

what factors correlate cod and bod

very good

Please tell me the calculations of COD ?

how we maintained the cod under control limit if more than >2000 ppm but my ph >7.0.

Give the information how to calculate %oxygen consume.i mean formulas

Please tell me ways I can reduce COD/BOD levels in industrial waste water.

Sir,recently we are doing a project by performing cod test on effluents coming out of some famous industries...could you please help us by cleary giving the details of the chemicals and reagents to carry out this test?

Hi,
Thanks for such an excellent publication. After reading it, i realized that my doubts about the difference between COD and BOD were cleared.However, please include some quantitative analysis and laboratory procedures.

may i know how to deacreas the COD of the water.without effecting conductivity of water.

How can I reduce the COD of wastewater sample when I'm getting already BOD5 less than 5 ppm.

When applying regression statistics to problems relating the biochemical oxygen demand (BOD) and the chemical oxygen demand (COD), which is the dependent variable and which is the independent variable?

why cod is higher than bod?please reply

tq. for the explanation. now i got some view.

may i know any efficent and judicious technique to reduce cod

why cod is higher than bod?mirch masala's company cod can come higher?please reply

what is the samling protocl in getting the COD???

Hello sir

I want to know that how calculate COD and BOD? pls help me.

Plz tell me in a lake eco-system for poluuting the lake how COD contributes?

I also want to know is there any relation ship between BOD and COD?

what is the relation between COD & PH ?

Thank you

this is agood data

Is there any other method to calculate the COD without using the formula.

8000(b-a)n/vol. sample

Sir,

we use sulphuric acid to neutralize spend caustic but stil we found high COD.

Did you have any way to reduce the COD?

Good day. We have analyzed our BOD and COD content on our effluent. How come our BOD passed the regulatory limit while the COD failed? How can I reduced COD on our effluent?

I work for a processing industry. Please tell me ways I can reduce COD/BOD levels in industrial waste water.

Sir,

Pl elobrate on the areas where to opt for BOD Or COD test.Further,kindly share a tabulated comparison of COD and BOD covering the aspects of technicalities,conditionalities and the economy.

Regards

Sir I want to know the Parameter of Piclking industry wastewater ie COD,BOD,TSS,PH, kindly provide me this information as soon as possible.

Method analysis for Chemical Oxygen Demand

i need units for cod,bod,tds, tts,alkalinity,acidity,etc.,

Pl provide all answars of below questions

i need poroje about cod

what is the function of adding mercury sulphate in the water samples?

when i found to this website im quite interest to write some idea to nilu..what do means to prepare reagent. is it reagent for cod testing ?

How can you differentiate between the COD and BOD?

i want to know the effect of the Biological Oxygen Demand, Chemical Oxygen Demand and the Disolved Oxygen when it has high concentration.

thanks in advance. whats the relationship between COD and BOD- Is it possible to use biological means to reduce cod.

Hello sir, I want to measure H acid degradation by white rot fungi. I want to know is it possible to measure its degradation by COD? Can I determine its degradation using COD?

Good Day, I would like to know why do we add minerals in dilution water like MnSo4, FeCl3. What are the effects of this compound to the dilution water? What is the purpose of Glutamic acid or GGA that we used in our standard? And most important the purpose of SEED in the analysis. I was just curious in the addition of dilution water that we used to fill up the BOD bottle to 300 ml. Thanks...

plz tell me the standard procedure 2 calculate the cod that means i want 2 know the materials required, reagents
requered,procedure, observation table, formula, precaution etc related with during cod measurement during lab

dear sir can we measure O2 by Using IR source. Plz tell me about this briefly, if we can measure, why & why not?
