Regarding waste-water treatment to reduce BOD / COD: if we do sampling and preserve samples for BOD/ COD analysis. Then we want to apply any treatment to those samples, HOW  will we use sample, in what conditions, either the sample initially taken for treatment should also be the preserved one (acidified) or what??

And how to analyse COD/ BOD after applied treatment, should the sample be preserved again? with preservative etc. after completion of treatment process, and then test for COD/BOD again to see the difference in before and after treatment RESULTS.

F = mu x N ,

where

F = is the frictional force between the bedding and the person lying on it.

(mu) = is the coefficient of friction, representing the measure of grip between the bedding and the person's skin.

N = is the normal force, representing the force pressing the person's skin against the bedding.

In this context (mu) would depend on various factors such as the material properties of the bedding, surface texture, moisture level, and the characteristics of the persons skin.

Developing a comprehencive math model for friction (in bedding) would require more detailed analysis and experimentation to account for the multitude of the variables involved.

My research supervisor told me that I don't have enough data to do regression analysis, but she told me that she is ok with me changing research type.

Data I have:

I would be so grateful for any suggestions. Changing research concept is also fine.

Thanks in advance

p.s.: Research is done for Turkish market

I have coated emulsion through layer bi layer coating technique. after FTIR analysis there is no shift of peak occur in coated and un-coated textile. I want its description or reason behind, there might be no chemical interaction between emulsion and textile , only physical attraction that causes no shift of peak, or what else?

I am doing research on modification of Eurphorbia tirucalli latex for use in textile pigment printing and woodwork industries. The Eurphorbia tirucalli plant grows in arid and semi arid lands (ASALs) and value addition of this latex would create livelihoods in these areas (80% of Kenya Is ASALs. Please share your opinions with me.

I am working in pesticide residues analysis. I need to know about the different methods for conversion of cotton lint into cotton powder to determine the pesticide residues in it.

Thanks in Advance,

I have carried out a survey to check the health and safety practices at the textile industry. I have 199 responses for 24 attributes. I wish to use neural network to get the prediction analysis.

How to go further? What should be the inputs and outputs for the network and how should I carry out the sensitivity analysis for the same?

After getting the effluent sample from the factory, i kept the sample for a day to settle down all the suspended particles. Then i take a small amount of sample and measure the pH, the pH was 7. Then I add almost 10 gram of alum in 30 ml of sample. It coagulates the particles and the dye color is almost gone. Then i filter it, to obtain a clear solution. The pH changes to 4.2. As the water is clear, I have a question that at this stage Is Biological treatment is necessary or the Phsico-chemical method will suffice? And the pH changes because of alum then what I have to do to maintain the pH?. Can BOD and COD be removed by only this method? and by using ferric chloride and polyelectolytes this results can be achieved more better?

And actually what is the ratio of addition of chemicals as per the waste?

Kindly help me in this regards. I have attached pictures of results.

Thanks.
