Greetings sir,
i am sarav, i am a chemical engineering student final year,
i am required to design an Adsorption column using Activated Carbon to remove the colour of textile dye effluent, i am totally bank at this moment
kindly guide me to achieve this..

Thanks in advance

This is an almost identical topic to what you can find at:

http://www.cheresour...6934#entry46934

You either have the required training and preparation for process designing an adsorption column - or you don't. Which one is it? If you do have prior (or present) training and instructions on the subject, then refer to our comments and recommendations in the above thread. After applying those principles, if you have any further problems and/or questions, return to our Forum with those specifics and we can address them then and try to help you out.

If you do not have the training and preparation, then you really have no business trying to beat an elephant with a straw. You must acquire the proper tools. We can't give you those tools here in the Forum - but we can show you how to use them (or use them better or more efficiently). But you must first start out using your own tools first.

Thank you very much sir,
i have previous exposure to adsorption
I have done calculation in our academic part.
there the problem is provided with necessary data, but i dont have any practical exposure to adsorption design and i dont know how to obtain the necessory data.

And also i dont know what are the data required to design an adsorption column.
So kindly help me...

you have also mentioned about tools, i dont know what are u mentioning about
i have some tools such as, Aspen, CAD, etc.,

Like most (or all) the experienced engineers on our Forum, I want to help you – but I am having a very hard time understanding what you are saying. I don’t mean that I don’t understand your writing. You write very well. What I don’t understand is your logical (or unlogical) statements. For example:

You state you have had previous exposure to the adsorption process and you have done calculations in your academic course where the problem is provided with the necessary data. However, you state that you don’t know what are the data required to design an adsorption column – nor do you know how to obtain the necessory data. This is not only strange, but not logical. If you have already calculated an adsorption process, you should be able to duplicate the effort. If you have been given the basic data for the calculated problem, then you know what that basic data is. You used it to solve the prior problem, isn’t that correct? Then you do know what basic data is required to solve a similar problem – you used it in your previous problem. Have you forgotten what you did or did you lose your prior calculations?

The engineering tools I am referring to are your theoretical training and your practice problems (like the prior one you already worked out). Using that and the engineering logical approach that you have been taught to such problems, you are expected to resolve the given task. I do not believe that a respected university is going to assign you a problem that you have not been trained or lectured on. The university is not in the business of mental torture and subjecting you to anguish and ultimate failure. I realize that to a young student it may seem that way sometimes, but that is not true. The university is responsible for training you in solving these type of problems and prepares you through lectures, labs, homework, and counseling. You are supposed to use all those resources to solve the problem.

If I wanted to do your work for you and design the adsorption column(s), I couldn’t even start to do it because I know nothing about it. You have furnished our Forum with absolutely NO BASIC DATA OR BACKGROUND INFORMATION. All you have furnished is a plaintive plea for help – but you have not identified what you need help in. You must start the procedure of resolving the problem – BY YOURSELF. You must do the initial attack on this challenge. We cannot do that for you. We will help you work it through with explanations to specific areas or sections of the problem that you may not understand or have trouble with. But we cannot give you the answer. That is your job.

All engineering problems require some sort of algorithm – whether mathematical or just common sense. It is very much like a game plan on how to attack and resolve the problem you confront. That is first thing that should be taught in any engineering curriculum in a university. I am certain that you have been taught that. If you could at least present the Forum with your algorithm and your organizational plan on resolving this problem, we could help you by commenting on it and checking your logic and correct problem solving technique. But, once again, YOU MUST START THE MENTAL LABOR of resolving your problem.

We all want to help you succeed. Doing your work and your thinking for you is not helping you in engineering. It would be hurting you instead, because you will not have learned how to attack and start in on resolving all the future problems that await you in the future. Engineering is TOUGH. We all know it because we have all gone through those trials and tribulations. Engineering is probably the toughest career course in any university. Therefore we expect hard and taxing problems in order to qualify for graduation in engineering. But while engineering courses are demanding and tough, they are not unjust. Hard work and hard studying can defeat an engineering course.

I sincerely hope I have made a point with you and that you will apply all the knowledge and training you have received to this problem. We await an opportunity to help you in specific areas with counsel, checking, and comments. But we can't offer you the answers.

Thank you very much for your time sir,

i understand my lack of knowledge in subject, i am not a bright student in my class

Actually my final year project is to design a system to treat textile effluents bcoz this is the major issue in our city.
My concept is to treat tat effluent using RO, and we planned to introduce adsorption column to remove colour from that effluent i read tat colour has some ill effect on ro membranes

i gone through some papers from science direct which is related to treatment of textile effluent using activated charcoal, there they proposed many models in their papers by conducting experiments. There they summarized effect of bed height, concentration, etc., should i also need to conduct such experiments to use their model?

For studying the reverse osmosis performance, i studied a reverse osmosis plant in my city. There they used activated carbon filter to remove chlorine from sea water. So can i apply the same ACF to remove colour from effluent or is i must to go for an adsorption column. What is the difference between them sir?

pls forgive me if my questions are silly..

i am ready to put all my effort, kindly suggest me any books tat i must go through.

i am totally impressed with this forum i have gone through some posting and i have hope that i can get help from this forum
