DYEING & PRINTING & FINISHING

In any wet process house one comes across departments such as  :

Bleaching

Dyeing

Printing

Finishing

In each of the above departments lot of chemicals , dyes are used in processing.At the end of any process , the drain liquor contains lot of unused chemicals , dyes and they go to a common tank.This is called effluent and it should be scientifically treated , before letting off.

That treatment is called Effluent Treatment Plant (ETP) , where there are settling tanks,flocculation tanks,filters , and final let out into a common drain.If we take certain steps from the beginning itself , we can reduce the quantity of effluent to a considerable extent.

They are :

1. Use of minimum quantity of water.Usage of water is essential , but control of consumption is also equally important.

2. Use of optimum quantity of chemicals.

3. Use of minimum,optimum quantities of dyes in the process.

So , the more control is exercised on these above three parameters , better will be the control on final effluent discharge from a processing unit.So, means less load on Effluent  Treatment  Plant (ETP).

Many units have their own effluent treatment plant . If they can not afford to have their own , they join in a Common Effluent Treatment Plant (CETP),where dye effluent from various units is treated and then only let off.

At any given time a ETP or a CETP is a must for any wet processing unit.

Can I now invite the comments from my friends from this area of specialisation.

Environment & Pollution control

Environment :

Environment is such a very important thing to pay attention as it is to be kept well without any disturbance , change as the more we disturb environment the more harm is done to ourselves in the long run.

We all know very well that it is our basic duty to keep our surroundings very neat and tidy , as a good environment always , makes us happy and a conducive atmosphere is always welcome by anyone.

Pollution Control  :

Pollution is happening every where around us daily.It may be water pollution,Air pollution , Sound pollution , so on.Unless , this pollution is controlled very seriously , actively ,speedily we end up in living with pollution daily.See the vehicles and their emissions.The atmosphere is polluted due to these smoke producing vehicles.When we breathe that polluted air , we get chest problems , and we go to consult specialist in chest diseases. Why not adopt prevention is better than cure principle ?.

We do not bother in the beginning when we know,see pollution is happening around us . The basic reason is our own passiveness , callous attitude , always. We put off   today's prevention to tomorrow.

When we all join hands and attack the problem of pollution , we may not achieve Zero pollution , but we may reduce the pollution figures on a daily , weekly , monthly , quarterly,half yearly , yearly basis.

Where there is a will there is a way.If one is willing to accept , to reduce pollution , means we have started on a good note.Then continue this good attitude strictly and see the difference you can make on your own efforts.

So both environment and pollution control are very important and also essential

Can I now request you to share your thoughts and opinions for the benefit of all .
Thanks in advance..
