Textile Dyeing Pollution & Solution I

These are not funny photos! It is a sad and terrifying reality!

Dye-making units in Gujarat Industrial Development Corporation’s, Vatva patch area have transformed a man to Orange color, a dog to Blue color and a Squirrel to Blue color!^[1]

The Krishna river stretch in Telangana in India is polluted by 15 million liters per day from 5 municipalities along it.[2]

5.9 trillion liters – The amount of water used each year for fabric dyeing alone. (World Resources Institute).[3]

WASTEWATER TREATMENT ISN’T ENOUGH!

WHY?

1.       The dyeing mills wastewater treatment is difficult and costly as quantities are enormous and almost impossible to do indoors. Big dyeing mills pour their effluent either into rivers or into collective pools with wastewater from other sources (municipal waste) and pollute them with industrial textile dyeing toxic waste. Municipal waste should be treated alone.

2.       To be effective, this needs a lot of space for coagulation – it is the best way for wastewater treatment, in my opinion, for the following reasons:

a.       Dye molecule chemical composition is very complicated and not easy to break down (Degrade) into simple compounds.

b.       Generally, some chemical processes are applied to degrade the dye molecules and other chemicals to remove the color, then filtration or other means. The resulting compounds from the dye molecule degrading - parts of it - can pass through filters and cause problems unless using a variety of filter types - very expensive!

c.       We should keep the dye molecule in its bulky form to avoid side, unknown and invisible products formation resulting from degradation.

 

3.        Lack of reliability is a big challenge. It is too hard to track and check every single dye house for the use of non-toxic dyes and chemicals.

4.      The most important fact is that wastewater treatment processes are not enough to compensate for the consumed and polluted water.

SOLUTION

A.      Stop dealing with big polluting factories.

B.      Start encouraging small-sized mills to start up units with wastewater treatment plants. The smaller the quantity of wastewater, the easier it is to be treated and controlled.

C.      A small production unit with a digital dyeing technique will save up to 70% of water consumption and minimize polluted water quantity to easily clean, can be installed anywhere, and circulate the water quantity so as to reach zero water consumption.

D.      Here magnifying (Coagulation) is ideal as quantity of water is much less, consequently no problem for sludge collection.
