Pollution is the discharge of unwanted material, residue and
energy into the environment. Some of these residues are unconverted raw
material, some are uncovered products and some are by products produced during
the manufacturing or processing. In other words, pollution is a sign of
inefficiency in industrial production and it can be considered as money that is
going up the chimney, down the sewer and out of the plant in waste truck, thus
causing loss to the manufacturer.
The pollution in a composite textile mill can be
categorized into three groups:
- Air Pollution
- Water Pollution
- Noise and Vibration Pollution.
Of these, water pollution is more significant compared to
other pollution.
Water pollution:
Textile industry is one of the leading consumers of water.
It consumes about 3.2% of total consumption of water for various processes such
as sizing, scouring, bleaching, dyeing, printing and other finishing processes.
The used water containing various constituents such as dyes, chemicals is
directly released into the sources of water which gets contaminated and thus
resulting into water pollution. Nowadays the use of synthetic fibres, polymers
and finishes by textile industry is increasing at rapid rate. Since many of
these products are resistant to biological degradation, it causes water
pollution when released as effluent into the water sources.
The seriousness of water pollution depends upon how
effectively the above processes are carried out and also the quantity of water
as well as the substrate or the chemicals used in processes.
