Pollutants,pollution and control in textile industry

  3. 3. INTRODUCTION  Textile industry is concerned with design and production of yarn and cloth and their distribution.  Textile industry comprises large quantity of water and also need various chemicals and dyeing agents for the process.  Here arise large quantity of waste in terms of water, energy and other chemical substances which will directly or indirectly affects the environment.  The pollution may be in the form of air, water or noise .
  4. 4. WATER POLLUTION
  5. 5.  The consumption of water includes various processes such as sizing, dyeing, and other end product processes.  The major problem arises chemicals are directly discharged into water bodies.  This water pollution not only affects human beings and house hold animals but also aquatic animals.
  6. 6. EFFECTS OF WATER POLLUTION  Depletion of dissolved Oxygen  Hinders with self purification process of water.  Clogs the pores of the soil resulting in loss of soil productivity.  Corrodes and incrustates the sewerage pipes.  Effects the quality of drinking water in hand pumps making it unfit for human consumption.  Leads to leakage in drains increasing their maintenance cost.  Impurities in water affect the textile process in many ways.
  7. 7. MEASURES TO CONTROL WATER POLLUTION Effluent treatment methods can be classified into :  physical,  chemical and  biological methods;
  8. 8.  Exclusive treatment by one of these three methods has proved to be insufficient in removing colour and other effluent from textile industry wastewater.  Combination of various effluent treatment methods can remove more than 85% of unwanted matter.  Adoption of best practices:-  Reducing and Recycling Water  Awarness to go green  Practice “Air Dyeing Technology” Air Dyeing Technology is a dyeing process that uses air instead of water to dye garments, allowing companies to create garments with vivid designs and colors, without polluting the water and environment .
  9. 9. • Bleaching : Chlorine bleach is extremely toxic. An alternative method which is oxygen-based can be used. • Functional Finishes :Rather than using harsh chemicals to soften and finish the fabric a finish made of bees wax, Aloe Vera and Vitamin A are a good alternative. • Sizing :Instead of the use of polyvinyl alcohol (PVA) for sizing use of potato starch or carboxymethylcellulose (CMC) .
  10. 10. AIR POLLUTION
  11. 11.  The major air pollution problem in the textile industry occurs during the finishing stages, where various processes are employed for coating the fabrics.  Air emissions include dust, oil mists, acid vapours, odours and boiler exhausts.  Speculation concerning the amounts and types of air pollutants emitted from textile operations have been widespread but, generally, air emission data for textile manufacturing operations are not readily available.
  12. 12. EMISSION OF POLLUTANT:  EFFECTS OF POLLUTANTS :
  13. 13. MEASURES TO PREVENT AIR POLLUTION:  In order to prevent the hazards emission from the industry the workers can be advised to use Material Safety Data Sheets.  Staff members who regularly handle the chemicals can be given adequate training regarding the over usage of particular chemical and their ill effects on health and environment.  Height of chimneys should not be less than 30m so that all deadly gases are released out of the living organisms.  Settling chamber should be used  Filtration method can also be used for filtering the hazardous pollutants in which bed filter, fiber filters and fabric filters are widely used.
  14. 14. STEPS IN RISK MANAGEMENT:-
  15. 15. CONCLUSION  In order to protect the environment every organization should regularly check and file the documents related to regulations concerning work place safety.  The management must ensure that the organization has protocol to implement all the rules regarding the environmental and workers safety  The workers of the textile industry should ensure that the production area is distant from the place where they take food in order to avoid the consumption of chemicals through air.  Thus all people must be careful towards the hazardous substances that pollute water and air substantially , their sources and the steps to assess and control the risk in the textile industry
