  • 4. Total Textile Process at a Glance
  • 5. Presentation on Biochemical ETP 5
  • 6. Effluent is the stream of excess chemical liquor which is extracted from an industry after using in original operation. The excess dye liquor which is extracted from textile industry after dyeing from different processes are treated with various chemicals to remove or neutralize the toxic materials before discharging to environment (e,g- ground water) . This is called effluent treatment. Presentation on Biochemical ETP 6

  • 11. (DRUM SCREENER IS USED IN THIS ETP) Presentation on Biochemical ETP 11  Screening is the filtration process for the separation of coarse particles from influent.  Stainless steel net is used for screening.  Hard plastic brushes are used to clean the net, which are driven mechanically.

  • 15. Ozone contact tank is used to_____ Remove color Add more DO Kill Anaerobic Bacteria O3 is create by Ozonator Presentation on Biochemical ETP 15 This tank is made of RCC Capacity : 31.08 m3
  • 16. FLOCCULATION TANK IS USE FOR____FLOCCULATION TANK IS USE FOR____ Coagulant-flocculants (lime, ferrous & polymer) Break down Color Bond Decolorant This Tank Is Made Of RCC Capacity: 31.08 m3 Presentation on Biochemical ETP 16 According to IUPAC “flocculation is a process of contact and adhesion whereby the particles of a dispersion from larger size clusters” Flocculation process in ETP means increasing the particle size.
  • 17. Presentation on Biochemical ETP 17 SOLOD AND LIQUID SEPERATION PART. CAPACITY : 70 m3 Primary secondary and tertiary settler ___rack of inclined metal plate, which cause flocculated material to precipitated from waste water.
  • 18. Presentation on Biochemical ETP 18 THIS TANK IS MADE OF RCC CAPACITY: 842.4 m3 Sequencing batch reactors are industrial processing tanks for the treatment of wastewater . SBR reactors treat waste water from industrial area, and sewage or output from anaerobic digesters or mechanical biochemical and biological treatment facilities in batches, Oxygen is bubble through the waste water to reduce Biochemical oxygen demand (BOD) , chemical oxygen demand (COD) to make suitable for use in land and aquatic life. Here used bacteria should be aerobic,
  • 19. Presentation on Biochemical ETP 19 CAPACITY : 375.76 m3 Generally use to reduce temperature and increase DO. To storage the wastewater for next treatment.
  • 20. Presentation on Biochemical ETP 20 THIS TANK IS MADE OF RCC CAPACITY : 245 m3 Aerobic digestion is an open system that utilizes oxygen and biologically treats waste with naturally occurring organism.

  • 24. AcknowledgementAcknowledgement Presentation on Biochemical ETP 24 At first we want to give thanks to our honorable course teacher Assistant professor Dr. Arun Kanti Guha, for assigning us for this important assignment and also for his immense help in during making this assignment paper. We also want to pay thanks to our senior brother Mazedul Hasan Shishir (13th batch) for his help and support. At last we want to pay thanks to our group members for help and co- operation with hard working mentality so that we could complete the task with success.
