  1. DEPARTMENT OF TEXTILE ENGINERING ETP : Effluent Treatment Plant For Textile

  2. COURSE TITLE “ENVIRONMENTAL POLLUTION AND ITS CONTROL” PRESENTATION ON “ETP OF DELTA KNIT COMPOSITE LTD.”

  3. PREPARED BY Name ID 2010000400008 Mazadul Hasan Sheshir

  4. PRESENTER Mazadul Hasan Sheshir 2010000400008

  5. WHAT IS ETP? ETP OR EFFLUENT TREATMENT PLANT IS USED TO TREAT THE INDUSTRIAL WASTE WATER. INFLUENT: UNTREATED INDUSTRIAL WASTE WATER. EFFLUENT: TREATED INDUSTRIAL WASTE WATER. SLUDGE: SOLID PART SEPARATED FROM WASTE WATER BY ETP. TREATMENT EFFLUENT INFLUENT ETP SLUDGE

  6. ABOUT THE ETP OF DELTA KNIT COMPOSITE LTD.  BIOLOGICAL ETP: TREATMENT OF WASTE WATER BY BACTERIA. TREATMENT CAPACITY: 120 m3/hr STORAGE CAPACITY: 6000 m3

  7. FLOW CHART OF ETP OF DELTA KNIT COMPOSIT LTD. INFLUENT SCREENING EQUALIZATION PH CORRECTION DISPERSE UNIT AERATION SEDIMENTATION PACK RECYCLE TANK EFFLUENT SEDIMENTATION TANK FISH POND SLUDGE THICKENING UNIT SLUDGE EFFLUENT DISCHARGE SLUDGE DISCHARGE

  8. SCREENING (DRUM SCREENER IS USED IN THIS ETP)  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. DRUM SCREENER

  9. SCHEMTIC DIAGRAM OF DRUM SCREENER

  10. EQUALIZATION EQUALIZATION IS THE PROCESS TO MAKE THE WASTE WATER- -HOMOGENOUS & -COOL EQUALIZATION TANK IS ALSO CALLED HOMOGENOUS TANK. RETENTION TIME 8 HOURSE THIS TANKA IS MADE OF RCC.

  11. SCHEMTIC DIAGRAM OF EQUALIZATION TANK SPRAY OF WATER COMING FROM DYEING UNIT COOL & INFLUENT FROM SCREENING HOMOGENOUS INFLUENT TO PHCORRECTION TANK EQUALIZATION TANK AIR FOR DIFFUSION

  12. PHCORRECTION  IN THIS TANK PHOF THE INFLUENT IS CORRECTED TO MEET THE STANDARD.  ACID OR ALKALI IS ADDED TO THE EFFLUENT BY DOZZING TO INCREASE OR DECREASE THE PHOF INFLUENT RESPECTIVELY.  MULTI-METER TYPE PHMETER IS USED.

  13. SCHEMTIC DIAGRAM OF PHCORRECTION ACID OR ALKALI INFLUENT OF DESIRED PHTO DISPERSE UNIT INFLUENT FROM EQUALIZATION TANK PHCORRECTION

  14. DISPERSE UNIT  FUNCTION OF DISPERSE TANK IS TO MIX THE SLUDGE COMING FROM RECYCLE TANK WITH WASTE WATER.  IT HELPS TO PROPER AERATION.

  15. SCHEMTIC DIAGRAM OF DISPERSE UNIT SLUDGE FROM RECYCLE TANK INFLUENT FROM PHCORRECTION TANK MIXED INFLUENT & SLUDGE TO AERATION DISPERSE UNIT ( MIXING OF SLUDGE & WASTE)

  16. AERATION  FUNCTION OF AERATION IS OXIDATION BY BLOWING AIR.  AEROBIC BACTERIA IS USED TO STABILIZE AND REMOVE ORGANIC MATERIAL PRESENTS IN WASTE.  ABOUT 200 KG AEROBIC BACTERIA IS GIVEN TO THE PLAN FOR 5 YEARS.

  17. SCHEMTIC DIAGRAM OF AERATION AEROBIC BACTERIA MIXTURE OF WASTE WATER & SLUDGE DISCHARGE TO SEDIMENTATION TANK AERATION TANK O2 AIR REACTION IN AERATION TANK: BACTERIA ORGANIC MATTER + O2 CO2+ HO2 + HEAT NUTRIENT

  18. SEDIMENTATION PACK IN THIS TANK SLUDGE IS SETTLED DOWN PARTIALLY SEDIMENTATION PACK PROVIDES THE ADVANTAGE OF FAST SLUDGE SEPARATION

  19. SEDIMENTATION TANK  IN THIS TANK SLUDGE IS SETTLED DOWN FINALLY.  EFFLUENT IS DISCHARGED FROM PLANT THROUGH A FISH POND.  SLUDGE IS PASSED TO THE THICKENING UNIT.

  20. SCHEMTIC DIAGRAM OF SEDIMENTATION TANK WASTE WATER FROM SEDIMENTATION PACK SLUDGE TO THICKENING UNIT SEDIMENTATION TANK EFFLUENT EFFLUENT DISCHARGE FISH POND FISH POND INDICATES THE HIGHER DEGREE OF TREATMENT IN THIS ETP

  21. EFFLUENT DISCHARGE

  22. SLUDGE THICKENING UNIT IN THIS UNIT SLUDGE IS DRIED AND DISCHARGED. A PARTIAL AMOUNT OF SLUDGE IS RETURNED BACK TO THE AERATION TANK FROM THICKENING UNIT THROUGH RECYCLE TANK CALLED RETURN SLUDGE TANK AND DISPERSE TANK.

  23. SCHEMTIC DIAGRAM OF SLUDGE THICKENING UNIT SLUDGE FROM SEDIMENTATION UNIT SLUDGE DISCHARGE SLUDGFE THICKENING UNIT SLUDGE TO RECYCLE TANK

  24. DRIED SLUDGE

  25. RETURN SLUDGE TANK FUNCTION OF RETURN TANK OR RECYCLE TANK IS TO MIX WATER WITH SLUDGE THIS MIXTURE IS THEN PASSED TO AERATION TANK THROUGH DISPERSE TANK.

  26. ADVANTAGE OF RECYCLE SLUDGE TO AERATION TANK  SLUDGE AGAIN OXIDIZED TO MINIMIZE THE POLLUTION FROM SLUDGE.  ALIVE BACTERIA OF SLUDGE IS AGAIN USED IN AERATION TO UTILIZE THIS BACTERIA. SLUDGE TO AERATION TANK THROUGH DISPERSE UNIT SLUDGE FROM THICKENING UNIT SLUDGE RECYCLE TANK MIXING OF SLUDGE & WATER
