  1. The Siam Construction Steel Co., Ltd. SCSC ENVIRONMENTAL CONSERVATION & IMPROVEMENT

  2. Location • The Siam Construction Steel Co., Ltd. (SCSC) , • a part of Tata Steel (Thailand) Public Co., Ltd • Locate in Map Ta Phut • Industrial Estate , • Rayong Province , • Thailand. asianinfo.org

  3. Production Process SCSC Product Reinforcing Bar Steel Bar

  4. Environmental Improvement • The improvement that SCSC try to accomplish • Air pollution management • Wastewater management • Waste management

  5. Environmental Improvement • Air pollution management 2 units of Bag house filter plants.

  6. Improvement for Air pollution control • Install new bag house filter plant • (Fume 2) and new natural cooler. • Benefit • Increase capacity of dust collecting. • Increase efficiency of air cooling. • Increase capacity of bag house.

  7. Improvement for Air pollution control • Check and repair damage wall to • reduce dust leaking out at bag house. • Benefit • Reduce dust leaking out at bag house. • Protect water and Moisture leak into bag house. • Increase efficiency of air cooling.

  8. Improvement for Air pollution control • Install new filter bag and repair venturi cone. • Benefit • Improve efficiency of dust collecting. • Reduce dust leaking from stack. • Increase efficiency purging system.

  9. Improvement for Air pollution control • Coat the deck floor and wall of bag house. • Benefit • Protect water and Moisture leak into bag house. • Increase efficiency of purging system. • Increase life time of bag filter.

  10. Improvement for Air pollution control • Modify chain conveyer. • Benefit • Reduce residual dust in bag house. • Reduce frequency of manual drain residual dust to floor. • Increase life time of bag filter.

  11. Improvement for Air pollution control • Check and improve purging system. • Air purging process (pressure • & frequency). • Chamber gate (open & close • system). • Benefit • Increase efficiency for cleaning bag filter and extend the life of filter bags. • Increase efficiency of bag house. • Increase capacity of bag house.

  12. Improvement for Air pollution control The result of opacity analysis from CEMs. Bag house filter 2 Bag house filter 1 mg/m3 mg/m3 Before modify Before modify After modify After modify Note : Standard not over 240 mg/m3 Conclusion The result of opacity analysis show after improve and modify dust opacity (emission from stack) was decrease. And the stability of bag house filter plant was increase.

  13. Improvement for Air pollution control • Protection of dust spreading whileunloading scrap. Before After Benefit : Reduce effect from dust emission. Note : Now SCSC planning to reduce the SO2 , NOx and CO2 emission through the conversion of heavy oil to natural gas in the reheating furnace in year 2011.

  14. Environmental Improvement • The improvement that SCSC try to accomplish • Air pollution management • Wastewater management • Waste management

  15. Environmental Improvement • Wastewater management • Wastewater from production process. Raw water Treatment plant Production process Wastewater treatment Irrigation pond Reuse Retreatment & reuse in process • Wastewater from office. water supply Office & Toilet Wastewater treatment Drainage Water water gutter Reuse (plan)

  16. Improvement for wastewater management • Install filtering system at water gutter at I7 • road gutter and I8 road gutter before drain to • public source. • Benefit • Reduce contaminate by dust and particle in • drainage water. • Reduce garbage and Waste leaves collected in • gutter.

  17. Improvement for wastewater management • Improve all water gutter in SCSC for zero discharge water. • Benefit • Reduce drainage waterto zero discharge. • Collected drainage water and reuse.

  18. Improvement for wastewater management • Re-routing wastewater from scrap • yard to treatment and reuse. • Benefit • Reduce drainage waterto zero discharge. • Collected drainage water and reuse. • Reduce impact of wastewater

  19. Environmental Improvement • The improvement that SCSC try to accomplish • Air pollution management • Wastewater management • Waste management

  20. Environmental Improvement • Waste management

  21. Improvement for waste management • Study to use for raw material in Zn • Recovery process. • Benefit • The benefit use of natural resources worthily and • maximize value. • Reduce waste disposal by landfill or security • landfill. • Reduce Cost of waste disposal.
