Transcript

  • 1. Biomedical waste treatment plantSubmitted by:Kritika SarkarB.D.S final year
  • 2. Certificate This is to certify that this is a bonafide work of Kritika Sarkar of B.D.S, IV year roll no.______ and has completed the visit report on time.Verified by: Date:_________ _________Dept. ofCommunity Dentistry.HDC&H
  • 3.  Introduction. Biomedical waste Sources of biomedical wastes Segregation of wastes (at pt of disposal). Incineration : ◦ Definition. ◦ Types of incinerators ◦ Components ◦ Schematic representation of Processes involved. ◦ Effluent & air emissions. Conclusion.
  • 4. I owe my gratitude to Dr. Vinay Sureshan & Dr. Nalini Saxena (Dept. of Public health Dentistry), for there enormous support , guidance & providing the opportunity for a great learning experience.I would also like to extend my gratefulness to the my seniors and colleagues for supporting me for the preparation of this report.
  • 5.  We the students of B.D.S. IV year, HDC&H, visited Biomedical waste disposal plant- Elite Engineers, Kathonda. We interacted with the in charge, Mr. Shukla and workers, who explained how the waste was collected from different hospitals & nursing homes in color coded plastic bags and how all the procedures were carried out. We also visited different sections of the plant. We also learned about the pre-disposal measures taken before land filling.
  • 6.  According to biomedical waste (managing &handling) rules, 1998 India, “Bio-medical waste” means any waste, which is generated during the diagnosis, treatment/ immunization of human-beings/ animals, or in research actives pertaining thereto of in the production or testing of biologicals.
  • 7.  Government/private hospitals Nursing homes Physician/dentist office or clinic Dispensaries Primary health care centers Medical research and training centers Animal/slaughter houses Labs/research organizations Vaccinating centers Bio tech institutions/production units
  • 8.  Old –The process of burning, setting fire to or destroying New –An engineered process using controlled flame combustion to thermally degrade waste materials
  • 9.  ROTARY KILN FLUIDIZED BED LIQUID INJECTION MULTIPLE HEARTH CATALYTIC COMBUSTION WASTE-GAS FLARE DIRECT-FLAMEWe observed the double chambereddirect flame type of incinerator which isadequate for combustion of all infectivewaste but the disadvantage is that thereis incomplete combustion of Cytotoxicwastes.
  • 10.  Waste pre-treatment - pre- heating, autoclaving & shredding Waste loading systems – conveyors, hoppers, sprayers, manual, etc. Burner management system Combustion chambers Air pollution control device Ash and slough disposal
  • 11. Schematicrepresentation
  • 12.  This consists in sorting, separation, size reduction and sieving technologies in varying configurations to achieve a mechanical separation of waste fractions into potentially useful products and/or streams suitable for biological processing. We saw a shredder and a segregating unit for such type of treatment. Also the plastics and glass wares were subjected to autoclaving before shredding.
  • 13. Autoclave Shredder
  • 14.  The waste loading was manually done in the plant. In bigger plants is carried out by conveyors, hoppers or sprayers.
  • 15.  The chamber’s base had burners which were fueled by diesel.
  • 16. Collection of toxic emissions from the combustion chamber Emissions treated with purified water Slough comes to the surface of water Slough is separated Water resent to treatment tankswith alum, jaggery & cattle excreta.
  • 17.  The residues from the combustion chamber and the (dried) slough in collected and sent to Indore, for land filling.
  • 18. The industry visit was a great learning experience where we could see and understand the step by step processes well.
