Avantu presentation 2

  1. 1. The main cause of the problems Hydraulically overloaded systems Insufficiently trained operators Lack of sewage maintenance & budget Insufficient staff to run the sewage program & bureaucracy Insufficient retention time to biodegrade Low or incorrect biomass
  2. 2. Some methods to remedy the sewage problems to remove sludge
  3. 3. Another method to remedy the sewage problems
  4. 4. Very dangerous way
  5. 5. Environmental way?
  6. 6. Still another
  7. 7. Another innovative way
  8. 8. Very expensive way
  9. 9. OR Do what nature has been doing for millions of years – biologically Avantu’s concept of adding (augmenting) the RIGHT bacteria (bio) to increase the correct biomass to accelerate the biodegradation process to rectify the problem
  10. 10. BIOAUGMENTATION Bacteria/micro-organisms have been scientifically selected for their biological performance in the breaking down process of sewage & other organic waste Balance/adjust the bacteria biomass “blend” to remedy the problem The answer is in the sewage problem itself
  11. 11. The Avantu Natural WayThe bioaugmentation products
  12. 12. Acceptance of“Bioaugmentation” 1995 16 000 Pit toilets & Aqua-Privies were dosed and remedied in Ivory Park - 1995. Selected locals were trained to implemented the dosing under supervision. The cost was approximately 30% of the Vacuum Tanking cost normally used.
  13. 13. Water & SanitationLocal Government Digest – 1996 After a number of observations of the success of Avantu’s “Pitking” Bioaugmentation product, the attached article was published. During this period “Fatking” was developed.
  14. 14. DWAF – Scientific Services Report-2003 Dr. P L Kempster evaluated Avantu Bioaugmentation products. The report states that “bioaugmentation is a well recognised and researched method of speeding up biological degradation of domestic waste”.
  15. 15. The report further confirmed that “Bioaugmentation”Biodegrades solid sewerage in basic systems, Pit toilets, septic tanksRemoves the smell within 24 hoursPrevents the spreading of waterborne diseases including cholera.Accelerates the biodegradation process in hydraulically overloaded systemsSewerage System’s final effluent will conform to discharge standard
  16. 16. Avantu Products RectifyAll Sewage Organic Problems: Pit Latrines & VIP Septic Tanks, Fat Traps & Aqua-Privies All sections of Sewage Treatment Works Sewage Spills in Rivers & Dams Hydraulically overloaded STW Kick starts new systems Rectifies systems that have had hazardous chemicals kill off the biomass Control Waterborne diseases and Mosquito & Black fly larvae
  17. 17. United Nations – Human Development Report 2006“Every $1 spent in the sewage sector creates on average another $8 in costs averted and productivity gained.”
  18. 18. Avantu Successes -HloHlo Ponds - Lesotho
  19. 19. Avantu Successes -HloHlo Ponds- Lesotho 1 week after dosing started
  20. 20. Avantu Successes -HloHlo Ponds- Lesotho 2 week after dosing started
  21. 21. Avantu Successes -HloHlo Ponds- Lesotho 2 week after dosing started
  22. 22. Avantu Successes -HloHlo Ponds - Lesotho 4 weeks after dosing started
  23. 23. Avantu Successes -HloHlo Ponds - Lesotho 6 weeks after dosing started
  24. 24. Dispatch Maturation Ponds – Case Study Congested Maturation/Holding Pond with years of buildup of stabilized sludge. The sludge was not breaking down as fast as expected so analysis of the effluent was taken, the results were: Total Dissolved Solids 1672; Magnesium 177 and Ammonia 250, very difficult sludge to biodegrade.The senior consulting engineer, Johan Barnard,confirmed that the bioaugmentation had reducedthe sludge by 80%, email above
