Pilot Testing of Bioremediation as an Alternative Treatment Technology for Municipal Wastewaters

  1. 1. Pilot Testing of Bioremediation as an Alternative Treatment Technology for Municipal Wastewaters Dr Anjana Pant WWF India, WWF India Forestry Symposium 2011
  2. 2. Structure of the PresentationIntroductionStudy AreaObjectivesMethodologyAnalysis and ResultsWay Forward
  3. 3. IntroductionWastewater (Ganga Basin) – some facts• Of the Total wastewater generated, 75% is Municipal sewage (NRCD 2006)• Of this municipal sewage, only 65% gets treated (NRCD, 2006)• Priority and focus has been on GAP towns only (due to financial limitations)
  4. 4. Wastewater treatment using Decentralized Options• Site specific: Understanding what the site allows can be economic and environment friendly• Very Low Infrastructure costs and low O&M costs• Provides opportunity to reuse treated wastewater• Energy Efficient: A forward looking plan for an energy scarce future Bioremediation is the use of living organisms, primarily microorganisms, to degrade the environmental contaminants into less toxic forms.
  5. 5. Factors governing BioremediationExistence of desired microbial population capable of degrading the pollutants;Availability of contaminants to the microbial population;Environment factors (temperature, pH, and Nutrients).
  6. 6. Study Area Key Sites River Ganga Basin Location of Target Areas for Intervention Narora Kanpur Cities Agriculture Industry ( Paper & Pulp, Sugar & Distillery, Tanneries)
  7. 7. D ZOO LAKE C B BAR SCREEN PUMPING STATION FOREST RESEARCH INSTITUTE, KANPURSHARDA NAGAR DRAIN VIKAS NAGAR DRAIN A
  8. 8. Objectives• To treat the wastewater on channel using ‘Bioremediation’ to improve its water quality to prescribed discharge standard of inland surface water by the Ministry of Environment and Forests or better, on a pilot basis.2. To reduce/eliminate the threat to the health of Kanpur Zoo animals due to the entry of sewage into the Zoo lake through the drain.3. To ensure an odorless atmosphere, devoid of microbial pathogens, to the inhabitants surrounding the drains and thus make the place more habitable.4. Demonstrate ‘Bioremediation’ as an alternative low cost sewage treatment technology which is energy efficient..

Even during times it was being pumped to another drain it was (a) polluting the other drain and also the Ganga river (b) lake received no water and hence became dry. The Kanpur Zoo had to buy water from the barrage to fill the lake which also included pumping costs.4 Bioremediation NA 39.50 Pilot Experiences
