PROJECT PROPOSAL - CHRONOLOGY
• Committee to examine the proposals
: December, 2010
• Examination, Conditions, recommendation of proposals
: February, 2011
• Research Advisory Committee - Recommended
: 28th February, 2011
• Admn. Approval and ES of MoEF : 6/11 April, 2011
• Suggested to seek Performance BG, TPA, Patent & MoA
Microbial consortia act on sewage to degrade into simpler forms under aerobic/anaerobic/ facultative environment-Extracellular Enzymes/Nutrients-added.
i. CPCB awarded work order to 4 firms based on AA and ES of MoEF
ii. MoA drafted for seeking concurrence of MoEF
iii. CPCB as the Nodal Agency to implement the project
iv. ‘Monitoring Committee’ at State level through State Pollution Control Board (SPCB)
v. Provision of ‘Third Party Inspection’ through IITs/ Universities
vi. Project Implementing Agencies(PIAs);• M/s Green Infrastructure, Pune (Budha Nala, Ludhiana) • M/s Amrit Clean water technologies, Gurgaon (Morigate,
Allahabad)• M/s US Environ, New Delhi (Bakarganj, Patna)• M/s Clover Organic, Dehradun (Farrukhabad, UP)
ROLE OF CPCB
Monitoring Performance at 4 locations
R & D components- Investigations
Evolving Guidelines/ Protocols.
Trainings and Mass Awareness
ROLE OF SPCBSROLE OF SPCBS UP, Bihar and Punjab to constitute ‘Monitoring Committee’
represented by Municipality, Water Supply & Sewerage Board, Jal Nigam, State Urban Authority, Irrigation Department, NGOs, etc.
Guide Project Implementing Agency (PIA) at local level-including site visits
Coordinate with PIA and concerned agencies for required clearances, if any;
Undertake laboratory analyses for performance evaluation of technology(Random-basis).
R & D COMPONENTSR & D COMPONENTS(CPCB)(CPCB)
i. Standardization of the design parameters of In-situ sewage treatment technology in terms of working methodology, microbial dosing, and working optimum ranges of pH, temperature, time, hydraulics, etc.
ii. Assessing efficacy and effectiveness of each treatment process with regard to removal of pollutants and elimination of pathogens.
iii. Developing treatment packages with microbial dosing Vs MLD of sewage to be treated and taking care of microbial population control.
R & D COMPONENTSR & D COMPONENTS(CPCB)(CPCB)
iv. Listing of microbes used in consortia to rule-out
‘secrets’ and having no doubts on harmful microbes.
v. Study the formulation of intermediary compounds for
assessing complete degradation.
vi. Studying inhibitory/ antagonistic parameters effecting
in-situ treatment.
vii. Evolving Protocol and guidelines for implementation in
other parts of the country.

WORKING PRINCIPLEWORKING PRINCIPLE
Pre-analysis of water quality for Block Placement
Installation of Bar screen to check floating materials
Installation of EBB reactor and bottom lining
De-silting of the drain at regular intervals
EBB bacteria degrade organic matters into carbon dioxide and water and helps in rapid oxidization (anaerobically) converting ammonia into nitrite and nitrate, nitrates are naturally absorbed by plants and microbes and release nitrogen gas
EBB bacteria in contact of water, propagate and multiply every half an hour to cleanse water

TECHNOLOGY: BIO-MIMICRYTECHNOLOGY: BIO-MIMICRY
Bio-mimicking designed the stretch of a drain/river enhancing self cleansing process supported by application of natural materials and NatureVel-WW products for water purification
Strategies made for adsorption, degradation, aeration, filtration and sedimentation through biofilter made of boulders, charcoal and mud balls.
NatureVel-WW, the patented product is applied/ sprayed for treatment of water pollutants
WORKING PRINCIPLEWORKING PRINCIPLE The stretch of the drain is mended as Rapids and Pool with
boulder and charcoal
The Rapids helps in adsorption, aeration and filtration of sewage and the Pool helps in sedimentation
Wood charcoal dipped in NatureVel-WW is packed in fishnet bag
Mud ball of clay and rice bran mixed with microbes are tied with charcoal balls for slow release of doses
River banks are treated and inoculated with spray of Naturavel-WW
