Organised by Planning of New CETP – Case Example of Patparganj Presented at the National Conference on “Sustainable and Environment-friendly Industrial Production” Successful Models – Performance Improvement of ETPs and CETPs PRESENTED BY Prof. S Mohan Environmental and Water Resources Engineering Department of Civil Engineering Indian Institute of Technology Madras, Chennai - 36 15-02-2019, NEW DELHI Organised by Introduction • Only 2% of the Yamuna river stretch falls in Delhi but it contributes for the 70% of total organic pollution load • Supporting DSIIDC in providing an expert assessment on the new common wastewater treatment plant is the major task • Establishment of a Zero Liquid Discharge wastewater treatment plant in the proposed site area of 6730 m2 considering environmental protection and minimizing fresh water requirement • Major step towards sustainable industrial production at Patparganj Industrial Area is to maintain a sustainable environment with minimum ecological impact Proposed site for the CWWTP at Patparganj Industrial Area NATIONAL CONFERENCE ON 2 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI Organised by Approach Followed • Zero Liquid Discharge wastewater treatment plant is proposed to be established • Membrane Biological treatment with Moving Bed Bio Reactor (MBBR) - secondary treatment considering lower area requirement and improved organics removal efficiency • Build, Own, Operate, Transfer (BOOT) business model most suitable for such projects • The design and implementation mechanism ensures efficient wastewater treatment and reuse • The Common Wastewater Treatment Plant (CWWTP) society will act as a nodal agency in case any future deviations from the desired and expected performance levels NATIONAL CONFERENCE ON 3 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI Organised by Advantages of Implementation of ZLD System • Most of the wastewater treatment plants in Delhi region are discharging untreated or partially treated wastewater due to poor operation and maintenance • Establishment of ZLD facility ensures wastewater treatment and also eliminates excessive ground water pumping by industries • The reused water is a potential water source for industries, and uniform water quality parameters is an added advantage • ZLD facility promises two way advantage of effective wastewater management and reduced fresh water consumption NATIONAL CONFERENCE ON 4 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI Organised by Learning Lessons • Involvement of all the key stakeholders is important: • MoEFCC • DSIIDC • Patparganj Functional Entrepreneurs Industrial Association • GIZ • National and International Consultant • The most critical step was to clearly specify the tender conditions • Mandatory effluent treatment system for each member unit needs to be further discussed • Awareness of the stakeholders about the importance of WWT systems, especially ZLD, is lacking • Most of the existing CETPs are overdesigned in terms of capacity thus resulting in lower operational efficiency • Incentives needs to be provided for ZLD plants NATIONAL CONFERENCE ON 5 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI Organised by Way Forward for New CETP Establishment 1.GIZ 2.IIT Madras Inputs from Apex Monitoring Committee International Consultant (Techno-economic Committee) 3.DSIIDC • The proposed design ensures up to 95% 4.CII wastewater reuse 5. PFEA • Coordination between member units and Member units CWWTP society DSIIDC CWWTP society will be key factor for effective Based on effluent Quality and Quantity operation and maintenance Vendor / Contractor (Fingerprint) • Member units will be highly benefited by the Subsidy from Govt. of India Collection Capital assistance from bank/ FI constant supply of uniform and high quality of charges Operation & treated water Built Maintenance • Potential energy recovery to attain self Evaluation of sustainable treatment facility the performance Internal Inputs from the external person Quality appointed as Chairman Committee NATIONAL CONFERENCE ON 6 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI Organised by Summary • Establishment of the new CWWTP at Patparganj Industrial Area is required to maintain the wholesome water quality of Yamuna river • Establishing a Zero Liquid Discharge wastewater treatment facility with cutting edge technology can serve as an example for others • Supply of uniform and high quality reused water will prove to be a welcome move by the industries • Application of Build, Own, Operate, Transfer (BOOT) business model through competitive tendering process helps for application of best available resources • The draft tender document has been submitted • Wastewater treatment approach needs a paradigm shift from merely meeting the regulatory standards to a sustainable resource recovery approach for environmental protection NATIONAL CONFERENCE ON 7 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI Organised by Contact Details Prof. S Mohan Former Head and Professor Environmental and Water Resources Engineering Division, Department of Civil Engineering, Indian Institute of Technology Madras, Chennai, Tamil Nadu, 600 036, India Phone: 91- 9444837600 Email: [email protected] Email: [email protected] NATIONAL CONFERENCE ON 8 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI Organised by NATIONAL CONFERENCE ON 9 SUSTAINABLE AND ENVIRONMENT-FRIENDLY INDUSTRIAL PRODUCTION, NEW DELHI.
