Slide1
Sustainable Industrial waste water management
Jyoti Palekar - STEP Private Limited
Slide2Effective performance and Sustainability of wastewater management Facility:
Optimum Design
Installation as per design
Receipt of waste as per design parameters
Effective and efficient operation
Slide3Sustainability - What are the real Issues??
Slide4Action Point-1 Assessing and managing
water footprint- Water Audit
Cost Saving:
Reduction in volume of freshwater used for production and entire value chain
Reduction in wastewater volumes and treatment costs
Water Audits Key Components:
Identify water consumption sources and develop water balance
Measurement, Monitoring & Reporting of water footprint
Identify interventions for improvement of footprint, benchmark setting
Awareness and training
Slide5Increased financial investment
Increased utilization of resources
3 R principles in Water Footprint
1
S (segregation) and 1 M (measuring) principles
Add 1S and 1 M in R
Slide6Action point 2
Strategy for Wastewater Management….
Route of synthesis, Catalysis, Solvent/ Water, Reactor design, Batch
continuous
Recovery and recycle
Segregation of streams, Effluent treatment
Productivity & Process Intensification
Recovery
Waste Management
Slide7Action point 3
Managing effluents………. Shift from
end of pipe treatment to in-plant waste management
Can I segregate effluents ?
Good COD/ Bad COD
Can a chemical be recovered & recycled or sold?
Can the molecule/ process be replaced by green chemistry
What is the behaviour of molecule in aqueous environment
Slide8Action Point 4
Recovery of chemicals
Recovery Methodology
Understand Chemicals/ solvents and its composition
Based on the composition and market value of the product, target the recovery
Carry out trials- Technology customization
Reuse /sell the chemical
Sodium Sulphate
Sodium Carbonate
Potassium carbonates/ Chloride/ Nitrates
Adsorption using polymeric adsorbents –Separation of solvents/ metals/ chemicals
Slide9Action Point 5 Removal/treatment of recalcitrant chemicals……..
Use of efficient Reactors
Downflow
Gas Contactor
Condensates from MEE
Leachates from landfill site
Recalcitrant effluents
Can be used as pre-treatment/ tertiary treatment
Action Point -6 Capability Development programs for effective operation and maintenance
Slide11Wastewater management will be effective and sustainable only if …….
Every Industry organises its own house by measuring and monitoring water usage & wastewater generation
Continue to reduce water footprint….changing processes, water conservation
Enter into creative partnership with authorities , associations, educational institutes to develop cost effective solutions (transparency is the key).
Verbund
concept, common sludge management facility
Looking at supplies and purchase…. Green chemistry, coagulants, adsorbents
Innovations … technology, hardware
Enhance O&M and conduct capability development programs
What is the real issue?? Technology??
Hardware??
Or behaviour??
