Presentation Transcript

Slide1

Sustainable Industrial waste water management

Jyoti Palekar - STEP Private Limited

Slide2

Effective performance and Sustainability of wastewater management Facility:

Optimum Design

Installation as per design

Receipt of waste as per design parameters

Effective and efficient operation

Slide3

Sustainability - What are the real Issues??

Slide4

Action 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

Slide5

Increased 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

Slide6

Action 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

Slide7

Action 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

Slide8

Action 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

Slide9

Action 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

Slide10

Action Point -6 Capability Development programs for effective operation and maintenance

Slide11

Wastewater 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??
