TDS vs Conductivity — Understanding the Difference

 TDS vs Conductivity — Understanding the Difference 

PART 2: 

Did you know that TDS and conductivity are related, but they are not the same measurement? Both are important indicators used to monitor water quality and the performance of water-treatment systems.

In Part 2 of our AquaTradeHub Water Treatment Education Series, let’s explore the key differences.

💧 1. What Is TDS?

TDS (Total Dissolved Solids) estimates the concentration of dissolved substances in water, including dissolved salts and other inorganic and organic matter.

📌 Common units: mg/L or ppm

⚡ 2. What Is Conductivity?

Conductivity measures water’s ability to conduct electrical current, primarily due to dissolved ions such as calcium, magnesium, sodium, chloride, and sulfate.

📌 Common units: µS/cm or mS/cm

📊 3. Key Differences

🔹 TDS: Expresses dissolved-solids concentration, usually as an estimated or analytically determined value.

🔹 Conductivity: Indicates how readily water conducts electricity due to dissolved ions.

🔹 Relationship: Conductivity often increases as dissolved ionic content increases, but the relationship depends on the water's chemical composition.

🔄 4. Useful Unit Conversion

✅ 1 mS/cm = 1,000 µS/cm

Remember: this converts conductivity units, not conductivity into TDS.

🧮 5. Estimating TDS

TDS (mg/L) ≈ Conductivity (µS/cm) × TDS Factor

A factor such as 0.65 may be used for an illustrative estimate, but the correct factor depends on the water composition and should be validated for the application.

⚠️ Important Note: Conductivity-based TDS readings are estimates, not universal conversions. For critical water-quality decisions, use an appropriate validated method.

The High-Level Roundtable on India–South Africa Cooperation for a Just Transition and Green Industrialization, held on 12 October 2026 at Development Alternatives Headquarters, New Delhi, brought together policymakers, industry representatives, academia and civil society to explore pathways for just energy transition.

 The High-Level Roundtable on India–South Africa Cooperation for a Just Transition and Green Industrialization, held on 12 October 2026 at Development Alternatives Headquarters, New Delhi, brought together policymakers, industry representatives, academia and civil society to explore pathways for just energy transition.

Marking the launch of the JUST SA International Study Tour, the roundtable focused on strengthening cooperation and knowledge exchange between India and South Africa, aligning decarbonisation with energy security, economic development and inclusion.

Representing Greenko, Dr. Paravastu Rambabu, Senior Leader, shared Greenko’s perspective on the evolving clean energy landscape, highlighting the critical role of energy storage in delivering firm and despatchable power that is affordable and green fuels, chemicals and metals in advancing the energy transition and catalysing industrial growth.

The dialogue explored workforce skilling, community participation and transition finance, underscoring the importance of ensuring that the transition creates meaningful opportunities for workers, communities and industries.

As India advances towards its net-zero ambitions, Greenko remains committed to delivering integrated energy transition solutions that enable sustainable industrial growth while strengthening the nation’s energy security and social inclusion

The core framework centers around 10 core sustainability focus pillars / missions: 

1. Climate & Energy
2. Water Stewardship
3. Biodiversity & Ecological Restoration
4. Waste Management & Circular Economy
5. Diversity, Inclusion, Respect & Equity (DIRE)
6. Stakeholder & Community Engagement
7. Capability Enhancement & Education
8. Occupational Health and Safety
9. Innovation & Operational Excellence
10. Ethical Governance & Sustainable Finance
