EDTA and NTA Salts for Water Treatment in Gujarat

EDTA (Ethylenediaminetetraacetic Acid) and NTA(Nitrilotriacetic Acid) salts are widely used chelating agents in water treatment processes. They bind with metal ions like calcium, magnesium, iron, and heavy metals, helping prevent scale formation, corrosion, and metal contamination in industrial and municipal water systems. These salts are crucial for improving water quality, efficiency of boilers, cooling towers, and effluent treatment systems.

In Gujarat — a hub for chemical, textile, pharmaceutical,and manufacturing industries — demand for high-purity EDTA and NTA salts is strong due to their eco-friendly properties, efficiency, and regulatory compliance in water purification.

What Are EDTA and NTA Salts?

EDTA Salt Forms: EDTA Disodium, EDTA Tetrasodium, EDTA Acid
NTA Salt Forms: NTA Trisodium, NTA Acid
Both are biodegradable complexing agents that improve metal ion solubility and prevent precipitation.

Applications of EDTA and NTA Salts in Water Treatment

Boiler and Cooling Tower Water Treatment – Prevents scale and corrosion
Industrial Wastewater Treatment – Removes heavy metal ions (Pb, Cu, Zn)
Municipal Water Purification Plants – Reduces metal hardness and fouling
Reverse Osmosis (RO) Pre-treatment – Enhances membrane life
Effluent Treatment Plants (ETP/STP) – Improves sludge conditioning
Textile Dyeing & Processing Units – Prevents metal interference in dyeing
Paper & Pulp Processing Water Systems – Controls deposition of metal oxides
Chemical Blending & Formulation – Ingredient in detergents and cleaners
Food-Grade Applications (with purity grade) – Preservative or stabilizer (EDTA only)
Pharmaceutical Water Systems – For precise pH control and impurity removal

Top 10 FAQs – EDTA & NTA Salts for Water Treatment

What is the role of EDTA and NTA in water treatment?
They chelate (bind) metal ions to prevent scaling, corrosion, and water contamination.
What is the difference between EDTA and NTA salts?
EDTA is more stable and widely used; NTA is more biodegradable and eco-friendly.
Which salt form is best for boiler water treatment?
EDTA Tetrasodium or NTA Trisodium is preferred for their high solubility and alkalinity.
Are these salts safe for the environment?
Yes. Especially NTA, which is readily biodegradable and less toxic.
Can EDTA be used in food or pharma applications?
Yes, food/pharma-grade EDTA is used as a stabilizer and preservative.
Do these salts affect water pH?
They can influence pH depending on salt type. Tetrasodium raises pH; Disodium is closer to neutral.
Is EDTA suitable for RO plants?
Yes, it helps reduce fouling by binding calcium and iron before water reaches RO membranes.
How are these salts added to water systems?
Typically dissolved in dosing tanks and injected via metering pumps.
Can both be used together?
Yes, but usually only one is needed based on performance, cost, and environmental goals.
What is the price of EDTA and NTA salts in Gujarat?
?80–?180/kg for EDTA salts and ?70–?150/kg for NTA salts (based on purity & packaging).
