GLDA: The Sustainable Revolution in Industrial Water Treatment

As European environmental regulations, such as REACH and the Water Framework Directive, become increasingly stringent, the industrial water treatment sector is undergoing a paradigm shift. The search for high-performance, readily biodegradable sequestering agents has led to the rise of Tetrasodium Glutamate Diacetate (GLDA).

At Yuanlian Chemical, we provide high-purity GLDA solutions that bridge the gap between powerful scale inhibition and ecological responsibility.

Why GLDA is Outperforming Traditional Chelators

For decades, EDTA was the industry standard. However, its inability to degrade in natural environments has made it a liability for European firms committed to ESG (Environmental, Social, and Governance) goals.

GLDA, derived from natural plant-based L-glutamic acid, offers a superior profile:

• Exceptional Biodegradability: GLDA is classified as "readily biodegradable" (OECD 301B), disappearing from wastewater systems far more efficiently than EDTA or phosphonates.

• High Solubility Across pH Levels: Unlike many chelators that struggle in acidic or highly alkaline environments, GLDA maintains high solubility and performance across a wide pH range ($pH2$ to $14$).

• Strong Chelating Power: It exhibits a high affinity for calcium, magnesium, and heavy metal ions, effectively preventing scale and corrosion.

Key Applications in the Water Treatment Sector

1. Industrial Boiler and Cooling Systems

Scale buildup ($CaC{O}^3$, $CaS{O}^4$) is the enemy of thermal efficiency. Yuanlian Chemical’s GLDA acts as a powerful descaling agent, sequestering hardness ions even at elevated temperatures. This ensures heat exchangers operate at peak performance, reducing energy consumption and carbon footprints.

2. Membrane Cleaning (Reverse Osmosis)

In RO systems, mineral scaling can permanently damage expensive membranes. GLDA is an ideal cleaning additive because it is gentle on the membrane material while being ruthless against metal-organic foulants.

3. Industrial & Institutional (I&I) Cleaning

For European laundry and dishwashing sectors, GLDA enhances the power of surfactants. It prevents the interference of hard water ions, ensuring that detergents work effectively even in regions with high mineral content, such as Southern or Central Europe.
