GLDA: The High-Performance, Biodegradable Essential for Modern Water Treatment

In the rigorous landscape of European water treatment, the shift from traditional sequestering agents to eco-friendly alternatives is accelerating. Regulatory pressures from REACH and the EU Green Deal are pushing industries to phase out persistent chelates like EDTA and NTA.

At Yuanlian Chemical, we are leading this transition with our high-purity Tetrasodium Glutamate Diacetate (GLDA). Derived from natural, renewable plant-based materials, GLDA is the "green" chelating solution that meets the dual demands of industrial efficiency and environmental safety.

The Science of GLDA in Water Treatment

GLDA is a powerful, biodegradable chelating agent (sequestrant) designed to control metal ion activity in aqueous systems. Its molecular structure allows it to form stable, water-soluble complexes with hard water ions and heavy metals, even under challenging conditions.

1. Superior Scale Prevention

Unlike traditional phosphates, GLDA excels at sequestering calcium (Ca2+) and magnesium (Mg2+) ions across a wide pH range. This prevents the formation of scale in boilers, cooling towers, and membrane systems (RO/NF). By inhibiting mineral buildup, it maintains optimal heat transfer efficiency and significantly reduces energy consumption across the plant.

2. Heavy Metal Sequestration and Removal

For wastewater treatment and industrial process water, GLDA is a highly effective tool for managing toxic heavy metals. Its high binding affinity for Copper (Cu2+), Lead (Pb2+), and Zinc (Zn2+) allows for precise metal control, ensuring effluent meets strict European discharge standards without the persistence issues associated with older chemistries.

Why Yuanlian Chemical’s GLDA is the Industrial Gold Standard

As a primary manufacturer, Yuanlian Chemical ensures that our GLDA production meets the specific technical requirements of the European industrial sector.

• Exceptional Biodegradability: GLDA is classified as "readily biodegradable" (OECD 301B). It breaks down quickly in biological treatment plants, leaving no harmful residues—a critical advantage for facilities focused on ESG goals.

• High pH Stability: While many chelates lose effectiveness in extreme conditions, our GLDA remains stable and active in highly alkaline environments (up to pH 13). This makes it indispensable for industrial cleaning and CIP (Clean-in-Place) applications.

• High Solubility & Concentration: GLDA offers significantly higher solubility than traditional phosphonates or EDTA. This allows manufacturers to formulate more concentrated, cost-effective water treatment products, reducing shipping volumes and carbon footprints.

• Safe for Operators: It is non-sensitizing and has an excellent toxicological profile, ensuring a safer working environment compared to more corrosive or irritant alternatives.
