A Practitioner of Green Chemistry – Phosphorus‑Free Environmentally Friendly Water Treatment Chemicals

 With increasingly stringent environmental regulations worldwide and the push towards carbon peaking and carbon neutrality, the water treatment industry is undergoing a profound green transformation. Traditional phosphorus‑containing water treatment chemicals, although effective, can cause eutrophication and algal blooms when discharged. Finding highly efficient and environmentally friendly alternatives has become an inevitable trend.

Shandong Kairui Chemistry Co., Ltd. – a comprehensive, high‑end fine chemical enterprise integrating R&D, production, and sales – actively responds to the national “dual carbon” strategy and is dedicated to developing green, environmentally friendly water treatment chemicals. The company has a registered capital of RMB 128 million and is located in the Xuecheng Chemical Industrial Park in Zaozhuang, Shandong, occupying approximately 100 mu of land.

In the field of green water treatment agents, Kairui Chemistry has launched several phosphorus‑free, biodegradable products:

PASP (Polyaspartic Acid) is a water‑soluble polymer and a green water treatment agent, featuring phosphorus‑free, nitrogen‑free, and pollution‑free properties, and is fully biodegradable. It exhibits excellent scale inhibition and dispersion performance, making it an ideal environmentally friendly replacement for traditional phosphorus‑containing scale inhibitors.

PESA (Polyepoxysuccinic Acid) is another green water treatment agent with good biodegradability and outstanding scale‑inhibition properties.

KR‑928 Phosphorus‑Free Environmentally Friendly Scale Inhibitor is specially designed for low‑to‑medium hardness water. It achieves zero phosphorus discharge while maintaining excellent scale‑inhibition performance, making it particularly suitable for regions and industries with strict environmental requirements.

Furthermore, Kairui’s low‑molecular‑weight polyacrylate series, based on a unique low‑molecular‑chain structure, chelates scale‑forming ions in water through dual mechanisms of crystal distortion and electrostatic dispersion, fundamentally inhibiting pipe scaling. The products are phosphorus‑free, environmentally friendly, and readily biodegradable, with low dosage requirements and lower overall operating costs. They show good compatibility when combined with corrosion inhibitors and biocides.

Kairui Chemistry has built five specialised production workshops dedicated to organic phosphonates, polycarboxylate polymers, biocides, and other products, with a total annual capacity of 280,000 tonnes. The company employs advanced continuous production technology and a DCS automatic control system to ensure consistent product quality and stability.

Choosing Kairui Chemistry’s green water treatment agents means not only selecting highly efficient solutions, but also embracing responsibility for the environment. Let us join hands to contribute to the protection of blue skies and clear waters.

How can water treatment chemical manufacturers improve the transportation of water treatment chemicals?

 Most water treatment chemicals are liquids, so how can we transport them more effectively? Most manufacturers use plastic bottles for packaging. However, these chemicals are prone to leakage during transit, especially over long distances. How can we address this leakage issue? Here are a few suggestions for reference: First, focus on packaging selection. Opt for standardized plastic drums from reputable manufacturers with strict sealing standards. Currently, domestic plastic drum suppliers often mix batches, so procurement departments of water treatment chemical manufacturers must prioritize quality control in drum sourcing. Second, pay attention to packaging practices. Do not overfill containers. Even with sealed plastic drums, excessive filling can lead to leakage during transit due to impacts or compression. Leaked chemicals may contaminate other goods, causing unnecessary losses. Strictly adhere to standard packaging specifications during production. T...

The Ultimate Champion Among Chelating Agents! Why EDTMPA Surpasses EDTA as the Industry's New Choice

 The All-Rounder King Among Chelating Agents! Why EDTMPA Surpasses EDTA as a New Industry Choice In industrial production, the loss of control of metal ions often leads to a series of problems such as scaling, corrosion and product deterioration, so chelating agents have become "necessary products" in many industries. For a long time, traditional chelating agents such as EDTA and DTPA have dominated the market, but with the upgrading of industrial demand, Ethylene Diamine Tetra Methylene Phosphonic Acid (EDTMPA) has gradually surpassed traditional products with more excellent performance, becoming the "all-rounder king" in the field of chelating agents. The core competitiveness of EDTMPA comes from its super strong chelating ability. Scientific data show that its complexation constant with copper ions and other metal ions is much higher than that of EDTA and DTPA, which can lock metal ions more firmly and make them lose chemical activity. In scenarios such as water...
