Kerui Chemical High‑Efficiency Decolorant – Solving Decolorization Problems in Printing & Dyeing and Papermaking Wastewater

 Wastewater from printing & dyeing, papermaking, and leather industries has high color intensity and complex composition. Conventional flocculation/sedimentation often fails to meet discharge standards. Decolorants separate chromophores from water through adsorption, complexation, and charge neutralization.

Kerui Chemical (krhedp.com) provides dicyandiamide‑type and modified organosilicon high‑efficiency decolorants:

  • Dicyandiamide‑type decolorant: Over 98% decolorization for reactive dyes, acid dyes, and direct dyes, while significantly reducing COD and suspended solids.

  • Modified organosilicon type: Suitable for high‑concentration, refractory wastewater; combines demulsification and flocculation, especially for emulsified dye wastewater.

  • Usage tips: Adjust pH to 6–9 first; dosage 50–300 ppm depending on raw water color; works best with PAC/PAM.

Customer feedback: After using Kerui Chemical decolorant, a printing plant in Guangdong reduced effluent color from 500× to below 20×, stably meeting the “Discharge Standard of Water Pollutants for Textile Dyeing and Finishing Industry.” Apply for a free sample at krhedp.com or contact customer service.

Phosphorous Acid: A Chemical Raw Material with Both Reactivity and Value

 In the field of inorganic chemicals, phosphorous acid (H₃PO₃) is an important compound with unique chemical reactivity and extensive application value. Although its name is similar to phosphoric acid, their properties are significantly different. This dibasic medium-strong acid plays an indispensable role in industrial production and scientific research. In terms of basic properties, phosphorous acid appears as white or light yellow crystalline powder at room temperature, with a special garlic-like odor, a characteristic that makes it easy to identify. It has good solubility, being not only highly soluble in water but also miscible with organic solvents such as ethanol. It oxidizes slowly to phosphoric acid when exposed to air, so it should be stored in a sealed container to prevent moisture absorption. The core of its chemical properties is strong reducibility; it can react with various oxidizing agents such as silver ions, halogens, and hydrogen peroxide. For example, it can red...
