Jiangsu Hengfeng has become a professional production and research and development base for water treatment chemicals and oilfield chemicals in China.

  • Application and function of polyacrylamide in Dissolved Air Flotation (DAF)

    Dissolved Air Flotation (DAF) is a water treatment technology used to remove pollutants such as suspended matter, grease, and solid particles from water. Flotation technology has a high removal efficiency for fine suspended matter and can remove tiny particles that are difficult to remove by traditional sedimentation methods. Flotation technology is widely used in the treatment of urban sewage and...

  • What are the protocols for dealing with spills or accidental releases of APAM in work environments?

    Anionic Polyacrylamide Powder (APAM) is widely used in industries such as oil recovery, wastewater treatment, mining, and papermaking, due to its highly effective properties as a flocculant and water treatment agent. Its ability to improve solid-liquid separation processes and enhance oil recovery has made it indispensable in modern industrial operations. However, as with any chemical substance, t...

  • How does a clay stabilizer chemically interact with clay particles to prevent swelling?

    A clay stabilizer plays an essential role in mitigating the challenges posed by water-sensitive clays in hydrocarbon reservoirs. When these clays come into contact with water-based working fluids—commonly used during drilling, fracturing, or other reservoir stimulation techniques—they tend to swell. This swelling occurs because certain clay minerals, such as smectite or montmorillonite, are prone ...
