Polyacrylamide (PAM) is a very important water-soluble polymer, which is used as a thickener or modifier in the formulations of tertiary oil recovery, drilling fluid, hydraulic fracturing, drag reduction, wastewater treatment [], paper-making,
- What is Pam chemical used for?
- It can enhance flocculation, reduce the cost of clean water, improve water quality, and remove organic matter and algae in the water. PAM chemical has a wide range of applications in water treatment, petroleum exploration, textile, papermaking, mineral processing, medicine, agriculture and other industrial fields.
- What is Pam used for in industrial water treatment?
- In industrial water treatment, PAM can be used for scale inhibition and corrosion inhibition, helping to maintain the proper functioning of equipment. It can also be employed in the maintenance of cooling water systems, reducing corrosion and microbial growth while enhancing system efficiency.
- What is Pam water purification & how does it work?
- In the process of purifying drinking water, PAM serves as a purification agent, aiding in the removal of suspended solids, organic matter, and color from water. It enhances filtration efficiency, ensuring safe and hygienic drinking water.
- What are the top brands of water treatment chemicals?
- Significant brands include Aquaflex, MicroGuard, Pentek, Seaflex, Seaguard, and X-Flow membrane equipment; and American Plumber filtration equipment. SNF was the top manufacturer of water treatment chemicals for the global market in 2018, per Freedonia data.
