Chemical changes in the polymer are suspected as being responsible for the RSV change during the slow stage in the aging of the high intrinsic viscosity polyacrylamide and also in the aging of a polyacrylamide of low intrinsic viscosity.
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
operations use neutral (nonionic) or anionic flocculants. Nonionic flocculants are long chain poly-mers of polyacrylamides made from acrylamide mono-mer. Most flocculants used in aggregate applications are copolymers of acrylamide and sodium
Anionic and Nonionic Polyacrylamides - Kemira Anionic high molecular weight polymers are used for flocculating negatively charged particles by interaction with suitable cationic adsorption sites e.g. Ca 2+, Mg 2+, Al 3+, Fe 2+ and Fe 3+. Non

Top 10 Best Water Treatment Companies in The World. Following given is a list of the top 10 water treatment companies in 2025 which function with the sole aim of preserving water on the planet. the Japan-based manufacturers specialise in the designing and manufacturing of water treatment chemicals and facilities. With over 60 years of
We supply RO water makers that fully comply with the requirements applicable for the oil and gas industry. Supply of fresh water is an important issue in an offshore environment. Enwa’s systems using the reverse osmosis process will in most circumstances be the most efficient, economical and environmentally friendly process to secure that supply.
ENWA manufacture water treatment solutions to numerous sectors. We work closely with our customers; this enables us to provide efficient systems for specific water treatment needs. Our Maritime Oil and Gas division (MOG) provides a wide range of products and services. Production and design personnel work as integrated teams to ensure transparency.

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH2CHCONH2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N, N'-methylenebisacrylamide.
We started manufacturing the product in 2002 as the first manufacturer in Japan. Three grades are available – industrial, cosmetic and pharmaceutical – and they are used in a variety of applications which make use of its numerous functions, e.g. as a protective colloid, thickener and coating agent.
