a factor of 2–3. This applies to both the anionic and non-ionic polyacrylamides, but residual levels from cationic polyacrylamides may be higher. Acrylamide was detected at levels of <5 µg/l in both river water and tap water in an area where polyacrylamides were used in the treatment of potable water. Samples

Chemical and Photolytic Degradation of Polyacrylamides Used

Polyacrylamides (PAMs) are a class of polymers formed from acrylamide alone or copolymerized with other monomers. PAMs have been used in drinking water treatment as flocculants or coagulants in the highest volume among all the polymer types. In potable water treatment processes, polyacrylamides are often exposed to oxidants (e.g. chlorine and

Using Polyacrylamide (PAM) to Reduce Erosion on Construction

One of the ingredients used to make PAM is acryamide, which is a suspected carcinogen, and as a result the PAMs available for our uses are required to have less than 0.05 percent free acryamide. This quality control allows them to be used in food processing, drinking water treatment, and other uses where human exposure is likely.

properties of polyacrylamides

Properties of Polyacrylamides

Cationic polyacrylamides (CPAM) are used for emulsion breaking, and for promoting filtration and sludge dewatering. The primary use is waste water treatment. As a primary organic coagulant, it neutralizes negatively charged colloidal particles and thus induces flocculation and sedimentation which reduces sludge volume.

Applications. Acrylamide is used as a monomer in the synthesis of polyacrylamides, which finds application as water-soluble thickeners in waste water treatment, gel electrophoresis, ore processing and dyes production. In molecular biology, it is used as a carrier as well as involved in the precipitation of small amounts of DNA.
