Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1]
Michael Beach, a recreational waterborne illness specialist for the Centers for Disease Control and Prevention, stated in remarks to the Associated Press that wearing of nose clips to prevent insufflation of contaminated water would be effective protection against contracting PAM, noting that "You'd have to have water going way up in your nose ...
Successful treatment of PAM is rare; treatment can only be attempted after correct diagnosis, which relies on rapid recognition of the microorganism by medical technologists and pathologists. It is critical that medical technologists consistently provide timely CSF evaluation , explore the diagnosis of PAM, and look for amoebae in the setting ...
The water molecules must reorient around the nonpolar regions of PNIPA which results in a decreased entropy. At lower temperatures, such as room temperature, the negative enthalpy term ( Δ H {\displaystyle \Delta H} ) from hydrogen bonding effects dominates the Gibbs free energy , Δ G = Δ H − T Δ S {\displaystyle \Delta G=\Delta H-T\Delta ...
Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
