  • What is polyacrylamide (PAM)?
  • PAM, or anionic Polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss.
  • How can a water soluble anionic polyacrylamide (PAM) reduce soil erosion?
  • Application of water-soluble anionic polyacrylamide (PAM) to the soil. Reduce soil erosion by water or wind. Improve soil surface infiltration rate and minimize soil crusting to allow for uniform plant growth. Irrigated lands susceptible to irrigation-induced erosion where the sodium adsorption ratio (SAR) of irrigation water is less than 15.
  • Is cationic polymer a polyaluminum chloride based Pam?
  • Their study used a cationic polymer from Calgon identified as Catfloc 2953 and was described as a polyaluminum chloride-based PAM. Tests of aquatic organism survival in treated runoff using daphnia in this series of studies showed no mortality under these conditions.
  • What is ionic polyacrylamide?
  • The ionic forms of polyacrylamide has found an important role in the potable water treatment industry. Trivalent metal salts, like ferric chloride and aluminum chloride, are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate.
