Applied Flocculation Efficiency: A Comparison of Polyethylene Oxide and Polyacrylamides.
Pap in Floc in Biotech and 1987 Sep; Amsterdam:175-185
This paper discusses some advantages and disadvantages of using polyethylene oxide (peo) polymers and acrylamide-based polymers as flocculants for a wide variety of mineral waste slurries. Peo is shown to be especially effective in wastes that contain a high percentage of clays or claylike materials. Conversely, in the absence of claylike materials, polyacrylamides are superior to peo. For those wastes that can be flocculated by either peo or polyacrylamide, peo generally requires a lower polymer dosage and yields more stable dewatered products. Differences in the behavior of these two flocculants are explained using proposed mechanisms.
