ANIONIC EMULSION FLOCCULANT <br />DESCRIPTION <br />HYPERFLOC® AE 852 is a medium charge, <br />very high molecular weight anionic <br />polyacrylamide flocculent supplied as a low <br />viscosity emulsion. It is effective over the pH <br />range of 5 -12. <br />TYPICAL PROPERTIES <br />Appearance Opaque Liquid <br />Specific Gravity at 25°C 1.04 t 0.02 <br />Viscosty as supplied at 25°C 500 -1500 cps <br />Viscosity' (1% Solution) 1000-1400 cps <br />pH of 1.0% Solution at 25°C 7.0 t 1,0 <br />Freeze Point 5°F (-15°C) <br />Flash Point >200°F (93°C) <br />Shelf Life 8 Months <br />•erooknew ~vr, so rym at 2s•c ~, ae~avz°a water <br />APPLICATIONS <br />HYPERFLOC®AE 852 is used in a broad range <br />of solid-liquid separation processes in water <br />and waste treatment and mineral processing <br />applications for settling, thickening and <br />dewatering. It can be used alone or in <br />conjunction with alum or ferric salts, <br />poyaluminum chloride, polyamines and <br />polyDADMACs. <br />PREPARATION & FEEDING <br />Solutions of HYPERFLOC® AE 852 are <br />prepared by adding the neat polymer to water <br />below 120°F (50°C) either through an automatic <br />polymer feed unit or into the vortex of a stirred <br />tank of water to prepare a solution of 1 <br />concentration (as is). Aging for 30 - 80 minutes <br />is recommended, followed by in-line dilution to <br />0.1 % or less. Avoid excessive mixing as this <br />can Lead to polymer degradation. Use of gear <br />or positive displacement pumps is <br />recommended. <br />STORAGE & HANDLING <br />HYPERFLOC®AE 852 should be stored in a <br />heated building, 5° - 35°C (40° - 95°F). If <br />frozen, the product should be allowed to thaw <br />completely and agitated prior to use. Storage in <br />stainless steel, plastic or epoxy lined steel is <br />recommended. Mild steel, iron, aluminum or <br />mapper are to be avoided in both storage and <br />feed equipment. Bulk material should be mixed <br />every 1- 2 days using a low shear recirculating <br />pump, bottom to top. Mixers can be used n <br />drums or liqui-bins if necessary. Spills should <br />be wiped up with an absorbent material and <br />then washed down with a bleach solution. <br />Depending on the application, the following <br />dosage levels are recommended: <br />Water & Waste Treatment: <br />Setfiing/Clarificatton 0.5 to 20 ppm <br />ThickeninglDewatering 1.0 to 20 Ibs/ton <br />Minerals Processing: <br />Settling/Thickening 0.01 to 0.2 Ibs/ton <br />Dewatering 0.1 to 2 Ibsfton <br />03/02 <br />Toxicity is low, but normal precautionary <br />clothing should be wom when handling this <br />mater(al. For additional information, see <br />relevant Material Safety Data Sheet. <br />SHIPPING <br />HYPERFLOC®AE 852 is shipped in 55 gallon <br />non-retumabfe steel drums at 450 pounds net; <br />in non-returnable liqui-bins at 2300 pounds net; <br />or in bulk. <br />8/7/06 Addendum to Sediment Control System Page 5 <br />
