ANIONIC EMULSION FLOCCULANT <br />DESCRIPTION <br />HYPERFLOC® AE 852 is a medium charge, <br />very high molecular weight anionic <br />polyacrylamide flocculant supplied as a low <br />viscosity emulsion. It is effective over the pH <br />range of 5 -12. <br />TYPICAL PROPERTIES <br />Appearance <br />Opaque Liquid <br />Specific Gravity at 25°C <br />1.04:t 0.02 <br />Viscosity as supplied at 25°C <br />500 -1500 cps <br />Viscosity' (1 % Solution) <br />1000-1400 cps <br />pH of 1.0% Solution at 25°C <br />7.0 ±1.0 <br />Freeze Point <br />5°F (-15°C) <br />Flash Point <br />>200°F (93°C) <br />Shelf Life <br />6 Months <br />Brookfield LVr, 30 rpm at 25'C in doWked water <br />APPLICATIONS <br />HYPERFLOeAE 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 />polyaluminum chloride, polyamines and <br />polyDADMACs. <br />Depending on the application, the following <br />dosage levels are recommended: <br />Water & Waste Treatment: <br />Settling/Clarification 0.5 to 20 ppm <br />Thickening/Dewatering 1.0 to 20 lbs/ton <br />Minerals Processing: <br />Settling/Thickening 0.01 to 0.2 lbs/ton <br />Dewatering 0.1 to 2 lbs/ton <br />03/02 <br />Charlie Schulte <br />Tons Per Hour <br />PREPARATION & FEEDING <br />Solutions of HYPERFLOe 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 - 60 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, 50 - 35°C (400 - 950F). 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 />copper 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 in <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 />Toxicity is low, but normal precautionary <br />clothing should be wom when handling this <br />material. For additional information, see <br />relevant Material Safety Data Sheet. <br />SHIPPING <br />HYPERFLOC® AE 852 is shipped in 55 gallon <br />non -returnable steel drums at 450 pounds net; <br />in non -returnable liqui-bins at 2300 pounds net; <br />or in bulk. <br />
