Technical Data Sheet 1 (2) 9.4.2014 Superfloc® SD-2091 Cationic Emulsion PAM Superfloc SD-2091 is a unique cationic emulsion. The charge range and molecular structure is specifically developed for use in sludge conditioning, wastewater treatment and water clarification processes across a wide variety of industries. Superfloc SD-2091 is especially suited for biological and higher ash content sludges where increased cake solids are needed. Applications Superfloc SD-2091 is recommended for the following liquid-solid separation processes: Belt filter, screw press and centrifuge dewatering – increase production rate, cake solids and solids capture Dissolved air flotation Coagulant aid – settling aid with inorganic and organic coagulants Water clarification – improve influent, process and effluent water quality by reducing suspended solids and turbidity Thickening – improve compaction, settling, drainage and effluent quality. Delivery Superfloc SD-2091 is available in different pack sizes. Please contact your Kemira sales representative for more information. Benefits Economical to use – effective at low dosage levels Achieve high solids removal efficiencies Easily soluble in water; dissolves rapidly Liquid form for easier handling Exceptionally high molecular weight and broad cationic range Product Properties Chemical Type Cationic Polyacrylamide Appearance Opaque Liquid Viscosity 500 – 1500 Solids 45 – 55 Insolubles <0.5% Res’d AMD <1000ppm *This does not constitute a specification Product Safety For specific handling information, please refer to the current Material Safety Data Sheet, which is available upon request.

Prior to initial use, Superfloc SD-2091 should be agitated thoroughly via a low speed (<475 rpm) drum/IBC mixer or a recirculation pump to ensure uniformity. Recommended working solutions are 0.5% concentration; however, stock solutions can be prepared up to 1% via an automated make-up unit or on a batch basis. Solutions should be aged 30 minutes for maximum effectiveness. High quality make up water should be used. Secondary dilution water can be added to the stock solution prior to the addition point to improve mixing with the substrate at a ratio up to 10:1. A distributing header or distribution ring is recommended in the treatment stream. Avoid centrifugal pumps for polymer transfer. Recommended materials of construction include fibreglass reinforced plastic (FRP), high-density and/or cross linked polyethylene, glass or epoxy-lined vessels. Stainless steel (316L) is recommended for interim storage of neat polymer. Depending on environmental conditions and the length of time, corrosion of stainless steel is possible. Stainless steels, Teflon, various plastics and rubbers are acceptable for pumps, seals and feed lines for both neat products and product solutions. Avoid natural rubber and Buna-N gasket as these tend to swell when placed in contact with neat polymer. Do not use iron, copper aluminium or brass. The shelf life of this product is 6 months when stored at temperatures between 5 and 30°C. For best results avoid freezing. If the product freezes, thaw completely and mix prior to use. It is recommended that bulk tanks are mixed by periodically recirculating the contents of the tank. If possible, drums and totes should be mixed well before first use and periodically thereafter. Spilled polymer is very slippery and should be absorbed onto an inert material and collected prior to thoroughly flushing with water.
