Dynablend Brochure

polymer BlendingKnowing the critical requirements of polymer blending is the first step inunderstanding the numerous benefits of dynaBLEND® technology. Over the years, the spectrum of available polymers has widened. Today there aremore difficult-to-blend polymers than ever before. Some polymer blendingsystems work well on simple-to-blend polymers, but fail to effectivelyactivate many other polymers.As-supplied or Concentrated Polymer—Polymer is a long chainmolecule having positive (cationic), negative (anionic) or neutral (non-ionic) charge sites. In its as-supplied, concentrated form, thepolymer is tightly coiled. In this state, the polymer is not susceptibleto damage from high mixing energy.Effects of Insufficient Mixing Energy—When insufficientmixing energy is applied, polymer gelling or agglomerationoccurs, resulting in the charge sites not being fully exposed.Overdosing of polymer is required to achieve desired performance.Effects of Overexposure to Mixing Energy—Overexposingpolymer to mixing energy after initial activation will damage the fragile long chain molecule. Again, overdosing of polymer is required.Fully Activated Polymer—Unwinding and elongating the coiledpolymer molecule is necessary to expose the maximum number ofcharge sites to your process. The job of the polymer activation andblending system is to gently and thoroughly activate polymer. Fullyelongated, undamaged polymer is the most active and effectiveform yet also the most fragile state. Continued exposure tomixing energy in this state will damage the fragile polymer.the way to Optimum polymer performance1. "Infinite Shear in Zero Time." Apply ultra-high mixing energy at the point of initial polymer and water contact to prevent polymer gellingor agglomeration. At this time the polymer is coiled-up and notsusceptible to damage.2. Create the right environment. Polymer solution has proven to be theideal environment for polymer activation, as opposed to raw water. Injectneat, concentrated polymer into polymer solution, not raw water.3. Prolonged turbulence. Expose polymer to prolonged turbulence inorder to complete the blending process gently and fully. 4. Avoid damaging mixing energy after the polymer is initially activatedso as not to break the fragile molecular chain.our HistoryRight from the start . . . In 1985 Fluid Dynamics developedthe high energy, non-mechanicaldynaBLEND® liquid polymeractivation and blending technology.Immediately it proved to be arevolutionary and great improve-ment in polymer activation andblending performance. Today, thedynaBLEND® system remains the most effective and reliable polymer activation technology—rendering mechanical blenders obsolete except for low flow applications.2Consider your investment—whetherit be a centrifuge, belt filter press,clarifier, filter, paper machine, orwhatever your process requires, your investment is substantial.Doesn’t it make sense to protect this investment?A polymer blending and activation system can dramatically affect the performance and reliability of this process.You Should Expect:?

Total Satisfaction Guarantee* See Fluid Dynamics warranty for further details.the Choice is clear3proven PerformanceWhile some polymer systems can only work well on the simple-to-blendpolymers, dynaBLEND® has a proven track record of effectively activatingall types of polymer. dynaBLEND is the standard for manufacturers of ultra-high molecular weight and high solids type polymers.proven ReliabilitydynaBLEND is designed for reliability. The non-mechanical dynaBLEND mixing chamber design inherently delivers an unequalled degree of reliability over many mechanical technologies. But we don’t stop there. The polymer injection check valve is a potential maintenance issue in any polymer system. Fluid Dynamicsdesigned the PCV valve, a large port check valve with spring-loadedstainless steel ball and Teflon® body. The PCV valve easily disassembles forinspection or cleaning simply by pulling a two-prong stainless steel pin.proven QualityHighest Quality = Lowest Life Cycle Cost dynaBLEND is thebenchmark for quality in our industry. Why? Because of the value oflongevity. dynaBLEND quality is achieved by building a more rugged system with higher quality components and tight quality control using highly skilled people.With quality comes confidence. dynaBLEND is backed by the longestwarranty in our industry—two (2) year system warranty and lifetime mixingchamber warranty.4simply the Best polymer system availabledynaBLEND® L Series systems are designed to easily accept a wide range of flexible features and options.

Success is due to its patented, non-mechanical HydroAction Technology—a technology that produces in excess of six times the mixing energy per unit volume than a comparable-sized mechanical mixer.initial ultra-High energyA pressure drop occurring across thespecially designed variable orifice watercontrol valve produces a high velocitywater jet. This water jet, traveling atapproximately 70 ft. per second, isaimed directly at, and impinges on thepolymer as it enters the mixing chamber.At this point, the only point where high energy exists in the mixing chamber, the polymer is coiled-up and not susceptible to damage.reCirculationIn dynaBLEND’s concentric mixingchambers, newly blended polymerrecirculates multiple times for additional exposure to non-damagingturbulence, completing the blendingprocess. This recirculation ensures thatpolymer solution is present directly afterthe point of neat, concentrated polymerinjection, for an ideal activation andblending environment.diminishing mixingEnergyMixing energy naturally diminishes in dynaBLEND’s concentric chambers.The flow path through the system’sconcentric chambers further ensuresoptimum polymer performance bypreventing polymer from short-circuitingthe three stage process.dynaBLEND induces highmixing energy without the useof mechanical impellers toensure a blending process freefrom polymer damage, whilepreventing polymer gelling.Preventing polymer gelling or damage maximizes yourpolymer investment by reducingyour polymer use. Thousands of installations worldwidevalidate dynaBLEND’s trackrecord for superior performance and reliability.5series L4-D / L6-D specificationsThe L4-D / L6-D SeriesdynaBLEND® is a full featuredliquid polymer blending system.These are the smallestdynaBLEND units and the useof a diaphragm pump makesthem the most economicalpolymer blending systemoffered by Fluid Dynamics.WATER SUPPLY PRESSUREWater supply must be able toprovide the maximum flow rate at 35-50 psi (240-345 kPa)greater than the pressure atpoint of use.OPERATING PRESSURE100 psi maximum (689 kPa)DIMENSIONS24" D x 24" W x 68" H(61cm x 61cm x 173cm)WEIGHTSeries L4-D: 175 lbs.
