“The Science of Polymer Activation”
Lashley Loomis
Despite the wide‐spread use of polymers in water and wastewater and their high recurring expense, there are very limited technical resources readily available to the many interested engineers and operators. With many  equipment options available to operators, it makes sense to start with the basics of polymer chemistry. This  discussion will review the basics of polymer chemistry, goals of activation, the development of polymer mixing  equipment and equipment configuration basics.  Factors such as charge site exposure, application of mixing energy and the effects of dilution water will be  detailed as they influence proper polymer activation. Additionally, the impact of water quality attributes on  polymer hydration are explored, and finally, the benefits of utilizing two‐stage – very high initial mixing energy  followed by low and uniform mixing energy – is determined by theoretical consideration and practical test data.  Lastly, Polyblend systems which have been leading the industry for thirty years are discussed as well as the most  recent breakthroughs in mix chamber sizing that improves residence time to achieve optimal solution viscosity.
