Liquid Polymer Systems are used to activate and dose polyacrylimide solutions. There are several types of polymers and those types influence the type of equipment you will require. Solution Polymers These are the easiest of the polymer family to deal with. The product is a true solution of actives and water and requires only to be metered into the process in the right concentration. Many solution polymers are used as coagulants for dewatering processes in waste treatment, mining and pulp and paper. Emulsion Polymers This type of polymer is encapsulated in latex to keep the product inert. To use the product in your process it will need to be inverted or released from the latex shell. Many types of proprietary means are available to cause the inversion. Mechanical or hydraulic shear is the usual means. This type of polymer requires more care and control in handling but is available for a variety of processes including dewatering, retention aid, Alumina refinery, and waste stream conditioning. Liquid Polymer Equipment We like to talk about two categories of equipment, utility and high end. The difference is in how you use polymer in your process. If you are a dairy and use polymers for waste treatment in your Dissolved Air Floatation system. You are typically looking for less expensive equipment without all the bells and whistles. This is our utility concept. If polymer usage is critical to your process like a paper mill or an alumina refinery, then you require our high end systems. These systems provide measurement of critical variables, high quality components and redundancy. High End Polymer Preparation System Your best options when polymer is critical to your process is a system that measures the variables of make down and adjusts automatically. Further to making sure that nothing can cause interruptions to the make down process redundancy of key components is critical. How does Chem-Flow build its Polymer make down and feed systems to deal with the needs of your critical polymer application? Our Polyprep feeder is the only commercially available standard unit that provides fully redundant polymer metering pumps. Additionally our control strategy provides logic that if the flow rate drops below the required amount, the second pump will automatically start up and raise an alarm. This means that solution production continues while letting your staff know that there is a problem.
