Taylor Color Card Comparator Test Kit, Polymer (free), Turbidimetric, 0-10 ppm
Polymers are widely used today in water treatment programs for both boiler and cooling systems. They are designed to work on hardness salts, iron, and suspended solids. These organic molecules act to increase the solubility of normal reaction products and to disperse solids so they do not accumulate on equipment surfaces. In boiler water the polymer treatment can be used alone or with other conditioners, like phosphates, phosphonates, and chelants. In cooling water the polymer is typically used in conjunction with corrosion inhibitors (such as orthophosphate or zinc) and/or scale inhibitors (such as phosphonates).
Polymer testing in boiler water is critical to the longterm performance of the program, especially when the polymer is used alone. Underdosing allows scale to form. Severely underdosing the polymer in relation to the hardness in the water can lead to calcium polyacrylate scaling. Overdosing not only incurs unwarranted chemical costs, but also can increase corrosion in the boiler system. Moreover, since polymers are organic, they are susceptible to thermal degradation at high cycles of concentration (over 50 cycles). For all these reasons the active polymer concentration should be tested regularly.
Taylor’s polymer test employs a simple turbidimetric method. First, turbidity is filtered out of the sample water with the syringe filter included in the kit. When reagents are then added to the prepared sample, turbidity develops in proportion to the amount of polymer in the water. The degree of turbidity observed after a timed five-minute wait is compared to a set of printed standards and their interpolated values. (See instruction on reverse.) The closest match indicates the concentration in parts per million polyacrylic acid. Interferences listed in the note below should be considered when running this test.
Note: All polymer test apparatus should be disassembled and thoroughly rinsed with distilled, deionized, or tap water between tests.
