Prueba de resistencia del filtro de fibra hueca Sawyer

Calvin College conducted a study on the fibers used in various brands of Hollow FiberMembrane water filters. They carefully dissected the filters to measure the fiber diameters and wall thickness using a Lecia dissecting microscope. From these measurements they were able to calculate “hoop stress” of the fibers to determine the stress the fibers can withstand. Using their calculations and the design characteristics of the way the fibers are used, Sawyer can confidently state that Sawyer fibers are 75% stronger than the other filter fibers that were tested. This means the Sawyer fibers can be backwashed more vigorously, insuring longer life of the filter
