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 andwall thickness using a Lecia dissecting microscope. From these measurements they were able tocalculate “hoop stress” of the fibers to determine the stress the fibers can withstand. Using theircalculations and the design characteristics of the way the fibers are used, Sawyer can confidentlystate that Sawyer fibers are 75% stronger than the other filter fibers that were tested. Thismeans the Sawyer fibers can be backwashed more vigorously, insuring longer life of the filter
