Depth Filters

Suez Water Technologies’ one-step manufacturing process continuously extrudes and thermally bonds pure polypropylene microfibers into a complex filter matrix. Microfilaments combined with precise control maximize the positive filtration characteristics of graded density, tight micron cutoffs and maximum void area with millions of tortuous paths. This fully automated manufacturing process assures consistent quality, filter to filter, year in and year out. Thermal and vacuum finishing procedures produce exceptionally clean filters imprinted for easy identification in the field.
