TripleClear Force Field TM
Filters
Submicron Depth Filtration Series The Triple Clear Force Field™ Submicron Depth Filtration Series uses a proprietary, patented, electroadsorptive media technology capable of removing submicron pathogens and inorganic contaminants through electro-adhesion and ion exchange. This technology makes it possible for a nonwoven media to produce filtration efficiency comparable to ultra membrane filtration, but at very low pressure drop. Force Field™ will work equally well in fresh, brackish, or salt water due to its high flow rates and high loading capacity. The media consists of coated micro-glass fibers produced using a wet laid nonwoven manufacturing technology. The base media is laminated between layers of spun-bond to provide both strength and pleat support. The media in the Force Field™ Filter is NSF 61-approved (Drinking Water System Components - Health Effects), and USP Class VI testing and endotoxin testing. The resulting filters have the ability to remove virus, bacteria, cyst, trace pharmaceuticals, heavy metals, RNA, DNA, VOC’s, organic acids, and cellular debris with almost no pressure drop, and no need for chemical treatment. Perfect for potable water applications, water re-use, reducing RO membrane biofouling, HVAC legionella protection, biofilm reduction, and securing the safety of stored water. Unlike any other filter on the market, Triple Clear’s Force Field TM Filters solve water challenges simply and effectively.

FIG.1: Shown above are three, 0.65 micron microglass fibers coated with alumina that form a pore approx 3 x 2 microns in size. Such a large pore allows for high flow rate at very low pressure drop but as a mechanical filter, has only about 2-3 micron initial efficiency. There are approximately 400 such pore structure layers in the Force Field TM Filter media to produce an excellent depth filtration media.
FIG. 2: When exposed to water between pH 5 – 9.5, a charge potential is generated by the natural crystal structure of the alumina fibers. The resulting charge field radiates to a maximum distance of 1-micron from the fibers as represented by the red shaded area. Expressed as streaming zeta potential, the charge field of Force Field TM Filters have been consistently measured as greater than 53 millivolts at pH 7.2.
FIG.3: Force Field™ has been specifically engineered to have an average pore size of 2 microns and a mean flow pore of 0.7 microns. This allows the charge field created by the alumina fibers to effect the total volume of the individual pores as well as virtually the entire void volume of the filter media itself! 1-micron Force Field TM Filter media has more than 400 individual pores making up the average sheet thickness of 0.8 mm. Contaminants are removed by being exposed to a torturous path through the media, depth and the powerful electropositive charge field generated by the alumina fibers.
FIGURES 1-3 above represent magnified views of the Force Field TM Filter media, and the processes of what takes place during the electrical charge created by the alumina fibers (from natural boehmite).
