Disruptor® water filtration technology was first introduced over a decade ago as a new innovation utilizing fibers and charge to achieve 4 log reduction of virus in gravity flow and pressurized water applications. Numerous studies have been conducted to establish multiple contaminant removal capabilities of standard Disruptor®. These have increased the understanding of Disruptor®’s ability to remove E. coli bacteria, legionella bacteria, endotoxin, humic acid, Iron (II & III), and trace pharmaceuticals (PCBs). What started as a defined and limited technology continues to evolve into a versatile product line able to meet today’s challenges within the water filtration industry.
While Disruptor® has proven its viability on the market for the past decade, recent developments and industry preferences have seen the technology enter a new phase of enhanced development. This includes expansion of filtration capabilities accomplished by introducing functionalized additives that have a synergistic effect when used in conjunction with traditional Disruptor® technology. Disruptor® technology utilizing these functionalized additives provides the biological removal efficiencies known to be achieved by Disruptor®, while also providing enhanced removal of chemical contaminants such as chlorine, chloramines, soluble and insoluble lead, arsenic, and select species of PFAS. Removal efficiency data and capacity curves are used to validate performance criteria.
Increased demand for higher flow material for use in gravity flow applications has led to the creation of a more open media that takes advantage of functionalized additives in order to retain high efficiency virus removal with a larger pore structure. This particular functionalized additive has also led to the development of a compostable prefilter that will not require lamination due to its high mechanical strength and pleatability. A growing social and commercial demand for sustainable products has been a driving force in this recent innovation.
With newly emerging contaminants creating concern for consumers, Disruptor® has proven to be an adaptable technology capable of meeting ever-changing market demands. These developments are focused on the ability to provide water filtration solutions based upon traditional Disruptor® technology, now including synergistic functionalized additive options in both Disruptor® filtration media and pre/post filters.
