Features of Ahlstrom Disruptor® PAC media

• Has similar particulate retention, flow and pressure drop as media without PAC

• Disruptor® PAC has a median particle size of ~8 micron (90% less than 625 mesh) producing rapid adsorption kinetics due to high surface to volume ratio of the carbon

• Small particles of PAC are retained by electro adhesion, not mechanical retention or through the use of binder fibers or chemical additives

• Improves taste, odor, clarity and safety of potable water

• Reduces chlorine, endocrine inhibitors, ibuprofen, trace hydrocarbon, bacteria, viruses, cysts and natural organic material (NOM)

• Mean PAC particle size ~ 8 micron

• Small particle size produces rapid reaction with contaminants

• No adhesives used to retain the PAC

• Total PAC pore space available for reaction

• The carbon in Disruptor® PAC media is inherent to the active layer

• The media is laminated between two layers of spun bond polypropylene for strength and pleat support

Disruptor 2194-327 (PAC) media. Input free chlorine concentration 2 ppm

Filtered 17,000 liters of water w/ input conc. of 2.25 ppm, output conc. of 1.01 ppm. Corresponds to adsorption of ~23 g of free Cl by 24 g of PAC. On absorption of 958 mg of free Cl per 1 g of PAC. Simulation of EPA protocol for Cl removal from drinking water with stagnation points.

Data Ahlstrom Filtration LLC

Cartridges made with PAC media have been shown to have a chlorine reduction capacity of over 4500 gallons

• It is important to note the distinction between nanosilver and the silver impregnate zeolite we use in Disruptor® products

• Nanosilver is typically 25 nanometers in size and can freely move through the dermal layer and in between human cells

• The Agion® silver impregnated zeolite we use has an average diameter of 2 micron (2000 nanometers) or approximately 100 times larger than nanosilver

• This difference in size eliminates the possibility of the Agion® zeolite being considered to be nanoparticle. In addition, the Agion® product contains the silver internal to the zeolite. Silver is not available in a free form.

• This means the silver contained within the zeolite can only be released in the presence of other ions, taking the place of the silver in the zeolite. This method of ion exchange provides for controlled delivery.

Silver Antimicrobial: important to note
