Improving health and protecting the environment

Ahlstrom-Munksjö's Disruptor® is an electrodsorptive technology for water purification and filtration

Disruptor® filter media remove a wide range of submicron particulates, pathogens, trace pharmaceuticals and cellular debris with a naturally occurring electropositive charge.

Disruptor® is specifically engineered so the charge field covers the entire depth and void volume of the media. By accomplishing submicron "filtration" with a charge field rather than with mechanical pores, Disruptor® has a small fraction of the pressure drop and many times the flow rate, compared to ultrafiltration membranes with similar efficiency.

Ahlstrom-Munksjö’s unique Disruptor® technology creates many new application opportunities across the entire spectrum of water filtration. With the filtration efficiency of ultrafiltration membranes and the pressure drop of 2 micron nonwoven media, Disruptor® can be considered as an alternative for membranes in many residential and commercial applications. These include point-of-entry and point-of-use devices, such as: whole house filters; countertop, tap and under-counter filters; water dispenser ice machines; food and beverage preparation etc.

With the ability to remove membrane biofoulants, such as organic acids, bacteria and cellular debris, Disruptor® is an effective pre-filter for protecting reverse osmosis membranes from biofouling. By reducing membrane biofouling, Disruptor® extends the performance and life of RO membranes by increasing the time between clean-in-place treatment, and reduces the volume of reject water.


Independent testing has shown that Disruptor® reduces the MS2 virus at greater than 99.99%. It can remove a wide range of bacteria at greater than 99.9999%, including E. coli, Pseudomonas and Legionella. Removal of 3-micron spheres (as a surrogate for cryptosporidium) is greater than 99.95% efficiency. Disruptor® has been proven to remove certain species of colloidal metals, hazardous compounds, such as PCB’s, and trace pharmaceuticals, including BPH, a known hormone inhibitor.

Independent university testing has shown Disruptor’s combination of electroadsorption and depth filtration effectively reduces low molecular weight organic acids and polysaccharides from fresh, brackish and salt water. These organic materials are considered to be the main causes of fouling for hollow fiber and reverse osmosis membranes.
