Ahlstrom Disruptor®

Improving Health - Protecting the Environment

Ahlstrom Disruptor® is an electrodsorptive technology for water purification and filtration

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

Disruptor® is specifically engineered to have this charge field cover 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 when compared to ultrafiltration membranes having similar efficiency.

Ahlstrom’s unique Disruptor® technology is creating many new application opportunities across the entire spectrum of water filtration. With the filtration efficiency of ultrafiltration membranes and the pressure drop of a 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.

With the ability to remove membrane biofoulants such as organic acids, bacteria and cellular debris Disruptor® is an effective pre-filter to protect 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.

Performance

Independent testing has shown Disruptor® to reduce 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 to effectively reduce low molecular weight organic acids and polysaccharides from fresh, brackish and salt water. These organic materials are now considered to be the main causes of fouling for hollow fiber and reverse osmosis membranes.
