Is BCA similar to Electrostatic Precipitation (EP)?
Yes and No. Electrostatic precipitation is a novel purification technology that has attracted a niche following. These machines charge particles in a unipolar fashion (i.e. all the particles are charged in only one direction). The particles are then attracted to a grounding plate with the opposite polarity. Thus, the system looks like a sandwich with alternating charging electrodes and collection plates, with the fluid flowing between them, which requires frequent cleaning. BCA separates the fluid into two streams and charges particles in opposite directions, thus balancing the charge. Particles are mixed and are attracted to each other, growing in size. Once agglomerated, contaminants are easy to remove with ISOPur filter media.
