LV-22-C045 - Advanced Particle Removal Technology as an Efficient Tool for Addressing Emerging Global Air Quality and Safety Challenges

High-backpressure filters also use more energy and require frequent filter changes, making them more expensive to maintain and bad for the environment.This paper describes a new form of electrostatic filtration that is ideal for international markets since it has a uniform performance, low back pressure, is energy efficient, and can be tuned to perform at a range of filtration levels depending on demand. Developed at the University of Washington, the technology features porous electrodes that collect and hold a large capacity of particles regardless of their size and physical properties. This paper will describe the technology, prototype testing, including a 6-month pilot installation, and will detail how the technology can be used to achieve on-demand MERV 15 filtration levels in systems that require continuous low back pressure and reduced energy consumption.
