This paper investigates the use of wet electrostatic scrubbing as a way to remove bacterial bioaerosol from air. This process is based on the electrical interactions between naturally or artificially charged bacteria and charged droplets. Two configurations were explored: CDES (Charged Droplet Electrified Scrubber) and OPES (Opposite Polarity Electrified Scrubber). Tests were performed with Staphylococcus epidermidis, a common bacterium of human skin flora. The process successfully remove the bioaerosol. When operated as a CDES, the removal efficiency is >90% by operating with a liquid-to-gas ratio of 2.4 L m−3 gas. The OPES efficiency is >99% when the liquid-to-gas ratio is > 0.8 L m−3 gas

Abstract
This paper investigates the use of wet electrostatic scrubbing as a way to remove bacterial bioaerosol from air. This process is based on the electrical interactions between naturally or artificially charged bacteria and charged droplets. Two configurations were explored: CDES (Charged Droplet Electrified Scrubber) and OPES (Opposite Polarity Electrified Scrubber). Tests were performed with Staphylococcus epidermidis, a common bacterium of human skin flora. The process successfully remove the bioaerosol. When operated as a CDES, the removal efficiency is >90% by operating with a liquid-to-gas ratio of 2.4 L m−3 gas. The OPES efficiency is >99% when the liquid-to-gas ratio is > 0.8 L m−3 gasI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
