Pool scrubbing and hydrodynamics in natural water, sea water and with additives

Pool scrubbing is an aerosol filtration system which consists in bubbling the gas flow through a pool of liquid in order to retain the aerosol in the liquid phase. Most pool scrubbing investigation dates back to 1980’s and 1990’s but the database allowed drawing some insights into pool scrubbing since there are still significant weaknesses: lack of systematic analysis of the parameters influencing pool scrubbing (i.e., submergence, particle size, etc.), no experimental tracking of variables like bubble size and shape. No less important, since the experimental programs were performed, some know-how has been lost throughout the years. Tests performed using the RSE SCRUPOS facility concerned both the study of hydrodynamics with measures of size, aspect ratio, bubble velocity in natural water, sea water and in the presence of additives and measures of aerosol retention in the same conditions.
