Abstract

Scrubbing system for treating malodorous air comprised of two or more stages. In the first stage, the air is passed through a first packed scrubber tower (12) and is scrubbed with a countercurrent flow of a scrubbing solution containing the oxidant sodium hypochlorite (NaOCl). The sodium hypochlorite is produced by passing a salt brine (NaCl) through electrochemical cells (14). In the second stage, the air passes through a scrubbing chamber (26) and then a second scrubbing tower (24). A second scrubbing solution contacts the air in the scrubbing chamber (26) and is collected in the bottom duct (30) connecting the scrubbing chamber (26) and the second scrubbing tower (24). The second scrubbing solution is then recirculated to the top of the second scrubber tower (24). Caustic is added, continuously or intermittently, depending on the make-up of the air, to the second scrubbing solution before it is used in the second scrubbing tower (24).
