Crossflow Scrubber Tri-Mer Corp. Owosso, Mich.

The Tri-Mer Crossflow Series l/25 is engineered to scrub virtually all in- organic compounds. Dual-stage, high- speed liquid recirculation produces in- tense contact between the contaminant and scrubbing liquid and produces ex- tremely low stack emissions (below 80 ppb), regardless of input loading. Three system configurations are avail- able in capacities of 50 through 100,000 cfm, 50 through 50,000 cfm, and 120,000 cfm. Crossflow scrubbers are supplied with control panels, which incorporate flow meters, pH controls, flow indicators, ORP, alarms and aux- iliaries.
