WHATS THAT AWFUL SMELL € Nearly all manholes and vent stacks suffer with odor problems, whether they are around restaurants, commercial buildings, small lift stations or EQ tanks. The main culprit is hydrogen sulfide (H2S), but other malodorous compounds are present, as well. The problem has largely been treated with the activated carbon. PEC Sweetfilter II Commercial Manhole and Vent Filters use the same patented technology found in PEC Sweetfilters Proven, practical technology which destroys odors *- and lasts. A SENSIBLE SOLUTION FOR COMMERCIAL ODOR CONTROL The Sweetfilter II design provides generous venting through the patented oxidizing/polishing media. Oxidation is accomplished with chlorine dioxide technology. Because chlorine dioxide reacts selectively and primarily with only the most offensive odor producing compounds (hydrogen sulfide, organic sulfurs, organic amines) will normally provide a longer service life in commercial application than activated carbon while addressing a similar broad-spectrum malodor control. Chlorine dioxide remains available and ready on demand. Polishing is accomplished with technology that protects against the escape of malodors which can not be oxidized or readily oxidized. It incorporates polymeric adsorption and electrostatic bonding technologies. Polishing and oxidizing are accomplished simultaneously. The result is safe, extremely effective, broad-spectrum malodor control.
