Odor Control & Air Scrubbing

ChemE Solutions was called in to analyze and address these challanges. ChemE began by assessing all treatment programs, bench-testing chemistries and reviewing the operations of the 40,000 SCFM air scrubbers. ChemE Solutions then proposed key changes in two phases. First, ChemE modified the operating pH of the of scrubbers and begun adding Chlorine Dioxide to the recirculation water. Immediately, odor complaints receded. Next, ChemE initiated an dying systems evaluation. ChemE then made additional adjustments to the systems chemistry and flow pattern, resulting in a further reduction in odor complaints. By 2011, odor complaints were reduced to zero. In addition, the ozone treatment system was written out of the permit and shutdown, eliminating a major source of high-cost maintenance. The essential oils were also completely eliminated, further reducing costs. ChemE’s odor control expertise resulted in the reduction of the plant’s overall operating costs to a fraction of previous costs. ChemE Solutions continues to provide service and process engineering to this client.
