Comparison between Odor Removal Technologies: To Sewer Network

Bio Scrubber Flow Diagram To Sewer Network Air From Odor Source Intermittent Circulation Pump Two Stage Scrubbing Tower Neutralizing Agent Extraction Fan Collection Tank Make-up Water (TSE)

Design Input To Sewer Network  Capacity = 3000 m3/h  Average H2S = 40 ppm +/ ‐ 20%  Peak H2S = 250 ppm  Peak duration = 40 min 3 times a day

To Sewer Network Structured Polypropylene

To Sewer Network  Secondary wastewater, or make ‐ up water containing nutrients to the odorous air being treated.  The circulating solution and media are the ecosystem to supporting growth of biofilm sulfuroxidizing bacteria (thiobacilli).

To Sewer Network

Comparison between Odor Removal Technologies: To Sewer Network Bio ‐ scrubbers are very effective for H2S removal High robustness & reliability H2S inlet range is between 5 ‐ 1000 ppm Minimum of 98% removal capacity, and often is exceeding 99.9%
