A full-scale integrated-bioreactor with two zones treating odours from sludge thickening tank and dewatering house: performance and microbial characteristics

Full-Scale Odor Abatement Technologies in Wastewater Treatment Plants (WWTPs): A Review

“…In the Subiaco Wastewater Treatment Plant (Western Australia, the waste gas flowrate of 65,000 m 3 h −1 , 75 ppm H 2 S and 5 ppm NH 3 ), a biofilter installed after the acid scrubber to promote the formation of a biofilm for H 2 S removal, was then moved to the inlet of the scrubber to treat H 2 S and NH 3 mixtures [63]. BFs were also used to treat odors from the sludge thickeners, effluent channel and influent splitter box at the Mill Creek WWTP of the Metropolitan Sewer District of Greater Cincinnati [64] and in Shandong, China with PU packing materials [65]. The REs, in terms of H 2 S and NH 3 concentrations, to be higher than 90%.…”

“…Some papers dealt with the use of different packing materials to enhance biofiltration in municipal WWTP including peat [69] (Charguia, Tunisia with inlet H 2 S concentrations ranging between 200-1300 mg m −3 ), seashells [70] (Lake Wildwood WWTP, California with 55,200 L h −1 of wastewater flowrate and air flowrate of 28,300 L min −1 ), polyurethane foam [65] (Shandong, China, H 2 S, NH 3 and VOC inlet concentrations were 0.5-28.4, 0.9-34.3 and 0-0.9 mg m −3 , respectively), advanced biofiltration with organic and inorganic phase in the medium [71] (Mallorca, Spain with air flow rate of 15,000 m 3 h −1 ), packed waste straw and cortex [72] (refinery WWTP in Shanghai, China). Using the modified packing materials, biofiltration was demonstrated to be an optimum OTT by having 90-99% RE.…”

“…Plastic fibers (i.e., polyurethane foams) are preferred in some studies to enhance the BTFs' removal performances [65,83]. In terms of operation, the BTF requires relatively low power, since only the pumping phase requires energy and an aeration blower is not needed.…”

Research on the degradation of hydrogen sulfide by sulfur oxidase using Ruegeria pomeroyi DSS-3

“…Biological degradation of sulfur-containing odorant in water and air by a newly isolated strain in active sludge or sediments has been reported extensively. For instance, methanogenic bacteria (Sipma et al, 2002) The isolated bacteria to eliminate H 2 S were also popularly studied, for example, Thiobacillus thiooxidans (Liu et al, 2017) and Acidithiobacillus thiooxidans (Zhou et al, 2015).…”
