“…A German study (Martinec et al, 1998) indicated that laying hens generated an odour emission rate of approximately 0.5 ou E s -1 bird -1 . Sutton et al (1995) estimated an ammonia emission factor for poultry (layers and broilers) of approximately 0.6 g day -1…”

Publication informationBioresource Technology, 97 (7) AbstractOdour and ammonia emissions were measured from three broiler, two layer and two turkey houses in Ireland. The broiler units gave a large range of odour and ammonia emission rates depending on the age of the birds and the season. A considerable variation between the odour and ammonia emission rates was evident for the two layer units which may be due to the different manure handling systems utilised in the houses. There was relatively little difference in the odour and ammonia emissions from the two turkey houses. As a precautionary principle, odour emission rates utilised in atmospheric dispersion models should use the maximum values for broilers and turkeys (1.22 and 10.5 ou E s -1 bird -1 respectively) and the mean value for the layers depending on the manure handling system used (0.47 or 1.35 ou E s -1 bird -1 ).

“…Sun et al 12 observed an average H 2 S removal efficiency between 93 and 94% and an average NH 3 removal efficiency between 90 and 76% with 50% media moisture content and 20-sec gas residence time. Martinec et al 13 also found an odor reduction efficiency up to 95%.…”

A pilot-scale biofilter was developed in which two types of wood chips (western cedar [WC] and 2-in. hardwood [HW]) were examined to treat odor emissions from a deep-pit swine finishing facility in central Iowa. The biofilters were operated continuously for 13 weeks at different airflow rates resulting in variable empty bed residence times (EBRTs) from 1.6 to 7.3 sec. The effects of three media moisture levels were also evaluated. A dynamic forced-choice olfactometer was used to evaluate odor concentrations from both the control (inlet) plenum and biofilter treatments (outlet). Hydrogen sulfide (H 2 S) and ammonia (NH 3 ) concentrations were also measured from these olfactometry samples. Solid-phase microextraction (SPME) polydimethylsiloxane (PDMS)/ divinylbenzene (DVB) 65-m fibers were used to extract volatile organic compounds from both the control plenum and biofilter treatments. Analyses of separated odors were carried out using a gas chromatographymass spectrometry-olfactometry (GC-MS-O) system. Static sample results indicated that both types of chips achieved significant reductions in odor (average 70.1 and 82.3% for HW and WC, respectively), H 2 S (average 81.8 and 88.6% for HW and WC, respectively) and NH 3 (average 43.4 and 74% for HW and WC, respectively) concentrations. GC-MS-O aromagram results showed both treatments reached high odor reduction efficiency (average 99.4 and 99.8% for HW and WC, respectively). The results also showed that maintaining proper moisture content and a minimum EBRT are critical to the success of wood chip-based biofilters.

“…Although much experience has been gathered with biofiltration for odor removal, currently in livestock farming there is no experience with biofilters that are designed for methane removal and research in this field is scarce (Hahne and Vorlop, 2001;Martinec et al, 2001). In other areas, however, some experience has been gathered.…”

Intensive livestock production is connected with a number of environmental effects, including emissions of ammonia (NH 3 ), greenhouse gases (CH 4 and N 2 O), odour, and particulate matter (PM10 and PM2.5). Possible strategies for emission reduction from animal houses include feed management, adaptation of housing design, and the application of end-of-pipe air treatment, viz acid scrubbers and bioscrubbers. In order to comply with current and future regulations the implementation of air scrubbers is expected to expand in intensive livestock production areas across Europe. The aim of this thesis is to better understand and improve the performance of air scrubber systems in livestock operations. The objectives are to determine (1) how air scrubbers are performing at livestock farms with regard to ammonia and odour removal; (2) how the cost-efficiency of air scrubbers can be increased by applying a different treatment strategy; (3) if methane can be removed by biological air treatment systems; and (4) to discuss the drawbacks of current air scrubbing practices and make recommendations for improvement.It was found that ammonia removal efficiency by scrubbers is relatively high (on average 96% for acid scrubbers and 70% for bioscrubbers), that odour removal is relatively low (on average 31% for acid scrubbers and 44% for bioscrubbers), and that especially bioscrubbers often show a large variation in odour removal efficiency. Furthermore, it was found that bioscrubbers often experience operational problems. Next a partial air cleaning approach has been presented in which air is bypassed at occasionally occurring high air flow rates. Model calculations show that a reduction of scrubber volume by 50% still enables treatment of 80 -90% of the ammonia load. This strategy reduces investment and operational costs but hardly affects average ammonia emission levels. Furthermore, it was demonstrated that biological oxidation of methane is possible, although the low water solubility of methane limits the practical application of biofilters or bioscrubbers for methane removal. Finally, it is concluded that scrubbers applied at animal houses can still be improved and optimized. For example the process control and performance of bioscrubbers might be enhanced by measurement of electrical conductivity (EC) as a control parameter for water discharge.
