Oct 1, 2023 · Thus, strategies and alternatives are necessary to avoid off-flavors and odors. Deodorization is an important step in removing off-flavor substances from algal biomass used as foods and ingredients, such as volatile compounds and free fatty acids. These substances are attenuated when thermal processes are used in biorefining.
Nov 10, 2016 · Tank Odors. When new feedstock is introduced into a holding tank, all of the odorous air in the tank is purged, which can be very problematic if it isn’t captured and treated. Fixed roofs on storage and tipping tanks are recommended. These roofs allow operators access and can contain the gases that come from odorous feedstocks.
ABC Machinery offers two types of composting equipment: organic fertilizer fermentation tanks and compost turners. Among them, the processing time of the organic fertilizer fermentation tank only takes 7 days, which greatly improves the production efficiency.
Dec 1, 2019 · The low odor threshold characters of the major odorants pose a challenge for deodorization of the fermentation off-gas. The odor activity value of a compound is determined by dividing the chemical concentration of the compound by its OTC (Shen et al., 2012; Wu et al., 2017). It means the concentration of 2-MIB and geosmin has to be reduced to
The utility model belongs to the technical field of the aerobic fermentation technique and specifically relates to an aerobic fermentation jar that possesses deodorization structure, which comprises a tank body, the welding of the two bisymmetry in bottom of the jar body has the supporting leg, the top joint of the jar body has sealed lid, the mid-mounting of sealed lid has rabbling mechanism
Jan 1, 2022 · SIFT-MS involves the chemical ionization of trace volatile compounds by selected positive precursor ions. This method can be used for diverse odor compounds at extremely trace levels in the air with higher sensitivity than PTR-TOF-MS and GC–MS (Billiau and Mcewan, 2020). Based on the data obtained from these , the odor activity value
Jun 30, 2022 · The yeast Saccharomyces cerevisiae is effective in reducing the fishy malodor of sea products. However, the biotransformation pathways are still unclear. The seaweed B. fusco-purpurea was taken as an example to investigate the chemical transformation pathways for the deodorization process with S. cerevisiae fermentation.
A kitchen waste treatment plant in Jiangsu, China has six digestate fermentation tanks with a treatment capacity of 30 t/tank, a tank temperature of 25–55 ℃, and a kitchen waste treatment capacity of 10–15 m 3 /day. The fermentation tanks have a cycle from feeding to discharging, which takes about 30 days.
2. There is a bad smell in the chicken house, breeding bacteria and flies, which are often complained by neighbors？ 1.Working principle for the fermentation tank. Manure fermentation is a biological process that converts raw poultry manure into a more stable, nutrient-rich product.
An effective approach for getting rid of odors is to decompose and transform odor sources and degrade organic substances in odor sources. It reduces ammonia and nitrogen content, thus eliminating odors effectively. Also, it can inhibit odor reoccurrence afterwards. Specifically, it targets hydrogen sulfide, ammonia, and other malodorous gases.
Feb 4, 2019 · There is an increasing number of citizens’ complaints about odor nuisance due to production or service activity. High social awareness imposes pressure on entrepreneurs and service providers forcing them to undertake effective steps aimed at minimization of the effects of their activity, also with respect to emission of malodorous substances. The article presents information about various
Nov 1, 2016 · The article presents basic information on the characteristics of odors from wastewater treatment lines and wastewater processing and management lines in a model biological wastewater treatment plant conducting the biogas recovery process and also information is provided on deodorization , such as odor masking, biofiltration, thermal
Using chemical deodorization the offensive odor is neutralized or immobilized by chemical reactions and is changed into material of low odor level. Fiber manufacturers immobilize such material on a fiber easily using blasting processing. However, the method is limited because chemical deodorization uses harmful chemical reactions.
