Oct 1, 2008 · In comparison with other fermentation gases such as landfill or sewage gases, these manure gases are characterized by their high amount and diversity of selenium and tellurium species. Selenium-enriched duck food supplementation with tellurium impurities is suggested to explain the original presence of Se and Te in feather and/or excreta.
Apr 1, 2024 · 2.2. Fermentation operation. The mixed sludge and chicken manure were fermented at different pH under the optimal dosage ratio. The pH was adjusted by appropriate dosage of 2 M hydrochloric acid (HCl) or 2 M sodium hydroxide (NaOH) to 3.0, 5.0, 7.0, 9.0 and 11.0, respectively.
In view of the factors affecting fermentation with the mixture of duck manure and straw, and the cumulative gas production from raw material mixed in different proportions, optimum temperature for mixed anaerobic fermentation is about 30°C and the optimum proportion of raw materials is 2.8:1.
Oct 1, 2010 · The results showed that at (35±1)°C, biogas production potential of material (TS) was 0.273 m3/kg for sheep manure, 0.441 m3/kg for duck manure, and 0.210 m3/kg for rabbit manure.
When using duck manure water in hydroponics, your equipment gets dirty faster. It’s also trickier to maintain the right nutrient levels and pH than when using synthetic chemicals. So, aquaponics is often an easier system to use duck manure in than hydroponics. 2. Aquaponics. Aquaponics operates much like hydroponics using tanks and pumps
May 2, 2023 · For example, co-digestion of cow manure and duck manure , swine manure and corn straw , and cow manure and chicken manure have achieved good biogas production performance.

Sep 10, 2022 · Ectopic fermentation systems (EFS) provide a novel method for the efficient and simultaneous treatment of feces and urine (Guo et al., 2015; Shen et al., 2019), which could resolve the outstanding problem of solid–liquid manure separation treatment. In conventional EFS, livestock waste is successively diverted into paddings and fermented by
May 27, 2022 · The organic fertilizer manufacturing process is to use the synergistic effect of various microorganisms to convert duck manure into bio-organic fertilizer that is beneficial for plant growth and utilization. After being applied to the soil, the soil has a high organic matter content and relatively good quality, which can provide comprehensive
Apr 1, 2024 · Initial stages of fermentation saw a decrease in moisture due to evaporation propelled by the rising temperatures (Wang et al., 2017). Subsequent additions of wastewater and manual inversions successfully maintained moisture equilibrium. Throughout the fermentation, pH ranged between 8.0 and 9.0, displaying marginal variations among layers (Fig
Jul 1, 2023 · The fermentation site was set in an outdoor rectangular fermentation tank, equipped with a turning machine (FP2600, China).
