Jan 13, 2021 · This review summarizes the latest progress on genetic background, genetic transformation system, and bioreactor development of duckweed, and provides insights for further exploration and application of duckweed.

Jun 23, 2011 · Bioreactors were operated at 20 and 25 °C, and ground swine carcasses were co-digested with swine manure slurry. The manure fed to the bioreactors contained 20–40 g of swine carcass/L, representing 4–8 times normal mortality rates on commercial Canadian swine farms. The system modeled high mortality rates that would occur as a result of a

Jan 7, 2021 · Pen or pencil to mark places that will be cut. Building the Reactor. With scissors, cut a piece of landscaping fabric to 13’ in length and 6’ in height (if using the DeWit barrier, you’ll need to connect two 3’ wide pieces). Using bolt cutters or pliers, cut the re-mesh to 12’6” in length and 5’ in height.

Swine manure wastewater was treated in an anaerobic membrane bioreactor (AnMBR) that combined a continuous stirred tank reactor (CSTR) and a hollow-fiber ultrafiltration membrane, and the feasibility of ammonia and phosphorus recovery in the permeate was investigated. The AnMBR system was operated s

Jan 13, 2021 · The results showed that the average removal values of selected ARGs were respectively 2.56 and 2.09 log units in duck and pig manure compost without the addition of biochar.

Nov 11, 2022 · Acidogenic fermentation of chicken manure (CM) for production and recovery of volatile fatty acids (VFA) is an interesting biological waste-to-value approach compared to benchmark organic waste management strategies. Considering the wide range of high value applications of VFA, a semi-continuous immersed anaerobic membrane bioreactor (AnMBR) was applied to boost VFA productivity and yield

Jun 1, 2023 · Duck manure is a good fertilizer for your plants because it has an evenly balanced NPK ratio. 3. Safety. Safety is a key consideration when working with animal manure. Fresh animal manure can burn your plants. Many gardeners recommend using only decomposed or composted manure in a garden.

An experimental study worked on a model biogas production unit which has 0.5 m fermentation tank capacities of a breeding farm in the Urla district of Izmir/Turkey. The farm animal quantity is 70 cattle and 1400 chicken. Animal wastes (poultry manure and bovine animals manure) were anaerobically fermented in the tank. It is known in literature, the optimum fermentation occurs at 298-313 K

Jan 3, 2021 · Anaerobic co-digestion (AD) of different organic wastes is a promising technique to enhance clean energy (bioenergy) and manure (slurry) production, reducing stress on the environment. This is an experimental study aimed to investigate 2-stage co-digestion of pretreated organic wastes mixed with fresh animal manure (BD) and digester’s operation conditions (digester temperature and pH) to

Oct 19, 2021 · In open pond systems, S. polyrrhiza in organic manure and inorganic fertilizer is high in protein and carbohydrate contents, respectively . Duckweeds grow rapidly even in animal wastewater, producing high biomass .

Jan 1, 2009 · To our knowledge, this is the first investigation using LH-PCR to monitor shifts in the bacterial community involved in the anaerobic digestion of swine manure. Download : Download full-size image; Fig. 1. Schematic diagram of the 8-compartment plug-flow type bioreactor. Compartments PF01–PF08, with PF09 representing the effluent.

In this study, the removal of volatile solids (VSs) and soluble chemical oxygen demand (SCOD) by co-digesting cattle dung (CD) and duck manure (DM) was determined and compared with the reduction achieved with CD or DM digestion alone. Moreover, fluorescence excitation-emission matrix spectroscopy wa

Jun 1, 2022 · By combining enzyme pretreatment and semi-simultaneous saccharification and fermentation (SSSF), 75.46 g L −1 SA was obtained from 180 g L −1 substrates in a 2 L bioreactor. Duckweed can also be used to produce other high-value products by pyrolysis.

Nov 1, 2018 · Experiments of anaerobic digestion of brown Tsaiya duck's wastewater had been performed by using duck manure and tap water mixture as the target of duck house wastewater (Su and Wang unpublished data). All wastewater samples were taken and analyzed by a gas chromatography in triplicates periodically.

Oct 1, 2023 · Biochar-immobilized functional bacteria Bacillus SDB4 was applied for sulfamethoxazole (SMX) and zinc (Zn 2+) simultaneous removal in the bioreactor.Under the optimal operating conditions of HRT of 10 h, pH of 7.0, SMX concentration of 10 mg L −1 and Zn 2+ concentration of 50 mg L −1, the removal efficiencies of SMX and Zn 2+ by the immobilized reactor (IR) were 97.42% and 96.14%
