Methods that ...
Therefore, manure was generated continuously from March 2021 onwards in each house. For these trials, manure from house C was used. The structuring agent used was chopped straw (5 mm), obtained from the 2020 wheat harvest. The volume of the mixture (poultry manure + straw) used in the ...
Ammonia recovery from chicken manure digestate using polydimethylsiloxane membrane contactor 2018, Journal of Cleaner Production Citation Excerpt : It proves that using higher air flowrates is not effective as expected. It is speculated that increased air flow rates reduces the thickness of the gas fil...
The distribution of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in cattle, swine, and chicken manure compost was analyzed. PCR-denaturing gradient gel electrophoresis (DGGE) showed that a Candidatus Nitrososphaera gargensis-like sequence dominated in cattle manure compost, while few AOA were ...
Anaerobic digestion of high solids chicken manure as a single substrate was conducted at laboratory scale with a reaction volume of 10 l. The organic loading rate was increased gradually from 2.2 to 3.9 gVS l -1 d -1 . To reduce the amount of inhibiting ammonia in the process technical str...
Ammonia assimilation is key for the preservation of nitrogen during industrial-scale composting of chicken manure 2023, Waste Management Citation Excerpt : Previous studies on ammonia assimilation during composting lack information on functional microorganisms and genes involved. However, many effective ammoniu...
(NH3) is the greatest concern for environmental pollution from poultry production. When birds consume protein, they produce uric acid, ultimately converted to NH3under favorable conditions. Factors that increase production include pH, temperature, moisture content, litter type, bird age, manure age, ...
are the two common forms of lime you will find in garden or home improvement retail stores. Adding a dry alkali such as lime accelerates the volatilization of the nitrogen in chicken manure, which releases the ammonia faster. Once the ammonia has gassed off, conditions inside...
The use of litter and manure in welfare-oriented systems for laying hens may negatively affect the air quality and the work environment. The objective of t... PWGG Koerkamp 被引量: 22发表: 1993年 EMPIRICAL MODELS TO DETERMINE AMMONIA CONCENTRATIONS FROM BROILER CHICKEN LITTER Volatilization of ...
Methane production from anaerobic digestion of chicken manure requires addressing the challenges posed by high nitrogen-containing substrates. One potential solution is the use of modified biochar to adsorb inhibitors and enhance the anaerobic digestion process. This study focused on preparing magnesium-...
