Ammonia has been used on a small scale in other industrial equipment, such as gas turbines, carbon-free fuel. However, ammonia fuel suffers disadvantages high ignition temperature, low flame velocity and NO x emissions. Doping with using more reactive fuel, methane, can solve the above problems. Therefore, under relevant operating conditions of turbine ( T = 723 K, p 16.5 atm), effect content c...

A study was conducted to determine the effects of solid‐liquid separation of liquid swine manure on ammonia emissions from lagoons. This determination was done at full‐scale in two contiguous swine production units that had similar animal production management. One of these units was maintained as a control using the anaerobic lagoon treatment method. In the second production unit, solids were ...

In 1921 Nash and Benedict (11) advanced the hypothesis that urinary ammonia is formed in the kidney from some precursor in the blood. This conclusion was based upon the observation that the concentration of ammonia was higher in the renal vein than in the renal artery, that the quantity of ammonia in arterial blood was too small to supply the ammonia found in the urine, and that the arterial am...

background: leachatecontaining high levels of organic pollution with ammonia, halogenatedhydrocarbons, heavy metals and inorganic salts. among the various methods fortreating leachate, has been developed membrane processes so that a morebiological process of membrane processes is used for separation of solid -liquid. the aimof this study was to evaluate the efficiency of membrane bioreactor eff...

We studied in meroxenic lambs, i.e. in lambs with a simplified digestive microflora, the effect of the microflora on the quantities of solid feed intake and on the main digestive parameters in the rumen. Axenic lambs were inoculated with a more or less complex flora, obtained by diluting (10(-8), 10(-7), 10(-8) a pool of rumen fluid taken either from young conventional lambs before weaning from...

An aquaculture system can be a potentially significant source of antibacterial compounds and ammonia in an aquatic environment. In this study, the removal of total ammonia nitrogen and florfenicol antibiotic from synthetic aqueous wastewater was assessed by applying a commercial TFC (thin film composite) polyamide nanofilter. The effects of pH (6.5-8.5), pressure (4-10 bar), concentration of to...

This study evaluated the effect of Candida norvegensis (C. norvegensis) viable yeast culture on in vitro ruminal fermentation of oat straw. Ruminal fluid was mixed with buffer solution (1:2) and anaerobically incubated with or without yeast at 39°C for 0, 4, 8, 16, and 24 h. A fully randomized design was used. There was a decrease in lactic acid (quadratic, p = 0.01), pH, (quadratic, p = 0.02),...
