17. The results showed that the compound microorganism preparation improved water quality and decreased significantly the ammonia nitrogen in water. 试验表明,复合微生物制剂对改善水质,降低水体中的氨氮具有明显作用。 18. Influence factors and rules for adsorption and ion-exchange of ammonia nitrogen by ze...
Groundwater ammonia pollution is well investigated worldwide as well as in Viet Nam. The products of its conversion process, namely nitrite and nitrate, cause the toxicity of ammonia in water. In addition, the existence of ammonia in water causes the modification of water taste and smell, ...
This paper discussed the influence on the biochemical oxygen demand, ammoniation and nitrosation by barium of different levels in water.本文就不同浓度的钡对天然水的生化需氧过程、氨化及亚硝化过程的影响进行了探讨。Areas of technical support will include cow - calf management, crop by - product and ...
R. Miller, in Encyclopedia of Food and Health, 2016 Ammonium bicarbonate Ammonium bicarbonate decomposes during baking to produce ammonia gas, carbon dioxide gas, and water. All three of these products act as leaveners. Because ammonia gas dissolves in water, it can be retained in moist products...
Nitrosomonas europaea, a model AOB, has been found to be a key AOB in terrestrial and freshwater habitats, especially those containing high levels of NH4+, including WWTPs (Kowalchuk and Stephen, 2001; Mobarryet al., 1996), and has been used in pure culture studies to gain a greater unde...
dose. If the fish shows a red streaking on its fins or elsewhere on the body, this too could be indicative of high levels of Ammonia in the water. Loss of appetite is another common symptom. If the gills of the fish become red or purple, Ammonia levels need to be checked immediately....
Ammonia (chemical formula: NH3) is a compound of nitrogen and hydrogen. As a colorless pungent gas, it is highly soluble in water to become the liquid ammonia. It is also one of the most abundant nitrogen-containing compound in the atmosphere. It provides the fundamental nutrients demands for...
