Establishment of great industrial centers and ports along the Khur-Musa Estuary in Mahshahr Port (Khuzestan, Iran) have been discharged a high volume of industrial and non-industrial pollutants to this estuary. The most important pollutants in Khur-Musa include industrial wastes and effluents including ammonia and urea units. This research aimed to survey the qualitative parameters of effluent ...
In order to evaluate the effects of three organic (Formic, Acetic and Propionic acid) and two inorganic acids (Sulfuric acid and HCL) at different levels (0, 1, 2.5 and 5% (vol/wt)) on dry and organic matter, NDF, CP and ammonia-N content and pH of Iranian clover silage and its ruminal dry matter and nutrients degradability, this experiment carried out using a complete randomized design with 5×...
In this study, an indoor fish farm was selected to assess the biological treatment of the waste effluents. The purification lagoon surface was completely grown by target species, Nasturtium aquaticum. Six stations were selected as the water source, the farm outlet, the starting point of outlet water to the lagoon and three next other sampling stations. The averages of many chemical parameters ...
conclusions the results indicated that the model, compared with other models, was user-friendly and the desired results were obtained by a minimal data. materials and methods the current paper developed a process model. first, a sketch of nitrate and ammonia storage, their specifications and parameters were set out and created on a page, and then, mathematical relations of each process were set...
Hematological parameters are useful indicators for assessing the physiological conditions of Sturgeon in response to stress, pollutants and physiological and ecological changes. The aim of this study was to investigate the effects of nitrosomonase and nitrobacter in removing ammonia and on blood and serum indices of Huso huso .Four treatments were designed with densities of bacteria (0, 101, 10...
Background and Objectives: Pulmonary consequences of exposure to low concentrations of ammonia have been less studied. The purpose of this study was to model the pulmonary consequences of exposure to low concentrations of ammonia. Methods: This historical cohort study was conducted in the fertilizer industries in 2019. The participants were divided into two groups of exposed (n=98) and non-...
This paper discusses the performance evaluation and availability analysis of ammonia synthesis unit of a fertilizer plant. The fertilizer plant is a complex and repairable engineering system comprises of various units viz. shell gasification and carbon recovery, desulphurization, co-shift conversion, decarbonation, nitrogen wash and ammonia synthesis etc. One of the most important functionaries...
