PURPOSE: A system for removing dissolved ammonia in fish farm is provided to strip dissolved ammonia generated from excretions of fish, and recycle ammonia-stripped water, therefore it can help the growth of fish. In the system, heat source (latent heat) generated from a preliminary heat ...
Question: Explain how the stress of removing crabs from their aquatic habitat, emersion, affects their hemolymph glucose levels. Stress Response: Stress is a physiological response that occurs when the body perceives a threat to homeostasis, which is the ...
In the presence of strong chelants or free ammonia dissolved in alkaline solutions, a large excess of this source of ferrous ion is required. Normally, 5 to 10 ferrous ions are added for each copper ion being removed from chelated waste-waters. In heavily chelated streams, as many as 25 ...
PURPOSE: A system for removing dissolved ammonia in fish farm is provided to strip dissolved ammonia generated from excretions of fish, and recycle ammonia-stripped water, therefore it can help the growth of fish. CONSTITUTION: In the body (A), a preliminary heat exchange part (10) equipped ...
More than 84% ammonia nitrogen was adsorbed from the water samples coming from the fish pond for both types of sorbents in the batch tests, while 47.7% and 26.3% NH4+ were adsorbed from the same water samples for the fine-grained sorbent and the coarse-grained sorbent, respectively, in ...
minor reduced the concentrations in total nitrogen ammonia and total phosphorus by 43.7% and 52.38%, respectively [37]. Liu et al. [38] investigated the efficiency of L. minor in removing nitrogen (N) and phosphorus (P) from industrial wastewater, in relation to the salinity level in water...
