Effects of temperature (mesophilic (35掳C) vs. thermophilic (55掳C)) and dissolved oxygen (DO) concentration (under thermophilic conditions) on sludge properties and their role in bioflocculation and settling were studied using well-controlled sequencing batch reactors fed with a synthetic wastewater...
Re: Question regarding dissolved oxygen and temperature (Winkler Titration) « Reply #3 on: June 29, 2021, 05:10:49 PM » Quote I measure the levels of dissolved oxygen in varying temperatures of water through the Winkler Method, but I came across a bit of an issue. If I were to...
We identified fish traits that significantly correlate with both temperature and chlorophyll-a concentration optimum: reproduction habitat, oxygen tolerance, and toxicity tolerance. Compared to other ecological groups, lithophilic species exhibited the lowest degree of thermal and eutrophication optimum, indica...

15.6H2SO4+H2O+SO2+(1/2)O2(oxygen generation) Hydrogen generation of eqn 15.5 is carried out by means of electrolysis, and the method of oxygen generation is the same as the IS process. The system of this process can be simplified because the iodine process is not used. However, ...
Otolith Sr/Ca values were also significantly higher at a salinity of 25‰ vs. 15‰, after accounting for differences in dissolved Sr/Ca ratios in the ambient water, with a sensitivity of approximately 1%/salinity (‰). These observations complicate the use of Sr/Ca ratios to determine ...
aThe amount of O2, dissolved in aqueous solution depends on the temperature, the partial pressure of oxygen, and ionic strength of the solution [13]. In a given volume of headspace sample vial, the percentage of the oxygen in the headspace (vs. the total amount of oxygen in the vial) ca...
(psu), dissolved oxygen (mL/L), and chlorophyll a fluorescence (µg/L) were measured for depths from 0 to 1000 m at two stations whereA. japonicaandA. marmorataleptocephali were collected (16°N, 137°E and 14°N, 137°E, respectively) on 16 and 17 July 2016 (Fig.3). Based ...
Different studies have examined selective withdrawal impacts on in-reservoir and downstream temperatures3,4and downstream temperature/in-reservoir dissolved oxygen (DO) tradeoffs5. In particular, the 2D hydrodynamic water quality CE-QUAL-W2 model6has used to examine dam flow control impacts on water ...
Further, the H2production performance was analyzed (Fig.1e). On the second day of AD, H2production peaked in MG, HG, UG, and GG at 11.215, 20.23, 13.439, and 5.08 mL/g VS, respectively. As shown in Fig.1f, after 8 days, the cumulative H2production were 14.56, 24.13, 26.01, and...
