Abstract:
This paper’s primary objective is to examine the vapor delivery mechanism through a tubular membrane distillation (MD) module. Experiments were conducted utilizing a hydrophobic tubular membrane module with a pore size of 0.2 µm. To establish the mass transport mechanism of water vapor, tests were carried out first with pure water as a feed. The permeate flow was then determined using NaCl aqueous feed solutions. Distilled water flux at diverse feed temperatures, feed flow rates, and feed salt concentrations was investigated. The permeate flux improved linearly with rising temperature and flow

ABSTRACT The diversity of populations of yeast and lactic acid bacteria (LAB) in pig feeds fermented at 10, 15, or 20°C was characterized by rRNA gene sequencing of isolates. The feeds consisted of a cereal grain mix blended with wet wheat distillers' grains (WWDG feed), whey (W feed), or tap water (WAT feed). Fermentation proceeded for 5 days without disturbance, followed by 14 days of daily simulated feed outtakes, in which 80% of the contents were replaced with fresh feed mixtures. In WWDG feed, Pichia galeiformis became the dominant yeast species, independent of the fermentation temperatur

Freshwater fish communities segregate along water temperature gradients attributed in part to temperature-mediated physiological processes that affect species fitness. In spring complexes of southwest USA, spring complexes with narrow range of water temperatures are dominated by a community of fishes (i.e., spring-associated fishes), whereas riverine habitats with wide-range of water temperatures are dominated by a different community of fishes (i.e., riverine-associated fishes).

Abstract Coastal power plant temperature drainage represents a low-grade heat source that is directly released into the ocean, raising the temperature by 8–12°C above the normal seawater temperature. This discharge inevitably impacts the marine ecosystem. The Hydrophilic Porous Distiller (HPD) system, driven by the warm discharge from the power plant, uses non-woven pearl cotton as the porous medium. This material not only facilitates the production of fresh water but also helps reduce or even eliminate the thermal pollution caused by the direct release of temperature drainage into the ocean.

Abstract:
Pressure retarded osmosis (PRO) is considered as one of the promising and new techniques to generate power. In this work, a numerical model was used to study the effect of the flow streams temperature on the performance of the PRO process and entropy generation. The variation of the feed solution and draw solution temperatures, pressure difference, concentration difference, and flow rates on the power density and entropy generation were discussed. The model results were validated with experimental measurements obtained from literature and showed a good agreement with the model predictions. It

High environmental temperatures may cause heat stress in poultry. This may increase water consumption, decrease feed consumption and in turn, decrease production level. This experiment was conducted to study the supplementation of vitamin C as anti heat-stress agent of broilers. In this research, were used 72 broilers 21 days old. The treatment are two kinds. The first, two poultry house temperatures (32 and 240C as warm temperature and cool temperature respectively) and second, four levels suplementation of vitamin C (0, 250, 500 and 750 ppm of ration as C0, C250, C500 and C750 respectively)

Abstract:
Ammonia recovery from anaerobically digested cattle manure effluents through steam stripping was studied at a stripping tower temperature of 98–99 °C and a steam–water ratio approximately 56–72 g/L. The digested manure effluents were first treated by microfiltration and then the permeate was used as feed in steam stripping. The stripping performance was evaluated under different feed pH values, ammonia concentrations and temperatures. The increase of the initial feed pH does not significantly improve ammonia stripping efficiency due to the fact that the stripped effluent pH is increased during

The brine circulation multistage flash desalination process (MSF) dominates the thermal desalination market, while the once-through multistage flash desalination process (MSF-OT) remains to be found on a limited scale. This is because the MSF-OT process has no control on the temperature of the feed sea water. For non-equatorial regions, where the sea water temperature drops to 5 — 15°C during winter operation, the MSF-OT performance deteriorates unless the volume of the low-temperature stages is drastically increased to allow for reduction in the brine reject temperature to lower values.

Direct Contact Membrane Distillation (DCMD) is a promising and feasible technology for water desalination. Most of the models used to simulate DCMD are one-dimensional and/or use a linear function of vapour pressure which relies on experimentally determined parameters. In this study, the model of DCMD using Nusselt correlations was improved by coupling the continuity, momentum, and energy equations to better capture the downstream alteration of flow field properties. A logarithmic function of vapour pressure, which is independent from experiments, was used. This allowed us to analyse DCMD with
