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). The purpose of this study was to test a prediction of the concept that temperature-mediated species performance is

When using the electrolyzer voltage, current, liquid water feed rate and temperature, the electrolyzer operating temperature can be calculated. Heat losses can also be accounted for but are currently neglected. Carpet plots show the resulting electrolyzer temperature under varying conditions. The calculated temperatures are in very good agreement with measurements conducted in our laboratories.

Subsuming these previous accounts, stratified reference correctly predicts the monotonicity constraint: such constructions disallow measure functions that generally return the same value on an entity and on its parts.

AbstractIn aquaponics, nutrients originate mainly from the fish feed and water inputs in the system. A substantial part of the feed is ingested by the fish and either used for growth and metabolism or excreted as soluble and solid faeces, while the rest of any uneaten feed decays in the tanks. While the soluble excretions are readily available for the plants, the solid faeces need to be mineralised by microorganisms in order for its nutrient content to be available for plant uptake. It is thus more challenging to control the available nutrient concentrations in aquaponics than in hydroponics.

Rapid failure of the reactor due to intergranular corrosion was observed in the reactor at a point where the temperature of the water feed was in the high subcritical range. The cause for the corrosion was not determined, however, it appears to be related to a proprietary carbonate in the water feed.

Safety concerns have driven cooling system users to implement alkaline treatment programs to facilitate acid feed reduction or elimination. Inorganic and/or organic phosphorus components in alkaline cooling water treatment (CWT) programs help prevent corrosion and scale formation. Collectively, water conservation measures and alkaline CWT programs have increased potential metal-phosphate and/or metal-phosphonate scale formation.

Abstract In the boiler water system, it is apparent that use of low volatility amine is effective to control pH of feed water and to maintain boiler water at higher pH even though makeup water is contaminated with organic substances which thermally decompose to organic acids. Various amines were characterized in the view of volatility, thermal stability and dissociation behavior at high temperature by using experimental boiler apparatus with maximum pressure up to 10.5 MPa and with maximum exhausting steam temperature up to 600 °C after attached superheater. One low volatility amine which is s

The Reverse Osmosis (RO) system has the potential as a vibrant technology to generate high-quality water from brackish water sources. Nevertheless, the progressive growth in water and electricity demands necessitates the development of a sustainable desalination technology. This can be achieved by reducing the specific energy consumption of the process, which would also reduce the environmental footprint. This study proposes the concept of reducing the overall energy consumption of a multistage multi-pass RO system of Arab Potash Company (APC) in Jordan via heating the feed brackish water. The

Abstract A diffusion based controlled release technology is now being used as a method to introduce chemistry into an open recirculating cooling system. Controlled release technology applied to a cooling tower water treatment program enables accurate delivery of chemistry without the use of mechanical pumps or handling of liquid chemicals. Our laboratory work examined how factors such as formulation, temperature, flow, and coating weight affect this feed method. In addition to the technology overview, case studies of current applications will be presented.

In this paper, we present a systematic approach to quantify the safe operating window of a proton exchange membrane water electrolysis (PEMWE) system considering energy intermittency and varying hydrogen demand. The PEMWE model has been developed based on first principles, with the polarization curve validated against a lab-scale experimental setup. The impact of key operational variables is investigated which include voltage, inlet temperature, and water flowrate (utilized for both feed and system cooling). Emphasis is given on operating temperature, a safety-critical variable, as its elevati

Abstract Thermal desalination processes involve the heating of seawater to form water vapor which is then condensed to produce salt free water. Multiple Effect Evaporation (ME) and Multiple-Stage Flash distillation (MSF) are the two main processes used for thermal distillation. MSF distillation, currently is the dominant process. MSF distillation is run under pressure at relatively high temperatures (90-125 °C). Scale formation is one of the most critical problems affecting both processes. In the case of MSF, calcium carbonate, magnesium hydroxide and calcium sulfate are the main scale forming

To probe the influence of dissolved oxygen content on corrosion, the dissolved oxygen contents were controlled at 0, 100, 300 and 2000 ppb, respectively. The exposing time was 200, 400, 600, 800 and 1000 h. The surface morphologies and composition were observed using SEM, EDS and XRD. The cross-sectional structure and element distribut

Several bitumen samples from AOSTRA's Underground Test Facility were obtained (heat exchanger outlet) in order to characterize the emulsion droplet size distribution and to ultimately establish whether or not high temperature settling could successfully be used to separate the bitumen and water phases. Characterization of the dispersed phase was not straightforward since the samples varied. The samples would sometimes be separated into a large bitumen mass and significant free water and sometimes be quite fluid with dispersed bitumen. It was our opinion that sampling contamination, perhaps wit
