The textile industry is one of the industries that generate a high volume of waste water. Strong colour of the textile waste water is the most serious problem of the textile waste effluent. The disposal of these wastes into receiving water causes damage to the environment. With regard to their colour removal by conventional treatment methods lead to severe water pollution, thus developing cost ...

In the absence of recycling, water represents over 90% of the life-support consumables for a manned spacecraft. In addition, over 90% of the waste water generated can be classified as moderately or slightly contaminated (e.g. shower water, condensate from the air-conditioning system, etc.). The ability to recover potable water from moderately contaminated waste water hence enables significant s...

Metrizamide is a water-soluble, nonionic radiocontrast medium that penetrates better into narrow subarachnoid spaces than do oily contrast media or gas. We performed metrizamide optic nerve thecography on five cats with iatrogenic orbital lesions. Optic thecograms successfully demonstrated displacement of the optic nerve, obstruction of the optic nerve sheath subarachnoid space, and extravasati...

The bioremediation of industrial waste water by macroalgae is a sustainable and renewable approach to the treatment of waste water produced by multiple industries. However, few studies have tested the bioremediation of complex multi-element waste streams from coal-fired power stations by live algae. This study compares the ability of three species of green freshwater macroalgae from the genus O...

[1] Organic‐coated aerosols are believed to play an important role in atmospheric processes thereby influencing global climate. In our earlier works involving water droplets coated with hydrocarbon chains (C, dodecanoic acid) we found that these particles prefer an inverted micelle structure with an aqueous core and a hydrophobic surface. Such particles maintained their overall spherical shapes...

The potential of using Effective Microorganisms (EM) to purify waste water, including that of a sewage system, for recycling purposes was evaluated. The studies were extended to examine the potential of using treated sewage sludge as a fertilizer in crop production. Long term application of EM reduced the adverse characteristics of waste water. The quality of the treated water was high, which i...

Residential domestic hot water (DHW) energy consumption represented 16% of the EU household heating demand in 2013. Due to the improvement of the building envelop, it is expected to increase significantly, with values between 20% to 32% in single family buildings, and between 35% to almost 50% in multifamily buildings. Currently, this energy is lost to the environment after its use, but it can ...
