A new absorption vapor compression distillation was proposed in present research. An open absorption heat transformer has a coupled thermally evaporator and absorber. Distillation of waste water with high content of SiO 2 from heavy oil production. The waste heat of 70 C can be elevated up to 125 C and generate steam of 120 C. The waste heat is able to drive four-effect distillation to produce ...

THE use of contrast media in the orbit dates from 1927, when Staunig and Herrenschwand injected air into the episcleral space, and since that time various media have been used. The ideal medium should provide good contrast in small quantities, be non-irritant, and have suitable qualities of permeation and absorption. The following media will be considered: (1) Air or other gas, (2) Oily media, ...

Within the literature, capillary barriers have been suggested as an alternative hydraulic barrier in cover liners for waste dumps. When a waste dump reaches its full capacity, cover liners are usually constructed over the waste mound to seal the waste from the surrounding environment. One main function of a cover liner is to prevent substantial amounts of water infiltrating into the waste mater...

Waste stabilization ponds (WSP) have been used world-wide over the last 50 years for municipal and industrial wastewater. The waste water treatment system has been accepted and used to change the physical, chemical, or biological character of the waste. This article presents the characteristics, parameters, and examples of the waste stabilization ponds all over the world. This work was based on...

background: contamination of water by toxic chemicals has become commonly recognized as an environmental concern. based on our clinical observation in mashhad, northeastern iran, many people might be at risk of exposure to high concentrations of toxic heavy metals in water. because wastewater effluents as well as water wells have been commonly used for irrigation over the past decades, there ha...

Oily wastewater and oil spills pose a threat to the environment human health, absorbing these harmful organics through porous aerogel materials is an efficient method for oil/water separation.

The development of the leather industry in the Aojiang watershed of Zhejiang province increased the release of waste water. In the waste water, ammonium nitrogen (NH(+) (4)-N) and germanium (Ge) are the main pollutants. In recent years, literature has documented that the intake of high concentrations of NH(+) (4)-N and Ge harms human health and biological species. This paper focuses on assessin...

The volume of e-waste is growing around the world, and, increasingly, it is being disposed of by export from developed to developing countries. This is the situation in Ghana, and, in this paper we address the potential consequences of such e-waste disposal. Herein, we describe how e-waste is processed in Ghana, and what the fate is of e-waste-chemical contaminants during recycling and storage....
