Opis:: The increasing demand for water with the industrialisation of the world is becoming a major problem as there is a water shortage all over the earth. Therefore, the water problem is one of the important problems that need to be effectively solved. This paper presents the results of research on wastewater treatment of bitumen production in the Mangystau region, which after physical and chemical treatment methods is sent to natural evaporation fields. As a result of research work, a method of wastewater treatment of bitumen plant was developed, which includes two stages: distillation of water on the solar plant and ozonation in order to oxidize volatile organic matter. Distillation to obtain primary treated water of 70–75% volume was carried out at 33–37 °C ambient temperature and 15–30 kPa rarefaction, at the same time COD of water was reduced by 68%.

Opis:: One of the ways of charcoal producing is its calcination in charcoal kilns called retorts in field conditions. In the charcoal production wood of deciduous trees is being subjected to the process of dry distillation. The process affects the surrounding environment. During the process a lot of pollutants are emitted to natural environment. One of them is ash, which contains heavy metals. The paper aimed at determining the effect of charcoal calcination on heavy metal content in the soil and plant material in the immediate vicinity. Charcoal calcination causes the alkalinization of the soil to 10 metres. In the closest vicinity, the calcination process increases Mn, Cd, Ni and Cu concentrations in the soil material. The influence of charcoal production on the concentrations Fe, Zn, Pb, Cr in soil material cannot be determined unanimously. The effect of the process on heavy metal content in plant material cannot be determined unanimously.

Opis:: The pressing need for reducing the global warming effects from the emission of greenhouse gases necessitates the use of renewable energy where possible. Solar distillers are devices with a promising future. In this work, an experimental setup (solar distiller) was constructed and equipped with a mirror, basin, glass cover, compressor, sensors and controllers to study the partial evacuation effects on different solar distillation parameters and the production capacity under the Jordanian climate. The test rig was tested for three different water levels (1, 2 and 3 cm), and four pressure values (1, 0.9, 0.8 and 0.7 atm) under the Jordanian climate. The detailed experimental results strongly correlate with the results previously published in literature. The modifications performed on the system doubled the previously attained efficiency. These improvements in the solar distiller will favor the application of the vacuum pressure principle in many different applications, such as the water extraction from the atmospheric air.
