PHYSICO-CHEMICAL PROPERTIES OF SOIL FROM
AROUND THE RADEȘ DUMP/ALBA COUNTY
Mining activity carried out in the past has led over time to the pollution of large tracts of land to impaired quality of the environment and human health. This paper presents physical-chemical soil around the mine Rades in choosing the most appropriate technology to remedy it. The results showed that the soil in the study area is well and poorly structured, humidity is higher upstream landfill (35.13 %) and lower downstream from it (16.36 %.) And soil pH is acidic to slightly acid values falling in the range of 4.8-6 pH units.

HEAT EXPLOITATION AND RECOVERY FROM SECONDARY ENERGY SOURCES WITH HEAT DOWN POTENTIAL
The reduction of energy consumption or the heat recovery from different sources is an increasingly important activity both at EU. Facilities commonly used for heat recovery are heat exchangers, and heat pump. Starting from this paper, it was considered appropriate to approach a research on the heat recovery using heat exchanger form wastewater. The potential of wastewater, types of heat exchangers and their applications is discussed. In this study, is presented a reiew of heat exchangers are classified in detail based on multiple features, including utilization and construction, methodology.
Keywords: wastewater, heat recovery, energy, heat exchanger
