Glina Station is a project for the treatment of wastewater from the sewerage of Bucharest. The sewerage of the entire city has always flowed into the Dambovita River. Currently, only partially Stage I is carried out, through which the mechanical treatment of about 60% of the city's wastewater is carried out. The paper presents a solution for biological pretreatment of wastewater to validate the use of ultraviolet waves for biological disinfection but also for the treatment of specific non-synthetic pollutants from...

Unfortunately, soil is a non-renewable resource that fulfills several vital functions such as food/biomass production, storage, filtration and transformation of mineral or biological substances, source of biodiversity and habitats, etc. Due to the development of industrial activities outside the localities, in many areas the soil is degraded. Among these degradation processes can be mentioned degradation of organic matter, contamination, soli salting, and erosion. This paper is dedicated to the presentation of the...

Within the thermal power plants there are many places where the personnel work inimproper conditions. Depending on the concentration and toxicity of gases, duration ofexposure for the personnel, the air can have harmful effects. Currently, several specificmeasures to limit toxic gases have been introduced in the thermal energy system. Thispaper presents as example the situation in Borzesti thermal power plant, throughmodern methods of analysis, by identification and monitoring the physical and chemicalproperties o...

Lakes on the Black Sea coast are the direct result of soil erosion and marine or hydrographic accumulations, consequence of the specific evolution of the nearby sea basin. They depend on the variations in groundwater levels, rainfall or other hydraulic surface sources. In recent decades, as a result of many small, local earthquakes, some deep currents have appeared. Lakes as origins, are of fluvial-marine estuary, lagoons or artificial. Many of them are tourist attractions, due to the specific microclimate establi...

The Bistrita River was the first river harnessed for hydropower purposes in Romania, starting with 1960. Currently, on this river, 29 hydropower plants with different capacities are functioning, producing about 10% of the entire Romanian electric energy from hydro. Many of them were realized in series, in cascade. In the present paper, the area of Pangarati, Vaduri, Batca Doamnei, and Reconstructia hydropower lakes was analyzed. Of these, three are Nature Reservations, Nature 2000, RAMSAR sites. The lakes being re...

In the last decades in Romanian forests, a massive phenomenon of uncontrolled cut trees was observed, leading to a new environmental problem. In these conditions, the solar radiation affects the seedlings of some tree species as the beech and oak, and generally the entire life from these forests. In the last 5-6 years, a supplementary massive invasion of the white mistletoe was observed, especially associated with the silver fir and beech. The main objective of this paper is to associate the effects of the solar r...
