THE USE OF THE A.G.P. TEST FOR DETERMINING THE PHYTOPLANKTON PRODUCTION AND DISTRIBUTION IN THE THERMALLY STRATIFIED RESERVOIRS: THE CASE OF YONGDAM RESERVOIR IN KOREA
Environmental Engineering and Management JournalVol. 10Nr. 11
Abstract: The paper focuses on eutrophication due to nutrients load into a reservoir. A thermally stratified reservoir water body is divided in vertical layers and horizontal zones according to water temperature and depth. The layers show different compositions of limiting nutrient because of the density of flow and due to inhabitants on the bottom of the reservoir exposed to sunlight. The bioassay for algal growth potential test (AGPT) is the most direct and effective way to determine a limitin...

DRINKING WATER QUALITY IN WATER-SUPPLY NETWORKS
Environmental Engineering and Management JournalVol. 10Nr. 11
Abstract:The paper describes some studies on the influence of water flow rates through water-supply networks on drinking water quality. Water residence time in pipelines for more than seven days in buried pipes and two days in above-ground pipes promotes the development of biochemical systems when the flow rates are low and very low having detrimental consequences on drinking water quality. These shortcomings are due to the residual chlorine decrease below the allowed technical limits (0.5 m/s) ...

IMPROVEMENT OF A NON ENERGY-CONSUMING SYSTEM: A GAMMA STIRLING ENGINE
Environmental Engineering and Management JournalVol. 15Nr. 1
In this paper, the classical adiabatic model was chosen. The assumption of perfect gas working fluid was replaced by that of a real gas working fluid. This last assumption was defined by the van der Waals state equation. A Gamma type Stirling engine functioning with a maximum filling pressure of 10 bars was used to carry out experiments. Both theoretical models: the Perfect Gas Adiabatic Model (PGAM) and the Real Gas Adiabatic Model (RGAM) were applied to the Gamma Stirling engine. The influ...
