The Right

The thermal power plant ‘Morava’, with a productive force of 125 MW, is located on the right bank of the River Velika Morava, near the city of Svilajnac, Serbia. This power plant uses coal for production. Ash and slag from the coal are burned and go to a landfill by hydraulic transport. The ratio of the liquid/solid mixture is 10:1. Towards the reduction of water quantity taken from the Velika Morava river for hydraulic transport, it's provided to build a water recirculation system for overflow and drainage water from landfill to power plant. In this paper, the results of the hydraulic study of water balance in landfill is shown. The goal of this study is to assess the water quantity in landfill, which can then be reused for hydraulic transport. For dimensioning of drainage system and overflow building on landfill, it was necessary to perform detailed analysis of rainfall and filtration throw landfill. With results of water quantity in drainage system, and overflow water, all parts of the recirculation system of water, from landfill to power plant, was performed. Also, in this paper are the data of hydraulic transport of mixture of water and ash/slag.

Stocking Rates

Massive production, such as fish growing in water recirculation system, imposes challenges to animals capable of altering their homeostatic balance, and is able to affect their physiological performance. Therefore, the levels of ions and serum enzymes can be used as indicators of fish health. This study aimed to analyze the blood biochemistry profile of hybrid surubim (P. reticulatum X P. corruscans) submitted to different stocking densities in water recirculation system, in two distinct stages of production, from 150 to 400 g (first trial), and 400 to 1000 g (second trial). In the first trial, the five stocking rates were: 27.5, 47.5, 67.5, 87.5 and 107.5 fish/m³ of water. To obtain these densities, it was used 11, 19, 27, 35 and 43 fish per tank, respectively. In the second trial, five stocking rates were: 10, 20, 30, 40 and 50 fish/m³ of water. To obtain these densities we used 4, 8, 12, 16 and 20 fish per tank, respectively. The concentrations of glucose, cholesterol, triglycerides, urea, creatinine, alkaline phosphatase (ALP), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), calcium, phosphorus, potassium and magnesium were obtained. Only urea concentrations in first trial and ALP and AST concentrations in second trial were influenced by stocking density, presenting a significant difference between groups. Thus, in both trials the hybrid fish studied maintained homeostasis when reared in different stocking densities.
