Abstract:

The activated sludge process efficiency depends on separation of microbial cells from treated wastewater. Separation can fail due to a number of problems. One of these problems is sludge bulking which is non-settling situation of biomass. Former studies showed that phosphorus deficiency caused filamentous sludge bulking with increasing magnesium ion concentrations. The main objectives of this study are to find out the effect of magnesium ions on sludge properties in phosphorus deficient medium and to determine if there is any bulking. Three different concentrations of magnesium (0.5, 5, 15 meq

Abstract:

The report formulates the experiments conducted to remove phosphorus from the return sludge wastewater subjected to side-stream hydrolysis. The experiments are conducted using the wastewater from the outlet of side-stream hydrolysis and is tested in a laboratory at the Duvbackens wastewater treatment plant in Gävle. Chemical precipitation is used in the experiments and displays remarkable results using magnesium chloride and calcium chloride as the precipitants. A successful removal rate of 79-99% is achieved through this method. The phosphate phosphorus content is chosen to be the criterion f

Abstract:

Activated sludge systems are the most widely used biological wastewater treatment processes all over the world. The main working principles of an activated sludge system are the oxidation of biologically degradable wastes by microorganisms and the subsequent separation of the newly formed biomass from the treated effluent. Separation by settling is the most troublesome stage of an activated sludge process. A decrease in the efficiency of the separation of microbial biomass from the treated effluent causes a decrease in the overall efficiency of the treatment plant. The efficiency of the separa

Prescribed fire use in Virginia and West Virginia has increased over the past ten years as forest managers on public lands have increasingly used prescribed fire to meet management goals. These goals include hazardous fuel reduction, wildlife habitat restoration and management, and control of less desired vegetation.

In this study, we addressed wildland fire's effects on water, vegetation, and soil resources in the central Appalachian Region. Moreover, the long-term efficacy of various types of timber ha

Magnesium (Mg) and its alloys are being used as structural components in industries because of their high strength-to-weight ratio and relatively high stiffness. A shortcoming of Mg alloys is poor corrosion and wear resistance that have hindered its widespread applications. Corrosion can be minimized by using high purity alloys, rapid solidification, and surface treatment or coatings. Of these techniques, electroless nickelphosphorus (EN) coating is one of the most effective methods to combat the problems.

博士<br>國立成功大學<br>資源工程學系碩博士班<br>97<br>Blue light emitting diode (LED) chip coated with a yellow yttrium aluminum garnet doped with cerium ions (YAG:Ce) phosphor has led to the commercial production of white LED. The advantages of good reliability, simple preparation, low cost and so on are the reasons why this YAG product has been popular on the market for a long time. This dissertation not only investigates the spherical YAG:Ce and YAG:Tb (terbium) phosphors granulated by a spray-drying method, but also studies the host transition from YAG to TbAG (terbium aluminum garnet) synthesized with the

碩士<br>國立臺北科技大學<br>化學工程研究所<br>98<br>In this paper, we used the ethylene glycol monobutyl ether, (EGMBE) as the modifier, dichloromethane as the diluents, and D2EHPA as the extractant to prepare the extractant-impregnated resin, EIR. We examined the effects of various parameters, such as the initial concentration of the metal ions, the amount of EIR and the operating temperature. We also investigated the adsorption of Magnesium ions on EIR.

Abstract:

Sheep breeding is nowadays a developing branch of agriculture again. There is a lot of different breed and they react distinctly on the same conditions of the enviroment. Sheep of breeds charollais, suffolk, šumavská ovce and valaška bred in similar conditions were observed in spring and autumn of years 2007 and 2008. In these seasons were taking blood samples (from {$\pm$}7{--}24) ewes and lambs and were analyzed in hematology laboratory. There were determined haemoglobin level, haematocrit indicator, erytrocytes and leucocytes levels, glucose, cholesterol, triglycerides levels, urea and plas
