Abstract: Selective precipitation of phosphate from fluoride-containing wastewater was studied using magnesium salts. Wastewater sampled from a semiconductor manufacture was found to contain 936 mg/L of fluoride

Abstract: This investigation considers the thermo-mechanical effects of an asperity traversing at a high speed over a semi-infinite medium with a thin, hard coated surface. The general analytical solution ...

Abstract: The present paper discussed the critical depth, i.e., the depth at which the thermal tensile stress reaches a maximum, caused by the frictional excitation of a fast moving asperity. In the ...

Abstract: Chemical precipitation method utilizing calcium salts has been extensively used to treat fluoride-containing wastewater from semiconductor manufacturers. The major objective of this study was to investigate coagulation-f ...

Abstract: Treatment of chemical mechanical polishing wastewater containing nanosized silica from semiconductor industry by dispersed air flotation was investigated. Very effective removal of particles from wastewater was found when ...

Abstract: This paper discusses the fractal characteristics of the autoregressive moving average (ARMA) model, which has been considered as one of the useful approaches for investigating the random engineering ...

Abstract: Tetramethylammonium hydroxide (TMAH) is widely used in manufacturing thin-film transistor liquid crystal displays (TFT-LCD) and semiconductors. Because of its toxicity and nitrogen content, TMAH-containing wastewater has ...

Abstract: Dual conditioning of activated sludge utilizing polyampholyte (T204) in combination with ferric chloride or cationic polyelectrolyte, polydiallyldimethyl ammonium chloride (PDADMAC) was investigated. Capillary suction time, ...

Abstract: Treatment of fluoride-containing wastewater from the semiconductor industry by dissolved air flotation was investigated. Calcium chloride was added to the wastewater to form calcium fluoride precipitate

Abstract: Predictions of distortion and residual stress for rectangular bars, quenched on one surface, are compared with experimental measurements. The heat flow is unidirectional, and the dominant stress ...
