ABSTRACT The several uses of water, its unsuitable exploitation and the pressure from urban centers contributed meaningfully in the degradation and pollution of water resources, affecting their availability and quality. The sustainable sanitation is an alternative to mitigate this reality, in which is priority to reduce the consumption of potable water to transport human excreta and allocation of water with better quality for the noblest uses. Nowadays, waste water reuses systems are widely used

IN COOLING WATER SYSTEMS OPERATING WITH HIGH CONCENTRATION CYCLES Eduardo Alencar de Souza February/2007 Advisor: José Antônio da Cunha Ponciano Gomes Department: Metallurgical Engineering and Materials Science In this work the behavior of an inhibitors mixture containing 6:4:1:1 in ratio 2- (MoO4 / HEDP / PO43- / Zn2+) in the presence of high concentration cycles (1050 ppm Cl- e 450 ppm Ca2+) cooling water was studied. The increase of concentration cycles in cooling water…

min. Heat-resistant grades can be used for short periods at temperatures to 110°C in light load applications. Low moisture absorption contributes to the dimensional stability of molded ABS parts. Molded ABS parts are almost completely unaffected by water, salts, most inorganic acids, food acids, and alkalies, but much depends on time, temperature, and especially stress level. Food and Drug Administration (FDA) acceptance depends to some extent on the pigmentation system used. The resins…

presents a study of the use of sugarcane bagasse as an alternative source of cellulose, for obtaining cellulose triacetate (CTA) and consequently production of membranes for use in controlled release system (CRS) of the drugs naproxen (water insoluble) and doxycycline (water soluble). The sugarcane bagasse was delignified from three successive reflux of a mixture 80/20 (v/v) nitric acid concentrated and ethanol, subsequently treated in NaOH solution. From the analysis of Klason Lignin,…
