Water

in the industry due to high degree of water quality with respect to hardness of the substance. With decreasing amount of hardness - the property that comes to the value contained in solid solution - which in this case are the salts dissolved, the water is present for consumption of lighter boiler or manufacturing medicines requiring purified water. In order to optimize the treatment of purifying water, it uses the application of ionized resin tanks where water entered undergoes chemical…

Reúso; Efluente. ABSTRACT With the development of industrial activity over the years increased environmental problems, as the textile sector needs a lot of water for its production process and increasing the rigor of the laws and regulations, besides the high cost of water collection and subsequent treatment of the effluent. Therefore the aim of this work was to verify the possibility of reuse of the effluent in industry X. Therefore this work was to…

por vez. III. ABSTRACT The home-made Water Treatment Plant (WTP) is a project that uses simple concepts of chemistry and physics. Four water gallons of 10L are used, this way each one represent, in simplified way, stages from a real WTP. This gallons are placed vertically so that the gravity makes the water pass from a gallon to the next one, without the needing of bombs. Between the gallons valves were placed to enable to prevent the passage of water, when it becomes necessary. The…

do rio. Câmeras de vídeo, radares e sonares informam a localização do lixo. Hoje, existem 125 espécies de peixes no Tâmisa e mais de 400 espécies de invertebrados. Mesmo com os sinais de que a revitalização das águas do Tâmisa deu certo, a Thames Water, empresa de saneamento londrina, mantém um alto investimento no tratamento da água e no sistema de esgotos. A guerra contra a poluição deve ser constante. A reforma das estações de tratamento, fiscalização de despejo, tratamento de todo…

ABSTRACT: The dependence of people on water presupposes that the later should have physical, chemical and radioactive characteristics, besides biological one, that would not cause any health-threatening factors. Water from Water Treatments Stations should undergo treatment so that it would become drinkable. Disinfection aims at removing and inactivating pathogenic microorganisms. Chlorine in its several forms is one of the most used disinfectants in the treatment of water worldwide due…

determined from Table A-13E by interpolation but the values will not be as accurate as those by EES. The change in the enthalpy across the turbine is then Δh = h2 − h1 = 106.95 − 129.95 = −23.0 Btu/lbm 7-36E A piston-cylinder device that is filled with water is heated. The total entropy change is to be determined. Analysis The initial specific volume is v1 = V1 m = 2.5 ft 3 = 1.25 ft 3 /lbm 2 lbm which is between vf and vg for 300 psia. The initial quality and the…

433/97 também denominada Lei das Águas. ABSTRACT Water resources are surface water or groundwater available for any kind of use of region or basin. Water resources can be seen in many ways, we must always see if there is a relationship with agriculture. Land and groundwater are the main reservoirs of fresh water available for humans (approximately 60% of the world's main source of water or underground aquifers). At the outset, since water is a renewable resource would always be…
