Name: Professor: Course: Date: Water Treatment, Desalination Water is an essential natural resource with a wide range of functions. Water treatment is a process aimed at purifying water for either consumption by human beings and animals or for irrigation. Several processes are applied during water treatment. Desalination is a process of removing salt and other chemicals from sea water. The process is complex with varied economic benefits, environmental and health impacts, and social impact

For rice husk, The TG and DTG curves in Fig. 2 and 3 shows that there are three main peaks during the combustion process and each one has a clear burnout temperature. The first peak at the temperature of 100℃ is observed due to the evaporation of moisture and volatilization of small organic molecules deposited onto rice husk surfaces. The second peak with a maximum weight loss rate of 12.56%/min at temperature of 296℃results from continuous evaporation of moisture and loss of volatiles contained

concentration first results in the formation of mixed choro-bromo species to fully brominated ones (Hua et al., 2006). It has been reported that brominated DBPs so formed are more carcinogenic as compared to the chlorinated ones (Uyak & Toroz, 2007). Water and wastewater treatment processes remove organic carbon but bromide ion is quite resistant to be removed by these and hence ultimately ratio of bromide ion to total organic carbon (TOC) increases. This increases the fraction of brominated DBPs (Roccaro

The popularity and rise in applications of electronic devices may be a cause of electromagnetic (EM) environmental pollution [1-4]. While EM fields are needed for many electrical instruments to operate, they can wreak havoc on the operation of other nearby electrical devices. In addition, some studies exhibit that EM radiation can harm human health [5-7]. A simple solution to overcome these problems is to provide EM shielding via coating the sensitive electronics parts or EM radiation sources by

Abstract— The pump is one the most common machine in all industries, whether its small scale or heavy industries. In the present scenario of energy crisis, it would be advisable to conserve, even the minute proportion of energy. In the centrifugal pump, the inefficiency is mainly due to the hydraulic losses in its various components. In this phase, mathematical analysis is done to predict the performance characteristics curve of the single stage centrifugal pump. This methodology is based on the

The water from this process can then be used to produce oxygen and extra hydrogen through an electrolysis reaction. The oxygen produced can be used for breathing in the Mars atmosphere while the hydrogen can be combined with either the crew’s expended CO2 or atmospheric CO2 in order to produce more water. This is the basis of the Sabatier Reaction, which is the most credible way for space dwellers to receive the oxygen required for life in space.3,4 The water produced from the Sabatier

Salt What is it exactly? Salt is the residual left when waters from ancient oceans evaporated in shallow seas or marginal basins. http://www.waterencyclopedia.com/Mi-Oc/Mineral-Resources-from-the-Ocean.html Where is it found or used geographically? It is found in salt mines or in shallow water that is mineral rich. http://en.wikipedia.org/wiki/Salt How is/was it used? Salt is used in many different ways. Salt is used in the seasoning or flavoring of food while it also can be used to preserve
