Bottled water vs. tap water Water is an essential part to human life. We as humans need around eight to twelve cups per day to make up for the fact that throughout normal functions such as breathing and sweating we lose an average of ten cups per day. To make sure that we are healthy and everything runs properly‚ we must make sure we drink the right amount of water (msnbc.com‚ 2004). The one question when thinking about water is what type of water will you drink? The biggest controversy is bottled

reaction temperature by hot product stream. The product stream is cooled to –100 C and in doing it‚ all unreacted ethanol and acetaldehyde are condensed. The out going gaseous stream‚ containing hydrogen mainly‚ is scrubbed with dilute alcohol (alcohol + water) to remove uncondensed products and the undissolved gas. The remaining pure hydrogen (98%) is burnt in stack. The material and energy balance in a plant design is necessary because this fixes the relative flow rates of different flow streams and temperatures

Is tap water in the U.S. safe to drink? Every one knows that we need water to live. Water is very important to human body; it is consider that human body consists on average of 55-60 percent of water (Martino). In the United States there are two different ways of getting potable water‚ the bottle and the tap water. Tap water is cheap and its very accessible‚ many would argue that is not safe to drink it. However‚ tap water in the U.S. is safe due to their public water treatment systems‚ it is
