The First Experiments Of Water Treatment

The Romans, as we now understand, had a slight fixation with aqueducts and baths, to keep their royal family hygienectically clean, as well as appealing, and Rome’s citizen’s hygiene up-to date; kind of hygiene freaks, they were. However, Because of this, plumbing became a profession in its own sense, and the ancient plumber became a trade that would be used, literally around the world. Indoor plumbing was not for everyone, only most wealthy could afford it, and they were charged for the use of public water, and the network that fed the water with a fee based on the size of each pipe they used (History of

Abstract: In this lab, water was added into a test tube. Then, a pH-indicator called phenolftaleine was added to the water. The solution was mixed. Then, gasoline was added to the mixture. Gasoline is less dense than water, so the gasoline floated on top of the water. In addition, gasoline is a non-polar molecule and water is a polar molecule, which caused them not to mix. A small piece of sodium was dropped into the test tube. As soon as the sodium touched the water, it floated back up to the top, fizzing. Once at the top, it fell down and as soon as it touched the water again, it “jumped”. The more the sodium touched the water, the more the water turned pink (due to the pH indicator saying it was a basic solution). Sodium reacts with water, that’s the reason why it would jump up after touching it. The fizzing was hydrogen bubbles being released, and the bubbles had an upward force that was enough to lift up the small piece of sodium. Introduction: Clearly written introduction with a summary of the demonstration, a discussion of the materials used, and a brief summary of the chemistry behind the observations. Chemical equations are included as part of the explanations. Water was placed in a test tube. Then, a couple drops of phenolftaleine was placed in the test tube. Then, some gasoline was poured in the test tube. After having the test tube ready, a small piece of sodium is dropped into the test tube. When the sodium was dropped, the sodium bounced off the water. When the

The beautiful town of Stillwater is located on the St. Croix river in the St. Croix River Valley and is known as the Birthplace of Minnesota. The early days of Stillwater were uncertain and uneasy as the land was fought over for many years. The coveted land transitioned from being part of Wisconsin territory to being included in Washington county in 1938. All the while, lumbering interests drew many to the area and white settlers took up residence in Stillwater. One former soldier, Indian trader, Justice of the Peace and promoter, Joseph Renshaw Brown had been in the area since 1820. He had set up a store and farm at Grey Cloud Island and kept a warehouse at the head of Lake St. Croix to supply upriver fur trading operations. This warehouse, which was located where North Stillwater stands today, grew into a small village that he called “Dacotah”. In 1840 the first ferry was licensed to operate across the St. Croix.

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

One of the biggest challenges of polluted third world countries is the lack of suitable drinking water. However, a woman named Theresa Dankovich created a water purification system called The Drinkable Book. The book has 25 pages of silver nanoparticles which releases silver ions that neutralize disease. The pages were tested in five different countries, and reportedly eliminated almost all of the bacteria.

Clean water supply is essential in establishing and maintaining a healthy community. There are two sources of water supply which are the surface water and ground water. Most natural waters are not suitable for consumption as it is contaminated by pathogens and also natural chemicals and minerals. In addition, as a city grew, wastes from human activities contaminate most of the water supplies. Water treatment plays an important role to properly treat a contaminated source of water supply in order to protect the health of consumers. Water treatment process is defined as a process of eliminating pollutants from untreated water to produce a biologically and chemically risk-free water, which is both potable and palatable for human consumption

The disposal of untreated wastewater coming from the industries into the water bodies will pollute the water bodies because of its high concentrations. So, the wastewater produced from the industry should be treated properly to meet the permissible limits given by central and state pollution control boards. Therefore it is necessary to treat the wastewater properly with the help of an appropriate treatment plant. However, the treatment plant even though properly planned may not work satisfactory because of several reasons. Hence, it is essential to evaluate the treatment plant considering individual treatment unit in the entire treatment flow. In the present work emphasis has been given to the study of the performance of treatment facilities because of its importance in the conventional treatment of wastewater. Hence, the literature review related to the evaluation of the entire treatment process along with biological treatment process particularly suspended growth process Activated Sludge Process (ASP), attached growth process Trickling Filter (TF) and a combination of the both suspended and attached growth process Hybrid Reactor (HR) is presented in the following sections of this chapter.
