1. Reason for the process.
Water plays such an important role in our daily lives. 70% of our body is composed of water. 70% of the earth surface is also made up of water, but out of the 70%, only 1/3 of water is consumable. In fact, this amount has been continuously to decrease as more and more industries began to pollute and damage the water. For example, many toxic chemicals may be released into the water thus making the water impure. Such pollutions and damages lead the water to be contaminated and inconsumable as it may cause severe diseases. Water purification can remove all the unnecessary bacteria and viruses from the water that is hazardous for our health. Water purification may also improve the flavor and appearance of water. It removes the unpleasant odor. Therefore, water purification became one of the most useful and popular process used by people all over the world today. It is by far the most recommended and safest water treatment that is commonly used to purify damaged water into consumable water. Water purification provides us with safe, pure and clean water to consume and use.
2. History of the process.
The history of water purification started off in ancient Greek in the 2000B.C. people at the time used to boil water in order to purify it. There were also filtration and straining methods which helped to reduce visible particles and turbidity in water. However, due to the lack of knowledge in the chemical area, almost no process was taken to remove the harmful chemical contaminants. In fact, the purpose of water purification at that time was purely to make it smell and taste better. They believed if the water taste good to the mouth, it must be safe, clean and healthy. Therefore the Gr...

6. Effects on local area (environmental and social).
Chemicals and impurities removed from water may not be disposed properly thus polluting the environment. A sheet volume of discarded filters may add up to landfill mass. The system itself may take up large amount of spaces and cause lots of noises and destructions. There may also be chemical or wastewater spills if not handled properly.
7. Role of the Chemist.
.
Chemist performs laboratory and field tests to monitor the environment and investigate sources of pollutions. A job as a water purification chemist falls under the broader career category of environmental science and protections. Water purification chemists must be comfortable working in a laboratory setting as well as in the field, and they must be comfortable communicating their findings and opinions to others.
The effects of the effluent discharge in the water body may have negative effects on the natural
Disinfection is applied in water as well as wastewater treatment as a finishing step so as to destroy pathogens but the cause of concern regarding the disinfection process is the formation of disinfection byproducts (DBPs). Natural organic matter (NOM) in water has been considered as the predominant DBP precursors. Disinfectants are powerful oxidants that oxidize the organic matter present in water forming DBPs. Chlorine, ozone, chlorine dioxide, and chloramines are the most common disinfectants used nowadays and each produces its own suite of chemical DBPs in finished drinking water (Richardson, 2003). DBPs so formed pose a threat to human health because of their potential to cause cancer and reproductive/developmental effects. Most developed nations have regulated concentration of DBPs so as to minimize exposure to potentially harmful DBPs while maintaining adequate disinfection and control of targeted
Drinking water is one of our basic needs in order to survive, therefore the water that we drink and cook with must be of a high quality, and filtered of any harmful contaminants.
As the bottled water becomes more popular, people prefer to drink bottle water over tap water. According to them, it has a better quality and taste. Unfortunately, people are being fooled by the water industries. The “purified” water, as its label, comes from municipal reserves. This research will discuss:
Three Medical Doctors wrote the book, The Water We Drink: Water Quality and Its Effects on Health. Their names are Joshua I. Barzilay, M.D., Winkler G. Weinberg, M.D., and J. William Eley, M.D. In order to put the issue of drinking water quality and its effects on health into perspective, the book is divided into three parts. It first reviews the history of water, disease, and sanitation. The next section deals with health issues. At the conclusion of the book are chapters regarding bottled water and methods of purification. The intent of the book is to educate consumers.
Water is one of the most vital components of human life. It is a necessity, a precious resource that humans need to live, that is taken for granted every day. There is no possible way for life to be sustained on Earth without water – it just cannot happen. The human body itself is composed of almost eighty percent water: almost 95 percent of the human brain is water. It is common knowledge that pure water is the best water – for humans, and for plants and animals. Regardless of this piece of knowledge, humans still find ways to disregard the sanctity of pure water and instead, pollute it. The right to water is not officially a human right. However, because “water is a basic need for human development, health, and well-being… it is an internationally accepted human right” (Thompson 3). Water contamination is an epidemic that is so common these days that it is no longer shocking to even hear that water is contaminated. Water contamination negatively effects water that is used on a daily basis. Continuing on in this way will eventually lead to contamination that will make the existence of clean water impossible.
It’s no mystery that having clean water is a fundamental element to living in a prosperous society and one of the few things essential for human survival. Water not only sustains our health, but is required in making everything from electronics to clothes. Clean water may seem as ordinary as putting on your shoes, but it’s a daily party of our life that’s being threatened.
This is because only a small part of the population, particularly in developing countries, have access to water of acceptable quality. It is estimated that in some countries only 20% of the rural population has water of satisfactory quality. Based on these statistics, it is clear the urgent need for awareness about caring for water use. Almost without realizing it, we are seriously jeopardizing this essential resource, not for us but for our children's children and their generations, aware that in other parts o...
There are 80 countries that have been suffering from a lack of clean water, and two billion people lack access to freshwater, especially South Africa (Alois). This area of countries is the driest in the world - Sudan, Ethiopia, Egypt and so on. Like in the book A Long Walk to Water by Linda Sue Park, Nya, who lives in Sudan, has been lacking clean water. She has to find water every day for her family. Luckily, Nya got help from Salva who used to live in Sudan and came back from America to build the water system for her village. However, there are still many people around the world that have been suffering to find clean water for basic use. There are many factors that cause a lack of clean water around the world: geography of countries, deforestation,
Human activity can influence the quality of our water in the environment. Sewage is a major problem because billions of people are disposing of waste. Although, there has been an improvement on being able to obtain clean water, yet little has been done on upgrading the global sanitation. Sewage disposal has an immediate effect on people’s environment and leads to water related illnesses such as; diarrhea and cholera.

Having clean water to drink means that water must have microbial, chemical and physical characteristics that meet WHO guidelines or national standards on drinking water quality. Around 780 million people in the world don’t have access to clean drinking water (Millions Lack Safe Water). More than 3.4 million people die each year from water, sanitation, and hygiene-related causes. Nearly all deaths, 99 percent, occur in developing countries. Around the world, diseases in unclean water kill about 1,400 children every day (Clean Drinking Water). There are many organizations that raise money in order to help develop ways or create ways for people to obtain clean drinking water. However, many people are unaware that this is even a problem in other countries because we take clean water for granted.
The consumption of contaminated water can be dangerous for health reasons and several people have passed away from these water-borne diseases. Some of these diseases include Cholera, Typhoid, Dysentery, Giardiasis, and Malaria. These unfortunate diseases are currently the cause of numerous deaths, especially in small children. The availability of clean water can prevent many problems in low-income communities. The available resources for clean water are very rare, so these water sources need to pass through a process of water sanitation in order to just be sustainable to drink, “The world’s surface is made up of approximately 80% water, which is an indestructible substance.
Because water can float and be carried by the wind, it can cause harm to unsuspecting creatures hundreds of feet from where it was originally dumped. Such waste includes bags, bottles, cups, straws, cup lids, utensils, six pack holders, cling wrap, fishing line, bait bags, and floats. The second highest cause of water pollution is ship waste. Ships used to take much garbage with them on their ships and dump them. This was very common until the government took action.
...or lakes (Weber 2). When people just dump waste products instead of recycling, it is a misuse of the soil and can contribute to serious health conditions in animals, plants and humans.
