Chemical Coagulation vs Electrocoagulation for Groundwater Treatment

Water contamination is vastly becoming an alarming issue across the world. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution (www.nrdc.org). Clean and plentiful water is the cornerstone of prosperous communities. Yet as we enter the 21st century, swelling demand and changing climate patterns are

Not only is pollution the cause of the death of many organisms essential to ecological balance, but human drinking water has also been affected.

The impending crisis in India would be a good opportunity to study the effects of the poison and perhaps show the rest of the world the importance of awareness and spark them into action. Arsenic is a destructive element that must be contained and controlled. Up until now, few individuals know much about the impacts of arsenic. This is shocking since it is a element that will undoubtedly influence the lives of many individuals on this planet in the following couple of

Imagine you're drinking a cup of water and every single drop is poison. This could be happening to you. 50% of the United States have lead in their drinking water. This is because of lead based pipes. Lead based pipes have been leaching lead into water which connects to drinking water. It can also be because of the state's water utilities that might have lead in their water. ( EPA's safe drinking water information system database reports, three, 2016 by Isabella DC, USA Today) says Lead can cause brain damage, cancer, seizures, hearing loss, learning disabilities, and more!

There is a water crisis which faces many parts of the world and it is a threat to survival of human beings since humans are primarily dependent on water. Shortage in drinking water is beginning to show its effects in first world countries, but is a current major problem facing lesser developed countries which have not taken drastic steps to harvest water and purify it to make it safe for human consumption. In developed countries the population growth has strained available water resources and stretched the ability of governments and private firms to provide safe drinking water to the vast majority of the population. Seventy one percent of

illegal level of bacterial growth. This study also found high levels as high as 13 parts per billion of arsenic tap water is only allowed to have 5 parts per billion.

You may well know that aluminium, along with a number of other contaminants, can be found in your drinking water but did you know why it’s in your drinking water? More importantly, do you know if it’s even safe? Aluminium is already present in our soil and as a result will be found in untreated sources of drinking water such as wells. On top of this, aluminium compounds are also used to help remove any impurities at water treatment works. Aluminium happens to be very useful in the battle against cloudiness and bacterial content before the water enters the final stages of disinfection and treatment however, as a result of its use a residual amount remains in the water supply. The legal standard for

Although municipal water can contain a vast array of contaminants, several continued to repeatedly show up in water of the cities studied. Among the most frequently found contaminants were Arsenic, mentioned earlier, and other toxic chemicals such as radon, the rocket fuel perchlorate and other carcinogens, which may cause skin problems, birth defects, reproductive problems and even cancer. High Volumes of Lead were found, which enters the drinking water supplies from the corrosion of old pipes and

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

There is a huge amount of people who do not have access to clean drinking water around the world. This highly affects their health and growth. Forty percent of Africa’s population and fifty-three percent of Asia’s population, lack access to clean drinking water. The access to clean water is a complicated issue, often influenced by politics, economics, climate, and social structure.

Water is a critical source that is utilized by most living things on Earth to support it ways of live. The usage of water ranges from basic household needs to agricultural purposes. Water is one of the resources on the Earth that is becoming more and more scarce and the water available for usage is being further contaminated by pollution causing sickness and death.(World Health Organization).Countries are experiencing droughts affecting the water supply needed to maintain irrigation, thermoelectric power, and public supply. The definition of water pollution is the result of when too many toxic materials are present, in which negatively impact the water to be unsafe for its intended purpose, which may be drinking to industrial processes

The second step of water treatment process is aeration. At the aerator, raw water is mixed with air. The aeration process helps to provide oxygen to the raw water which is needed for the oxidation process of dissolved iron and manganese in order for it to precipitate and therefore enables its removal through filtration (SAJ Holdings Sdn Bhd., n.d.). Wormleaton and Tsang (2000) stated that for water treatment process and also natural streams, it is essential to maintain a high amount of dissolved oxygen. Aeration also provides the escape of dissolved gases, such as carbon dioxide and hydrogen sulphide to reduce the corrosiveness of water, thus controls the tastes and odors of the water (Shun, 2007). Groundwater with high dissolved carbon dioxide levels or high concentrations of iron and manganese commonly require aeration as well as water drawn from reservoirs that is low in dissolved oxygen.

Access to clean water is a basic human right and yet people around the world don’t have that right and they struggle to survive without it. The many uses of clean and potable water include water for drinking to cooking other daily purpose. It is reported that over 1.1 billion people lack access to an improved water resource and three million individuals, and majority of them children, suffer and die from water-related disease. The need to improve water quality and providing clean water should be major project for developed countries like the US and so called “well developed countries”.

The purpose of this report is to propose a solution to the problem of reduced drinking water quality due to chemical pollution. Some bodies of water in the United States are becoming polluted from chemicals and restrictions are needed to protect drinking water quality.

Relevant literature on the internet was searched to find other instances where this type of application or technology may be in use. No corroborating studies or other applications of successful water treatment using an electrode inserted into a pipe were found, except those instances offered by Zeta Rod.
