The Effect Of Chlorine On Water Drinking Water Treatment

Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below.

starts to become poisoned and deformed. People tend to look past such issues because of the misconception that water treatment plants will just filter all the chemicals out easily. Although the treatment systems for our water are highly advanced, they fail to remove all the chemical agents from harmful pharmaceuticals, pesticides, and hazardous waste. The

The chemicals found in water can be dangerous toward our health. We live near the Great Lakes which supplies 20% of the World’s fresh water. It also has chemicals that threaten the life evolving around the fresh water. There are medical drugs that are being introduced to the fresh water lakes. Stuff like antibiotics and steroids. These pharmaceuticals are posing danger for the environment. This could affect the lake life,s growth.

The use of chlorine revolutionized pool sanitation and cleanliness in the early 1900s. While there have been large improvements in the construction of pools since the mid-twentieth century, the products available for sanitation and the policies regarding them remain mostly the same today. Chlorine is excellent at keeping bacteria levels down in pools, but there are still improvements to be made and caution must be used during pool maintenance. Chlorine can cause deterioration of the cornea and respiratory issues, including an increase in asthma among individuals who frequent indoor pools. Additionally, chlorinated water runoff from pools and hot tubs into waterways can be detrimental to wildlife, even at rates as low as 0.011 ppm (Olsen,

Dissolved oxygen (DO) is the oxygen that is dissolved in water. Dissolved oxygen can enter water through either the air or as a plant waste product. From the air, oxygen slowly diffuses across the surface of the water, or can be mixed quickly through aeration. Aeration can be either natural, by wind, rapids of waterfalls, or man-made, from things such as an aquarium pump. DO can also be produced as a by-product of photosynthesis from phytoplankton and other aquatic plants. Dissolved oxygen is an

Chlorine is used in pools in either a gaseous or as sodium or calcium hypochlorite. The chlorine is added to water to help prevent people from getting sick from disease-producing microorganisms. The chlorine that is added and reacts with the organic material and metals in the water is the chlorine demand for the water as it will not be available for any disinfection that keeps people from getting sick while in the pool. The residual test is

Chlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. When chlorine is added to water, chloric acids forms: Cl2+H2O = HOCl + H+ + Cl-. Depending on the pH value, chloric acid partly expires to hypochlorite ions: HOCl = OCl- + H+. Hypochlorous acid (HOCl) and hypochlorite ions (OCl-) will form free chlorine when bound together, and they are primary disinfectants throughout the process. However, the chlorine dosage has to be high enough to reach the breakpoint for a significant amount of chlorine to remain in the water. When passing the breakpoint, the addition of chlorine to the water will only produce free chlorine remains which is essential for disinfection.

These substances, generally referred to as contaminants, can come from a range of sources, including residential, industrial, agricultural, or extraction activities. With the intention of improving national water quality, the federal government tasked the Environmental Protection Agency with setting standards for drinking water supplies as part of the Clean Water Act of 1972. These standards refer to the maximum contaminant levels (MCL) and the secondary maximum contaminant levels (SMCL). The MCL list outlines the most prevalent water pollutants and each of their maximum concentrations that may exist for a source to be considered safe. These contaminants can be classified as microbiological, disinfectants, disinfectant byproducts, inorganic chemicals, organic chemicals, or radionuclides (EPA, 2018). The SMCL outlines a number of non-mandatory guidelines for the proper aesthetics of drinking water. Although a water source may be free of MCL's, many individuals will discontinue their use or file a complaint if their water appears cloudy, tastes, or smells

Based on the results, the hypothesis was not correct. It was hypothesised that the control sample would retain the most chlorine, and light would retain the least, with stabiliser and cover between them. The results gathered were very different, showing cover as the best, retaining 70.2% of the original OCl-, and stabiliser as the worst with only 50.3% of OCl- remaining. The control and light samples were situated between them, with an OCl- retention of 58.6% and 56.1% respectively. This is very different to the expected results, and can only be put down to errors and anomalies, since there is no logical explanation for the control sample to do worse than the covered sample, since it was kept in darkness. However, the general

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.

Few resources are essential to human survival. Access to clean water is the most critical of all. Water is a vital resource responsible for sustaining all life on earth. However, clean water is in short supply, but in high demand in all parts of the world. It is thought that most Americans have access to safe, affordable, clean water right from their taps. However, the media is uncovering the true nature of America’s deteriorating water situation. Americans have reason to be seriously concerned about the state of their drinking water. So what really is on tap in America?

The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese,
