The Importance Of Chlorinating Water For The Purpose Purifying It

We conducted a Free Available Chlorine (FAC), Chloramines (Total Chlorine) test on the portable water we received from the pier services prior to our initial transfer of water and our test indicated the following:

I was fascinated by this experiment that we recently did on water contamination, tap water versus expensive bottled water. Our water is tap well water. While exploring the topic futher, our research area took place on our kitchen counter where we observed how the test chemicals reacted with the tap water versus the bottled waters. We needed to follow the directions thoroughly, so we got accurate results. We started with test strips of ammonia: all three glasses of water contained: 0 mg/L of ammonia, 0 mg/L of chloride. The 4 in 1 showed: Tap water; 0 mg/L, total alkalinity; 10.0 of total chlorine, 120 mg/L of total hardness. The Dasani revealed 40 mg/L of total alkalinity, 0 mg/L of total chlorine, 0 mg/L of total hardness. The Fiji

Conclusion and evaluation Investigating the effect of pH on the concentration of chloramines and evaluating their effects in pool water was the aim of this experiment and research. With the data collected and processed, I can now discuss the extent of influence of pH in chloramine treatment as well as the success of this experiment. The experiment prove that pH is a very crucial agent in cleaning of a pool. A pound for pound efficiency is almost guaranteed for chlorine administered in any form if proper pH management is considered. Looking at the dissociation of hypochlorous acid under different pH values, it can be proven that the lower the pH the better the efficacy of chlorine.

The U.S. Environmental Protection Agency (EPA) strictly regulates the levels of health-risking contaminants that are allowed in drinking water, to try and ensure that tap water, used for drinking, meets certain standards. Chlorine is used by most water treatment facilities in the United States, to clean the water drinking supplies. The EPA has determined that chlorine levels of four parts per million, or less, are safe for human consumption. While, the chlorination of drinking water has been credited with increasing life expectancy, and being one of our nation’s major public health achievements, there have been studies, that link chlorination to higher occurrences of some types of cancer, and other health problems, including eczema, heart disease, asthma, and higher miscarriage rates. When chlorine interacts with various organic compounds in the fresh water, trihalomethanes (THMs) are produced, which are environmental pollutants, and carcinogenic. When THMS are ingested, they foster the growth of free radicals, which are known to harm or destroy vital body

which are directly transmitted through drinking water which lack adequate sanitation, these diseases can be prevented with appropriate water treatment and proper sanitation. Disinfection by chlorine is important step in drinking water treatment to prevent pathogens breakthrough into water supply systems, Chlorine, the most common disinfectant in Iraq, it is effective in killing most pathogenic bacteria and viruses, it is a strong oxidant that rapidly kills many harmful microorganisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use. In aqueous environments, uncombined chlorine, in the form of unionized hypochlorous acid (HOCl), is an extremely potent bactericidal and virucidal agent, even at concentrations

The Manufacturing Chemists Association (MCA) is the oldest chemical trade organization. It represents 90% of the production capacity of basic industrial chemicals in the U.S.. MCA cites “many people define a water pollutant as anything put into water which was not there in its natural state” (Lantz para 1). Although it might not seem contaminated even natural spring water is impure. Cancer,

Chlorine is a commonly known element highly notable for its use as a sanitizer in most swimming pools. When poured into water, chlorine breaks down into various smaller chemicals, including hypochlorous acid, that are efficient in killing different bacterias and viruses. Acids invade bacterium and destroy the proteins’ ability to function, causing the cell to die.

Would you be surprised to learn that Chlorine is physically added to your tap water? Liquid chlorine is actually added in order to kill bacteria despite the fact that cryptosporidium is extremely resistant to it. Chlorine also happens to be

In the past, we believed that a filter would sift out any and all impurities in a given water source. We didn't realize that separate filters were needed for different things. This lab exemplified how a filter works and what type of things can help to clean water. We believe that had we spent more time constructing the bottle filter, we would have received more positive results. To conclude, in some cases, the filters tested were able to clean certain contaminants from contaminated water. In the more polluted sources, it was evident that not all pollution was filtered out. It is highly unadvisable for anyone to conduct this experiment intent of drinking the

The commodification of water throughout history has had substantial impacts the way we live our lives and the health of our nation. Initially effluents from towns, various types of mills, and tanneries were channeled to the nearest waterway to be carried downstream and away from the pollution source. This theory of "dilution is the solution to pollution" worked for a little while but as population grew and the demand for freshwater for humans consumption increased as well Americans learn quickly that this theory was incorrect.

In source 5 we learned that chlorine tablets kill pathogens and deactivate bacteria, viruses, and parasitic protozoans in contaminated water to make it safe to drink. If you drink contaminated water, many of the contaminants that can be found in water could kill you. After putting a chlorine tablet in a container of water you should let it sit for 30 minutes and make sure to close the container or the chlorine will evaporate, but even after 30 minutes the water might have an unpleasant taste depending on the type of chlorine tablet you are using.

Water is the fundamental source of life on earth. Although water has one of the most unique properties it is the most abundant compound in the biosphere. It is the only substance known that exists naturally in its 3 stages, solid, liquid and gas and has the highest number of possible crystal structures. The formula for water is H20, it is composed of two hydrogen atoms and one oxygen atom, and because water has a net dipole the shape of the water is bent.

Although the state of America’s water infrastructure is of great concern, the types of chemicals found in America’s tap water are equally as frightening. The passage of the Water Act in 1972 prevents the direct dumping of hazardous chemicals directly into waterways, and helps regulate quality standards of water. However, the Clean Water Act is has no jurisdiction on regulating indirect dumping of chemicals that integrates into water supplies. Pesticides and prescription drugs are the greatest cause for concern of indirect containments in America’s water supply (Olsen). An abundance of the harmful chemicals found in liquefied animals feces, used in large dairy states, have percolated into drinking wells that have caused serious infections (Duhigg). However, more harmful containments are infiltrating water supplies. Such containments include

Water disinfection means eliminating or inactivate of growth and reproduction in pathogenic microorganisms by creating cell wall corrosion in the cells of microorganisms, or changes in cell permeability. From the water treatment process, disinfection is a sufficient and the crucial process in order to inactivate bacteria, viruses and pathogenic organisms that can waterborne diseases to downstream users and the environment (USEPA, 1999). There are three most common methods of disinfection in the U.S., which are Chlorination, Ozonation, and ultraviolet (UV) disinfection. “Chlorine, the most widely used disinfectant for municipal wastewater, destroys target organisms by oxidation of cellular material. Ozone is a strong oxidizing agent that is an unstable gas that is generated by an electrical discharge through dry air or pure oxygen. Finally UV radiation generated by sunlight, tanning lamp, black lights, and electrical discharge through mercury vapor, penetrates the genetic material of microorganisms and retards their ability to reproduce” (USEPA, N.D.). One of the popular disinfection methods in water treatment is the Ultraviolet (UV) disinfection. The ultraviolet (UV) disinfection is a physical disinfection of water. This paper would provide a broadly definition of UV disinfection and its purpose in water treatment. Also, this paper will provide the advantages and disadvantages of using the advance technology over the common technology in water treatment.

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration,sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such asflocculation and chlorination and the use of electromagnetic radiation such as ultraviolet
