Chemical Disinfection Methods

Improved Essays
It is vital to reduce contaminates and decrease the risk of microbes in drinking water. This process is accomplished through water disinfection. This procedure can be done though several methods; however, chlorine and chloramine are the most frequently used forms of chemical disinfection (Serrano, Silva, & Gallego, 2011). When this process is utilized, there is an increased risk in the release of unwanted by-products can cause severe health risk. The use of chemical disinfection methods, results in the creation of disinfection by-products through the interaction of the disinfectants with natural organic matter (NOM) (Bougeard, Goslan, Jefferson, Bruce, and Parsons, 2010). Due to the minute amounts of the disinfectant by-products, a reliable …show more content…
There is an increased threat of health risk due to the high amounts of microbes in un-disinfected water (Schoeny, 2010). Though there are many forms of cleaning methods currently in use, chemical disinfection is the prevalent method. Two commonly used methods of disinfection are chlorine and chloramine. Chlorine is distributed into drinking water as chlorine dioxide gas whereas chloramine is the product of ammonia added to already chlorinated water (Bougeard et al., 2010). When these chemicals are added to drinking water, disinfection by-products are produced as an undesirable effect. Disinfection by-products results in a negative impact to the environment along with public health due to their toxicity and perseverance (Chary, Nallanthigal, and Fernandez-Alba, …show more content…
(2009), stated in their conclusion that facilities that used chloramination meet European standards while facilities that used chlorine found it more difficult to meet the maximum contaminant limit. Regarding chlorine, chloramine, and THM4 formation, the researchers’ state it is vital to reduce contaminates and decrease the risk of microbes in drinking water. Through the use of disinfection methods in drinking water, there is a likelihood of diminished risk of microbes within the drinking water throughout communities. Exposing consumable water to hazardous chemicals does not come without complications; there is an inherent risk in the formation of disinfection by-products (Serrano et al., 2011). These disinfection by-products are the result of disinfection chemicals coming into contact and reacting with natural organic matter (Bougeard et al., 2010). With the amounts of hazardous chemicals being in such minute quantities, a reliable detection method is required. This can be achieved through the use of chromatography and mass spectrometry. Through these methods of detection chemical compounds can be isolated and identified while giving accurate

    Based on the readings and your own research, answer the following questions: 1. How do pathogenic organisms get into a water source? Human and animal wastes (feces) are major source for pathogenic organisms (such as bacteria, viruses, and protozoa) into a water source (surface or groundwater). As water (surface runoff) resulting from the storm or precipitation or snowmelt runs over the land surface, it will pick up potential pollutants include pathogenic organisms as it runs over livestock excrement from barnyards, pastures, rangelands, feedlots. Furthermore, the discharge from the areas of land application of sewage sludge deposit or effluents discharge from wastewater into freshwater and the seepage of the human waste from a septic tanks.…

    . It was also revealed by NSW (2000) that there are a few variations in the sources of gray water in that bathroom (hand basin, shower, and bath) which generates about 38% of the household wastewater flow (55% of greywater) and is considered to be the least contaminated type of greywater. Microbiologically, thermotolerant coliform concentrations have been assessed in shower and bath water to be in the range of 104 to 106 cfu/100mL. People often urinate in showers and baths concern is often expressed about the increased health aspects of inappropriate disposal. While urine in a healthy person is sterile, some bladder infections may pass microorganisms in urine.…

    Bleach was found to be a successful disinfectant against the bacterium S.epidermidis and E.coli, at all concentrations. Bleach is a household chemical substance that acts as a halogen-releasing agent specifically releasing chlorine. As bleach is an oxidizing agent, it facilitates the surge of cellular activity of Hsp33, which are redox-regulated chaperone proteins of the bacterial cell. This chaperone protein prevents the bleach from oxidizing the bacteria, which protects the cell against protein unfolding. Due to it being a stress protein, at especially high concentrations of bleach, these redox reactions lead to an over-activation of the protein, ultimately causing overstress and death.…

    Bacteriophages (phages) are viruses that exclusively infect and replicate within bacterial cells. Phages are ubiquitous, with an estimated 1x106 particles per drop of seawater and as many as 1x108 particles per g of soil. Phage predation destroys an estimated one-half of the bacterial population worldwide every 48 h, hence regulating the population dynamics of natural bacteria (Deresinski 2008). Bacteriophages attach to their host cell by specialized structures called tail fibers, inject their nucleic acid into the bacterium and hijack the host cell machinery.…

    Discussion The cleanliness of tap water is determined by comparing many different factors of the water’s composition to the acceptable or ideal levels that have been set for “healthy” water. The water samples from each city show that the tap water remains within an acceptable range. For instance, the acceptable level for Nitrate in water is 10 ppm, a maximum level enforced by the Environmental Protection Agency, and each city did not exceed that amount with the highest level being 5 ppm in one sample of Royal Palm Beach and one sample of Palm Beach Gardens (“Basic Information about Nitrate”, n.d.). Nitrite, which usually occurs in water due to runoff from fertilizers or leaching from septic tanks and sewage, is also limited to 1 ppm, which none of the samples exceed 0.5 ppm individually, or 0.2 ppm on average (“Basic Information about Nitrite”, n.d.).…
