IntrThe United States is among the nations that well understand the need for having a clean environment. As early as in 1995, the country designed an initiative to verify the performance of environmental technologies. For the initiative to succeed, stakeholders created a supervisory body called the Environmental Protection Agency (EPA) (Ashley et al., 2005). Since then, the ETV program has effectively initiated testing protocols and executed technological performance and verification process to improve human health and environmental protection mechanisms.
Monitoring Mercury and Ammonia
Investigating mercury and ammonia components is one of the ETV’s programs with a directive of maintaining and protecting the health of both living organisms and the country’s environment. In an educating article about the environment, Ashley et al. (2005) uncover the ways of protecting the environment from damaging substances. The report assesses the need to form a tribunal accountable for limiting air contamination caused by mercury substances. Like the air, the authors mention landfills, and surface impoundments as risk factors threatening the environment through pollution (Ashley et al., 2005). These authors equally admit to the possibilities of devising specific measures that can control mercury pollution. As stipulated in the article, the first measure is estimating the mercury level that can be harmful to human health (Ashley et al., 2005). Determining the right level of mercury that can be harmful to human health is crucial as this helps in developing proper monitoring and measuring techniques to support actions such as cleaning up mercury-affected regions.
The article as well reveals some measures and mechanisms suitable for ammonia management. Through uncontrolled industrial activities, ammonia is introduced into the atmosphere. The Environmental Protection Agency reveals that cyclonic spraying and venturing in control of environmental pollution by ammonia is one of the measures that help manage ammonia pollution. In addition, the authors suggest secondary wet scrubbers as potential inhibitors of fluoride. As much as various substances can contain ammonia from harming the environment, Ashley et al. (2015) recommend the use of phosphoric acid as an adequate substance to manage ammonia components.
Using an Equation to Compute Water Flow Rate from a Pipe Diameter
The fluid flow theory shows that fluid at static exerts pressure on the surroundings. Liquefied molecules possess unique characteristics that make the particles attract each other (Martin-Candilejo et al., 2020). The attraction is essential because the molecules remain strong to keep fluid rigidity intact. Fluids such as oil, water, and air have unique behavior that makes shear stress between layers in a directly proportional strain. Regardless of the make-up characteristics, all fluids obey the Newtonian fluid theory. Thus far, the equation defining the rate of water flow is as follows. Deriving the equation occurs by dividing the pie by the product of flow rate and velocity in pipe diameter. The speed and flow rate are the main variables in the equation: The fluid flow rate = Q = pie /4. (d) ^ 2. v Q represents the rate of water flow, and d is the pipe diameter. V is the velocity of water flowing in the pipe. Thus, determining the actual rate of water flow in the equation is more straightforward.
The Explanation of Water Treatment Methods
Scientifically, due to the main components of water, such as an oxygen and hydrogen molecule, water is assumed to be clean. However, water shares the globe’s limited space with other substances such as minerals, organic matter, and human-made pollutants. Sharing process is one of the risk factors that contaminate water (Zouboulis & Katsoyiannis, 2019). Once water is contaminated, it becomes unsuitable for drinking, hence attracting the need for water treatment mechanisms. The first treatment method is pH correction, a process that adjusts or corrects water pH levels. Fixing water pH level is done by introducing lime into a treatment procedure (Zouboulis & Katsoyiannis, 2019). Fluoridation is another crucial stage that treats community water supply terminals. According to the 1957 Act, water fluoridation is compulsory for all the water hunters (Zouboulis & Katsoyiannis, 2019). The Act stipulates that one of the best ways to ensure clean water supply is by employing fluoridation method and thus the stage is mandatory.
The Features of Solid Waste Landfill
Landfills are among the various deposits that make up an environment. These dumpsites of waste deposits occur within a milieu and are threat to the environment (Zouboulis & Katsoyiannis, 2019). The primary makeup of these sentiments occurs from the accumulation of inorganic amalgams, organic compounds, and suspended particles (Zouboulis & Katsoyiannis, 2019). The materials are then buried naturally by the environmental action. The concealed wastes gradually become wet from the action of water, hence decomposing to produce harmful substances that pollute the environment.
Hazardous Waste Onsite Remediation Technologies
Technology is as imperative to the environment as it is to supporting humanity. It offers information that takes care of eliminating water contaminants, thus preventing ecological hazards. Remediation proficiency testing is one of the currently available tools useful in managing environmental pollution. Companies in the U.S are adapting new standardization of aptitude responsible for testing performance and detecting new products’ effects on the environment (Zouboulis & Katsoyiannis, 2019). Another innovation is the Advanced Monitoring Systems (AMS), accountable for verification process. The equipment monitors and then detects water contaminants that occur intentionally to contaminate public water.
Electrostatic Precipitators Are Environmentally Helpful
The environmental gases have various dust and smoke particles that might contaminate the air. Gases that have smoky and other impurities need to undergo a filtration process for cleaning purposes. The contraption useful for the percolation process is referred to as electrostatic precipitator (Ashley et al., 2005). Apart from dust, the pragmatic invention removes carbon soot from the exhaust fumes, hence preventing the gasses from threatening the environment. The equation that determines the efficacy of the device is E=ρj.
The Computation of SPL in dB
dB represents an amplitude of sound, as measured under pressure. The sound is measured in a decibel (dB) scale. Decibel scale occurs in log, and thus useful to ensuring appropriate development of quantified sound. The calculation is as follows:
SPL(dB) = 10log10/20upa
One bulldozer is capable of producing 90 dBA. This is the same as 9.0 BA.
For two bulldozers;
S = 10(9.0) + 10 (9.0).
Two bulldozers will be: 2 x 109
log (2 x 109). = 9.30 BA. Therefore, 9.3 x 10 dBA, to make 93dBA as the results.
The Favorite Part of This Course
The course is unanimously interesting, considering that it attends to the environmental study cogently. Most enticing part is that this course connects the environment to the real world devices that utilize technology to guarantee a healthy milieu. Accordingly, this course’s technical section is fascinating as it supplements a learner with hi-tech consent. The enablement is a perfect exposure to leaners in terms of giving them the best in environmental facets.
It is vital to note that the Environmental Protection Agency (EPA) has been instrumental in ensuring the American environment is safe and suitable for human. Ammonia and mercury are the two main substances that the agency is dedicated to managing, as they are among the corporate environmental threats to human life. Environmental Protection Agency has made commendable efforts in managing the safety of water through water treatment processes.
