Dynamic – The removal of phosphorus from wastewater incorporates the joining of phosphate into TSS and the subsequent departure of those solids. Phosphorus can be joined into either natural solids (e.g., microorganisms) or invention hurries. Tertiary filtration upheld by compound development can decrease signify phosphorus obsessions in the last spouting to low levels. To finish low phosphorus obsessions, chemicals must be added to wastewater to accomplice phosphorus with solids that can then be viably removed through filtration. Aluminum-or iron-based coagulants and polymer are the chemicals most for the most part used consequently.

Presentation – Phosphorus and nitrogen are supplements that are vital for maritime plant and green development advancement. Most waters regularly contain enough of these supplements to support neighborhood maritime life. In any case, an abundance of these supplements can over-sustain plant and green development advancement such that they make water quality issues. Common sewage contains phosphorus on a very basic level from human stool and mechanical waste. Phosphorus is a particularly risky constituent since it serves as a basic supplement for green development improvement. Right when the phosphorus availability deals with the advancement solicitations of green development, over the top green development blooms can happen. Exactly when the green development go on, they are consumed in an oxygen asking for procedure, as minuscule life forms degenerate them as normal matter. This oxygen hobby can debilitate the separated oxygen supply in the tolerant body, which can execute off fish species and surprise the maritime environment. Typical untreated private wastewater can contain 5-20 mg/L of total phosphorus (Davis and Masten, 2014). The arrivals of treated wastewater can be the most foremost wellspring of phosphorus stacking in the…...

...Civil Engineering has been an aspect of life since the beginnings of human existence. The earliest practices of Civil engineering may have commenced between 4000 and 2000 BC in Ancient Egypt and Mesopotamia (Ancient Iraq) when humans started to abandon a nomadic existence, thus causing a need for the construction of shelter. During this time, transportation became increasingly important leading to the development of the wheel and sailing. Until modern times there was no clear distinction between civil engineering and architecture, and the term engineer and architect were mainly geographical variations referring to the same person, often used interchangeably. The construction of Pyramids in Egypt (circa 2700-2500 BC) might be considered the first instances of large structure constructions. In the 18th century, the term civil engineering was coined to incorporate all things civilian as opposed to military engineering. The first engineering school, The National School of Bridges and Highways, France, was opened in 1747. The first self-proclaimed civil engineer was John Smeaton who constructed the Eddystone Lighthouse. In 1771, Smeaton and some of his colleagues formed the Smeatonian Society of Civil Engineers, a group of leaders of the profession who met informally over dinner. Though there was evidence of some technical meetings, it was little more than a social society. In 1818, world’s first engineering society, the Institution of Civil Engineers was founded in London, and......

...Construction Engineering This civil engineering branch deals with the planning, construction and maintenance of structures. Construction engineering is the planning and execution of designs from site development, environmental, structural, transportation and structural engineers. They must ensure that the plans that have been designed by other engineers are implemented to their exact specifications. Construction engineers will supervise field work during the entire project. They are in a sense a cross between an engineer and manager as they will oversee the project from start to finish and handle any problems that come up throughout the duration of the project. Structural Engineering This branch of civil engineering encompasses the structural analysis and design of structures. It is the responsibility of the structural engineer to analyze and design a structure that will safely bear or resist the stresses, forces and loads. The design must satisfy the project specifications while meeting all safety regulations. The structure must endure massive loads as well as natural disasters and climate changes. Geotechnical Engineering In geotechnical engineering the engineer studies soil, foundations and bearing capacities. The engineer will study the behavior of the earth materials and how they will affect a structure that is to be constructed. They will also evaluate pre-existing structures that are showing signs of problems with the earth materials under or near the......

...abrasives belong to the fine ceramics category. The category of coarse ceramics includes, for example, brick or conventional refractory materials. It also refers to  refers to ceramic products for engineering applications. High-performance ceramic is defined in DIN V ENV 12 212 as a "highly-developed, high-strength ceramic material, which is primarily non-metallic and inorganic and possesses specific functional attributes." The concept high-performance ceramics is primarily used to distinguish them from traditional ceramics based on clay, including tableware, sanitary ware, walls and floor tiles as well as ceramics for civil engineering. This definition agrees with that of the "Japanese Fine Ceramics Association". Structural or construction ceramics are terms that have not yet been standardised, referring to materials that in some way must withstand mechanical stresses, bending or pressure for example. Functional ceramics are high-performance ceramics in which the inherent characteristics of the material play an active role, for example ceramic parts which possess specific electric, magnetic, dielectric or optical properties. Electrical ceramics are high-performance ceramics that are applied because of their specific electric or electronic characteristics. Electrical engineering applications make use primarily of the excellent insulating characteristics and mechanical strength. The electronics industry also takes advantage of characteristics such as ferroelectric......

... but he is later tormented by physically and mentally wounds, which he got from the war, from which he suffers. Ron is developing throughout the film and you could easily say that the first phase is before the war, the second is during the war and the third is after the war. The film is not only trying to tell the viewer the personal development of Ron Kovic but also the director, Oliver Stone, wanted to show what is was like to be a part of the Vietnam War, seen from a war veteran´s point of view. Ron Kovic is born of the 4th of July - the day The Declaration of Independence was signed in 1776, which to the Americans is a symbol of freedom and nationalism. The film is opening with a scene that shows Ron Kovic, whom is celebrating his 13th birthday and New York celebrating Independence Day with a parade of World War 2 veteran. His family is very caught up by the patriotic theme of the day, and they are very proud to have a son who is born on the 4th of July. The film takes place in the 60´s where the young boys are told that they shall be willing to fight for their country, because it shows their manhood, patriotism and national love. Furthermore they should do it in honour of their granddads that fought in the World War 2. You could say that their generation of boys have been indoctrinated at a young age where they are unable to determine what really to believe. Kovic is born and raised in Massapequa in a very religious family. He is a very talented boy, who always......

4th Admendment

...4TH AMENDMENT TECHNOLOGY ISSUES in the 21st Century The Fourth Amendment says, “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” There are a couple of areas that of a great concern to me concerning how the Fourth Amendment is written. The first is the use of cell phones by police under the “Search Incident Arrest” (SITA) doctrine. The second is the seizure of Computer Hard Drives for criminal Investigations. In Chimel v California (1969), the court ruled that if police arrest someone, they may search the body of the person without a warrant and “the area into which he might reach” in order to protect material evidence and the officers’ safety. The origin of the SITA doctrine states that police may search a suspect, and the area immediately surrounding the person, without a warrant during a lawful arrest. The case of Riley v California (2014) in which David Leon Riley was arrested on August 22, 2009, after a traffic stop and discovered loaded firearms in his car. The officer took Riley’s phone and searched through his phone and searched through his messages, contacts, videos and photographs. They charged him with an unrelated shooting that occurred several weeks prior to his arrest and was......

...ENB100 - ENGINEERING & SUSTAINABILITY Progress Report (due in Wk12 Tutorial) ! Student Name: ! Student # Your task: Your role as a professional engineer will require you to assess multiple solutions for a single problem. Often, the suitability of the solution has little to do with the price or the provider but more to do with ‘fitness for purpose’. As such, it is vital that a structured process is used to identify the most appropriate solution. This process is called an evaluation matrix. ! Your task is two-fold. Firstly, in your own words, you need to define the term ‘evaluation matrix’. Make sure your definition relates to the engineering context and provide robust references. Secondly, you need to develop suitable criteria for use in your final project. Ensure you use clear and measurable criteria that take into account the client needs. ! ! ! 1. Definition An Evaluation matrices are used in the engineering profession as a tool to evaluate a number of different types of options against a prioritised criteria. If the design ideas do not meet the criteria then two different levels of the evaluation matrices can be used. The first level effectively acts as a filter with each different option evaluating it against the mandatory criteria. (UCLA, 1-2, 2014) para The design options that meed these mandatory criteria then go on to the second level with involves them being evaluated against prioritised criteria. This is vital this......

...Introduction: This is a preliminary wastewater treatment plant design for Modeltown City with average daily flow rate of 0.500m3/s. For redundancy, the plant is designed with two trains capable of handling the full plant load individually. Bar Rack: The bar rack system should consist of at least two bar racks each capable of handling the plant full peak flow. It should be a self-cleaning system to maximize efficiency and reliability. Grit Chamber: The grit chamber is necessary for the removal of the larger suspended inorganic solids. A vortex grit chamber is recommended for constant energy efficiency over a wide range of flows, small footprint and minimal headloss. Flow Measurement: A parshall flume should be installed after the grit chamber for proper flow measurement of plant influent. For more accuracy a magnetic flow meter can be placed after the parshall flume. Equalization Basin: The wastewater treatment plant being designed requires an equalization basin to even out flow and BOD variations. The average daily flow is 0.500 m3 /s. The following flows and BOD5 have been found to be typical of the average variation over a day. This design includes an aeration system in the equalization basin which can reduce the influent BOD by 10-20%. The volume of the basin will be 9545m3. The mass of BOD5 leaving the tank will be 388kg. Un-equalized BOD Mass Loading Ratios: • Peak to Average 1.97:1 • Minimum to Average 0.140:1 • Peak to Minimum......

...Task 1 Why does engineering equipment fail, what happens when it does and what can we do about it? Equipment’s fails because certain parts of it fail first and that prevents the whole process from working. It is important to understand the problem before any maintenance. There are a lot of reasons it could fail because of the age of the equipment and parts need to be changed or if the equipment vibrates nuts and bolts can be loosen and parts can fall apart. When this happens the machine needs to be stopped and maintained. Age is very important if the machine has been used for a very long time the efficiency and the quality wouldn’t be as good as a new one, a machine has a certain life span for example on a car the timing belt must be replaced after every 50,000 miles. Wear could lead to a fault in a machine because parts come into contact with each other for example a cars break pad. Corrosion in certain materials takes longer than others like aluminium, when a part of a machine corrodes it degrade and can cause failures. Raw materials such as oil and compressed air can run equipment’s. If something different unwanted to the equipment is in it, it can affect the way the machine works. For example water in a petrol tank will cause a car to break down and this is a fouling. Lack of maintenance can cause a fail, routine maintenance such as cleaning and lubrication. This cause for example in a factory that is manufacturing can will stop the line and check the cars in that line......

Environmental Engineering

...Major: Environmental Engineering We humans have a long history of polluting our air, water, and soil. This contamination not only hurts nature, but is dangerous to people. Luckily, environmental engineers are on the job. They use math and science to clean up the messes we've made and prevent new ones from happening. For example, they might figure out how to clean up toxic material that has seeped into the ground at an old gas station or design an effective way to treat wastewater.  If you choose this major, you’ll study a wide range of subjects. Besides learning the basics of engineering, you’ll also take courses in the life and social sciences so you can understand environmental problems in all their complexity. Students in environmental engineering learn to design, develop, and evaluate structures, equipment, and systems that protect the environment from the effects of human activity and that improve public health and well-being. “[Engineering] allows you to think and be creative … We get to solve problems and [tackle] projects that seem impossible at first, but when they are completed, it's so cool. ” Cindy, junior, civil and environmental engineering, UC Berkeley It Helps to Be...Passionate about the environment. You should enjoy science and math, like solving problems, and have an eye for detail.
