Filtration

In Elmira, NY, 65,000 residents rely on the Elmira Water Board to provide a fresh source of surface water. Local filtration plant produces on a daily average 2.26 billion gallons of fresh drinking water, which approximately 6.2 million gallons are used on average each day. Approximately, six million residents of the state consume an average 110 gallons of drinking water per day, per person. New York State Dept. of Health evaluates the water quality throughout the state as well as the Elmira…

Discussion of Results During the first week the goal was to determine the unknown compound. In order to determine the unknown compound, many tests were performed testing the solubility, pH level, conductivity, cations present (flame test), and the anions present in the compound. The anion test had positive results for the sulfate test due to the formation of a white precipitate, indicating the presence of a sulfate ion. For the sulfate test the unknown solution, potassium sulfate, and combining…

Urinary system Objective: to distinguish key microscopic components of the renal cortex and the Meduna. Also identify the structural components of the nephron. Describing the structures of the surface across which, filtration occurs. Also, identifying the proximal tubule, distal tubule and connecting duct. Name and identify the ureter, bladder and urethra Introduction: The urinary system consists of two kidneys. The urinary system performs many functions removing waste, products from the…

Through the ideas of Harald Bauder, the Canadian immigration regulation is perceived as a filtration process. This filtration process is designed to scan through candidates purely based on education level, sought after skills and capital investment potential. With migrants that possess large sums of wealth having a distinct advantage and usually allowed into Canada. Bauder further suggests that having open borders would be advantageous for the lower socioeconomic classes from lesser developed…

that can reduce the risk of developing hypertension and renal failure. Nicotine in cigarettes causes vasoconstriction of the blood vessels and increased heart rate; both factors raise the individual’s blood pressure, which will in turn affect the filtration rate of the…

Discussion of Results: This experiment consists of three different parts. The main goal of the experiment is to identify the unknown compound the lab group was given. Along with this, the group is to discover the compounds many physical or chemical properties. Lastly, the group is supposed to create and preform two syntheses of the compound and see how they compare and contrast in different areas like costs effectiveness, safety, and potential yield of the compound. Through all of these…

urine which is then removed from the body during micturition. CKD is diagnosed in stages ranging from one to five. The stages are determined by the Glomerular Filtration Rate [GFR]. The GFR is the rate at which the kidney can relieve the body of toxins or excess fluids and is determined by the quantity of nephrons [the functional filtration units of the kidney]. The GFR is decreased the further progressed the disease becomes due to the destruction of the nephrons (Porth & Porth,…

under sun, dipping of heated iron into water, filtration through gravel and sand were found in Sanskrit writings and inscriptions in ancient Egyptian tombs. As the technology and science improved, scientists also found much more complex and insured ways. 1827, Roberts Thom invented slow sand filtration. It was used worldwide but had defects. The method needed a lot of sand, and was too slow to keep up with the population increase. 1880s, rapid sand filtration was found. This method used two main…

In my time at Exell Companies I have served as the voice of our company to our clients, as I am their primary contact with our company. In a small market like Mississippi, the majority of our new business is coming from our current clients through new services and referrals. This makes customer retention and satisfaction essential to our success and I believe my experience in sales has allowed me to be more effective in maintaining and improving our client relations. While engaged with a…

substance by measuring a change in mass. To determine the concentration of the sulfate, the precipitation of Barium sulfate is done first by adding the sulfate solution with hydrochloric acid, then heating while stirring it. Next is the washing and filtration of the Barium Sulfate precipitate, using a vacuum pump and a crucible. Lastly, is the drying and weighing of the precipitate by heating the crucible in the oven and cooling it in a desiccator. The average weight of the precipitate is…
