What are the differences in color, smell, visibility, and so forth between the “contaminated” water and the “treated” water? Answer = As for the difference for this two that it’s clear it looks cloudy and it looks like regular water. And it looks clear. I believe the contaminated water look dark brown and it smelled like soil potting and it was dirty. After the potting water it moved to the top of the
The density of most oils is less than the density of water, that is the reason why it floats (Effects of Oil Spills on Wild Life and Habitat, 2004). Oil spills are by products of human activity where in oil is leaked from ships, shore facilities, pipelines and offshore platforms. The largest contributors to oil spills are automobiles, boats, industrial plants and machinery, not the tankers and ships that carry large amounts of oil (Oil spills: Severity and Consequences to Our Ecosystem, 2012). According to the U.S. Fish and Wild Life Service, oil spills affects the wildlife and their habitats in several ways.
From the sociological perspective, it was a huge social, cultural, economic and psychological threat for the communities living across the coastlines, cleanup workers, and especially children. Firstly, oil was released into the sea; it spread out on the surface of the water and contaminated the sea and coastlines. Statistics had shown that the Gulf oil spill killed 3,902 birds, 517 turtles, 71 marine mammals and more than thousands of other wildlife animals under the sea are covered by oil during or after the disaster (Merchant, 2010). Besides, the contaminated
Chapter 1 Introduction 1.1 Background Disinfection is applied in water as well as wastewater treatment as a finishing step so as to destroy pathogens but the cause of concern regarding the disinfection process is the formation of disinfection byproducts (DBPs). Natural organic matter (NOM) in water has been considered as the predominant DBP precursors. Disinfectants are powerful oxidants that oxidize the organic matter present in water forming DBPs. Chlorine, ozone, chlorine dioxide, and chloramines are the most common disinfectants used nowadays and each produces its own suite of chemical DBPs in finished drinking water (Richardson, 2003). DBPs so formed pose a threat to human health
In the US alone, the Office of Response and Restoration of the National Oceanic and Atmospheric Administration (NOAA) responds to over a hundred oil spills each year (NOAA). While spills happen on both land and water, ocean spills are much more difficult to contain and recover from. They happen easily, almost too easily, either caused by carelessness, accidents, or natural disasters, and their negative environmental impacts could take decades to recover from. It seems like as long as humans are still depending on oil, spills will continue to wreck havoc on marine life. Oil harms marine animals both physically and chemically.
Analysis: Yes, we think that we produced an environmentally safe fluid and potable drinking water as our collected distillate from the mixture is odourless and colourless. It is as clear as water when we compared it with water and it does not have any visible particles too. The moringa seeds also removed most bacteria from the mixture. Thus the liquid produce is environmentally safe. Success of Water Treatment Machine (Instruction: Base on the priorities determined with the decision matrix, evaluate the success of your machine on a scale of 1 – 10 whereby 1 is the lowest possible score and 10 is the highest possible score.
The Gulf spill was the world’s largest accidental spill. The spill had an estimated 206 million gallons spilt into the ocean. The spilt began when an oil well a mile underground the surface of the Gulf blew. It caused an explosion that killed 11 people. BP (the oil company) tried to plug where the oil was coming, but they were unsuccessful.
Deepwater Horizon Explosion and Oil Spill The incident occurred due to the uncontrolled release of pressure from the oil well and the failure of the pressure control system to contain the pressure, thus leading to an explosion. Following which, the oil rig sank on 22nd April 2010 and led to the largest oil spill in the history of petroleum industry. The risk of oil spill could have been reduced if BP had taken the appropriate measures; as reports have stated that BP were aware of the metal casing for the blowout preventer breaking down under high pressure and yet improper maintenance was done to preserve the functionality of the pressure control system. Environmental impact The oil spill posed detrimental effects on both the marine ecosystem as well as the lives of humans in the affected region. In total, approximately 4.9 million barrels of crude oil were spilled into the water, leading to the suffocation of marine life due to its toxicity.
Exploration, transportation, and exploitation of crude oil can cause marine and terrestrial oil pollution. Oil spill is harmfull for marine environment. Lead (Pb) and Cadmium (Cd) in gasoline are the examples of heavy metal that are usually contained in gasoline and it can be stick and make soil is contaminant. Thus, the industrial waste needs a
Many people are familiar with tanker accidents, since they are highly publicized, and they release large volumes of oil into the ocean. Only a small percentage of global oil spills are related to tanker accidents due to explosions, hull failure, or running aground, however. These spills tend to be very harmful because of the sheer volume of oil released at once, and they pose a serious threat to marine animals and seabirds. Such disasters frequently bring attention to issues with safe oil handling, which can lead to reforms in petroleum regulation. Oil spills in the water can also be caused by natural seepage.
