Literature Review Introduction Coagulation and flocculation processes are essential in a number of diverse disciplines including biochemistry, rubber manufacturing and in water and wastewater treatment (Bratby, 2006). These processes are typically used in destabilizing, agglomerating and subsequent removal of particles. Coagulation is a physico-chemical process which neutralizes the colloidal particles in water by a chemical called coagulant. The neutralization forces the colloidal particles to join

When asked to think of coal mining, what comes to mind? A mountain with a hole cut into the side of it with a set of railroad tracks disappearing into it? Maybe an old mine car or two full of some rocks or coal, with a pickaxe and shovel leaning against it. A few guys with hard hats covered in a black powder coming walking out of the mine pushing a car or two full of coal. The technology has advanced but the process is basically still the same as well as the outcome. Coal is retrieved from underground

not even begun to scratch the surface of grasping a full understanding of it. The sea is the largest biological habitat on this earth and is not understood. There are so many undiscovered incredible organisms are all potential he homes by deep-sea mine. Extreme temperatures, pitch black darkness and a giant amount of bio diverse city, most of which are very sensitive to any disturbance just a little light could throw them off. Is sure of all this, with such a limited understanding of all these concepts

The disease environment of a particular area can be shaped by a number of things, some of which are economic, social, and political shifts in the area. During the 19th century as urbanization and industrialization grew economic, social, and political changes occurred. While these major shifts changed the dynamics of cities they also changed the dynamics of disease. Industrialization and urbanization created a social shift that caused a new working class to emerge which brought on new health problems

carcinogenic. Companies divulge little regarding the precise composition of the chemicals used, but it is known that there are approximately 700 known different chemicals used for this process. Although the fluid used in fracking is mostly water, some acids, emulsifiers and other chemicals are added to make the water more viscous and effective at fracturing the rock. These include guar gum, boron, zirconium, titanium, iron and polyacrylamide.Aside from such additives, the process of fracking also releases

pollution. These forms of pollution can be further broken down into non-point and point source pollutions, hazardous waste disposal, acid rain, eutrophication, marine pollution, thermal pollution, heavy metal poisoning, Thermal pollution, Urban runoff & flooding, Heavy metal poisoning, Wastewater, Fish kill, Algal blooms, Mercury in fish, Smog, Tropospheric ozone, Acid mine drainage, Mountaintop removal mining and many more. We will focus on the three main forms of pollutions. Water pollution occurs when

1. Introduction Open Educational Resource are teaching, learning and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use or re-purposing by others (William & Foundation, 2015). According to Hurt (2013) they include full courses, course materials, modules, textbooks, streaming videos, tests, software and any other tools, materials or techniques used to support access to knowledge. Water is essential to sustain

1 What is your main research question and hypothesis? Question= Have there been any declines in the riverine ecosystem of the Nisqually river and if so what are the declines caused by? Hypothesis: Due to the recent study published in the peer-reviewed journal Global Change Biology says increased flow variability has crucial negative effects on salmon populations of multiple climate factors considered and the salmon quality over the recent years showing a decline the prediction is the findings will

The 16S rRNA gene sequences amplified from cranberry bogs resolved into 49 bacterial phyla. The overall bacterial composition of the different samples was similar, particularly among the six most highly-represented groups (Fig. 1). Proteobacteria, Acidobacteria, Bacteroidetes, and Verrucomicrobia were the most dominant phyla (relative abundance > 5 %) in every sample, together accounting for about 78 % of the bacterial sequences in the soils examined. The Actinobacteria and Chloroflexi were also

What comes to your mind when you think of pollution? Is it air pollution? Is it water pollution? Both of these are crucial to understand and should pop into your head when think of pollution. According to Merriam-Webster, pollution is “the action of polluting especially by environmental contamination with man-made waste; also: the condition of being polluted.” I would like the audience to use this definition to further their understanding of what pollution is. This could be anything from an inconsiderate
