Biological treatment of wastewater

 

1. In the biological treatment of wastewater, microorganisms break down the organic matter, such as food, oil, and human waste, in the wastewater and forms CO2 and microbial biomass. When firefighters combat a fire near a wastewater treatment plant where agricultural pesticides are involved, explain why the wastewater treatment operators are notified. Also, explain why there are fewer inorganic pesticides that are encountered today.
2. Ammonia is a colorless gas that is easily recognized because of its pungent odor. Ammonia is often encountered as anhydrous ammonia. Describe anhydrous ammonia and at least three of its commercial uses. When there is a release, explain why emergency responders should not apply water directly to the release of aqueous ammonia. Provide its chemical reaction with water.

Sample Solution

Biological treatment of wastewater

Anhydrous ammonia is a chemical compound with the formula NH3. It is referred to as “anhydrous” because the compound does not contain water. Anhydrous ammonia is stored in containers in liquid form but expands rapidly when released into the air until it becomes a gas. It has a number of occupational uses, including laboratory uses, use as a refrigerant, and widespread use as an agricultural fertilizer. Ammonia in Water, commonly known as Aqua Ammonia, Aqueous Ammonia, renders it safe to handle and helps avoid the hazards that accompany use of Ammonia Gas by greatly reducing its vapor pressure.

talks about one of the worthwhile motivations of war, above all, is when mischief is caused however he causes notice the damage doesn’t prompt conflict, it relies upon the degree or proportionality, one more condition to jus promotion bellum (Begby et al (2006b), Page 314). Frowe, in any case, contends the possibility of “worthy motivation” in light of “Sway” which alludes to the assurance of political and regional freedoms, alongside common liberties. In contemporary view, this view is more confounded to reply, given the ascent of globalization. Likewise, it is hard to quantify proportionality, especially in war, on the grounds that not just that there is an epistemic issue in ascertaining, however again the present world has created (Frowe (2011), Page 54-6). Moreover, Vittola contends war is essential, not just for guarded purposes, ‘since it is legal to oppose force with force,’ yet in addition to battle against the out of line, a hostile conflict, countries which are not rebuffed for acting treacherously towards its own kin or have unfairly taken land from the home country (Begby et al (2006b), Page 310&313); to “show its foes a thing or two,” yet mostly to accomplish the point of war. This approves Aristotle’s contention: ‘there should be battle for harmony (Aristotle (1996), Page 187). Notwithstanding, Frowe contends “self-protection” has a majority of depictions, found in Chapter 1, demonstrating the way that self-preservation can’t necessarily in all cases legitimize one’s activities. Much more risky, is the situation of self-preservation in war, where two clashing perspectives are laid out: The Collectivists, an entirely different hypothesis and the Individualists, the continuation of the homegrown hypothesis of self-protection (Frowe (2011), Page 9& 29-34). All the more significantly, Frowe invalidates Vittola’s view on retribution in light of the fact that first and foremost it engages the punisher’s power, yet in addition the present world forestalls this activity between nations through legitimate bodies like the UN, since we have modernized into a moderately quiet society (Frowe (2011), Page 80-1). Above all, Frowe further disproves Vittola through his case that ‘right goal can’t be blamed so as to take up arms in light of expected wrong,’ recommending we can’t simply hurt another on the grounds that they have accomplished something low. Different elements should be thought of, for instance, Proportionality. Thirdly, Vittola contends that war ought to be kept away from (Begby et al (2006b), Page 332) and that we shoul
