How to use bacteria as a treatment for sewage waste

Biology
2 answers:
Andrei [34K]3 years ago
7 0

Explanation:

Biological wastewater treatment is the most common method of sanitation in the world. This technology uses different types of bacteria and other micro-organisms for the treatment and cleaning of polluted water.

Wastewater treatment is as essential to human health as it is to environmental protection. Indeed, the use of these bacteria accelerates the treatment of pollution on a small surface: the purification plant. It’s better than letting the river handle it, because even though it’s the same purification process that occurs in nature, the quantities of pollution discharged today are too high to keep the natural cycle intact.

Thus, sewage treatment plants can prevent eutrophication of rivers, for example, but also prevent the diffusion of diseases.

Municipal and industrial effluent is the main source of wastewater. And thanks to the use of micro-organisms, we are able to degrade the content of these organic wastes as they are used as a source of food and energy to grow and multiply.

Answer: hope this helps

Explanation:

Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.

aev [14]

Answer:

Nuclear fusion

Explanation:

Nuclear fusion is a process whereby the nuclei of two smaller atoms combine to form a much larger atom, accompanied with the release of energy. This is opposed to nuclear fission where a larger atom splits into simpler and smaller atoms.

According to this question, the process of releasing energy when two stoms combine to form a larger atom is called NUCLEAR FUSION. A very common example of nuclear fusion is the combination of hydrogen atoms in the sun to produce Helium atom, with the release of heat energy.

If the rate ratio (rr) and its 95% confidence interval for a cohort study is rr = 1.1 (0.7, 1.6), what is the most appropriate c
irina [24]
The correct answer is B.
There's no statically significant association between the exposure and the disease. The risk ratio does not follow the normal distribution, even it does not depend on sample size in comparison groups. The natural rr is approximately normally distributed and is used to produce confidence interval which is for the relative risk.

How would a muscle injury surrounding a broken vessel effect hemostasis?
8_murik_8 [283]
Hemostasis is the process by which bleeding is stopped, that is, a process by which the blood is kept back in the broken blood vessel. It is the first stage in the wound healing process. 
During hemostasis, three rapid steps occur simultaneously. In the first step, the blood vessel constrict in order to reduce the quantity of blood that is flowing out, secondly, platelets stick together in order to form a temporary seal which covers the break and thirdly blood clottings formed by adding fibrin threads which serves as molecular glue on the surface of the wound.
