How to use bacteria as a treatment for sewage waste

Biology
2 answers:
Andrei [34K]2 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.

Water can move freely through the membrane from a higher to a lower concentration in a transportation process called _____.
nignag [31]

Answer: The correct answer for the fill in the blank is osmosis.

Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute is lower to a region where the concentration of solute is higher though a semipermeable membrane.

In other words, it is the water movement from an area where its ( water ) concentration is higher to an area where its concentration is lower.

This process does not require any energy as water is moving along the concentration gradient.

Should existing structures build from CCA-treated wood be removed?
stiks02 [169]
<span>Chromated copper arsenate, or CCA, is a pesticide that has been used for years in pressure-treating lumber to prevent destruction from rot and insects. Arsenic, a toxic chemical, can leach from this treated wood, leaving residues on the wood’s surface and in nearby soil. Young children who play on or near decks or playscapes made from CCA- treated wood can get arsenic on their skin and into their bodies, especially if they eat or drink without washing their hands. Because of the health risks of long-term exposure to arsenic, the Environmental Protection Agency (EPA) has announced that as of December 31, 2003, arsenic Currently the EPA does not recommend that people remove existing structures made with CCA-treated wood or the soil surrounding those structures. However, they do recommend that people reduce their potential exposure to arsenic.</span>
