How was the water filtered to remove debris and living organisms?

2 answers:

The most common method in removing debris and living organisms is through a series of sedimentation and heat application. The role of sedimentation is to use gravity in separating drinkable water and visible debris. While treating water with heat kills the living organisms.

Step-1: Coagulation

Coagulation removes fine particles suspended in water, after removing rough debris by filtering through the screen.
Alum and other chemicals are added to water to form small sticky particles called floc, which attracts suspended particles.
The combined weight of these particles and alum (floc) becomes heavy enough to sink.

Step-2: Sedimentation

Coagulated particles fall gravitationally through the water in a settling tank and accumulate at the bottom of the tank, cleaning water from much solid debris.

Step-3: Filtration

To remove solid particles that were previously unremoved by sedimentation, water from the sedimentation tank flows through:

sand,
gravel,
coal, and
activated charcoal.

Step-4: Disinfection

Disinfection methods are applied to filtered water to destroy hazardous microorganisms as living organisms.

A chlorine residue is added to water when leaving the processing plant to help protect treated water from recontamination when moving through the distribution system.

<h3>Further explanation</h3>

Chemical precipitation or coagulation with various aluminum salts (e.g., alum), iron, lime, and other organic or inorganic chemicals is widely used to treat water to remove colloidal particles (turbidness) and microbes.

Water treatment with the addition of coagulants and chemical deposits has been carried out since ancient times.

There are main things to know about the different terms of water purification and filtration because they are not synonyms.

Water filtration is a treatment for eliminating debris, and some bacteria as living organisms, through several types of filters like cloth or nets.
Water purification is a chemical or UV process (with heat treatment) to deactivate bacteria and other hazardous substances that are not functioning.

what is a hypothesis reffered to as after being verified by a large number or independent experiments

Iteru [2.4K]

Answer:

The hypothesis may or may not be true and needs to be tested. It might be the answer to the problem. Hence, it must be tested thoroughly. When these predictions are tested again and again in independent scientific experiments and gets verified, the hypothesis is converted into a scientific theory.

What TWO things happen to solar radiation that reaches earth?

-Dominant- [34]

The energy of the reflected radiation goes back into outer space. The other 70% of solar radiation that gets to Earth is absorbed. Most of the energy is absorbed by oceans, landforms, and living things.

Calculate the equivalent resistance for both circuits. Series circuit: 2 Ω and 4 Ω Parallel circuit: 2 Ω and 4 Ω Which circuit h

goldenfox [79]

Equivalent resistance is also known as the overall resistance.

For resistors in a series circuit, the total resistance is computed using the formula:

$R_{T} = R_{1}+ R_{2}+ R_{3}... R_{n}$

In other words, you just add up the resistance of each resistor in the series circuit. In your case you only have two resistors. You have 2Ω and 4Ω. So all you need to do is add that up.

$R_{T} = R_{1}+ R_{2}$
$R_{T} = 2 + 4=6$

The total resistance of the series circuit is 6Ω

In a parallel circuit you get the total resistance using the formula:
$\frac{1}{R_{T}} = \frac{1}{R_{1}}+\frac{1}{R_{2}}+\frac{1}{R_{3}}...+\frac{1}{R_{n}}$

First you get the sum of all fractions and at the end take the reciprocal of the resulting fraction and divide. So let us take your problem into consideration where you have two resistors that have a resistance of 2Ω and 4Ω.

$\frac{1}{R_{T}} = \frac{1}{R_{1}}+\frac{1}{R_{2}}$
$\frac{1}{R_{T}} = \frac{1}{2}+\frac{1}{4}$
$\frac{1}{R_{T}} = \frac{2}{4}+\frac{1}{4}$
$\frac{1}{R_{T}} = \frac{3}{4}$

Get the reciprocal of the resulting fraction 3/4 and then divide. The reciprocal of 3/4 is 4/3.

4/3 = 1. 33Ω

So if you compare the equivalent resistance of the two circuits, the series circuit has a higher equivalent resistance.
