How to prevent water pollution and the treated of water pollution

| How to prevent water pollution? |
If you want to help keep our waters clean, there are many things you can do to help. You can prevent water pollution of nearby rivers and lakes as well as groundwater and drinking water by following some simple guidelines in your everyday life.
Before raw sewage can be safely released back into the environment, it needs to be treated correctly in a water treatment plant. In a water treatment plant, sewage goes through a number of chambers and chemical processes to reduce the amount and toxicity of the waste.
- Conserve water by turning off the tap when running water is not necessary. This helps prevent water shortages and reduces the amount of contaminated water that needs treatment.
- Be careful about what you throw down your sink or toilet. Don’t throw paints, oils or other forms of litter down the drain.
- Use environmentally household products, such as washing powder, household cleaning agents and toiletries.
- Take great care not to overuse pesticides and fertilisers. This will prevent runoffs of the material into nearby water sources.
- By having more plants in your garden you are preventing fertiliser, pesticides and contaminated water from running off into nearby water sources.
- Don’t throw litter into rivers, lakes or oceans. Help clean up any litter you see on beaches or in rivers and lakes, make sure it is safe to collect the litter and put it in a nearby dustbin.

| The various processes for treating polluted water |
- The sewage first goes through a primary phase. This is where some of the suspended, solid particles and inorganic material is removed by the use of filters.
- The secondary phase of the treatment involves the reduction of organic, this is done with the use of biological filters and processes that naturally degrade the organic waste material.
- The final stage of treatment is the tertiary phase; this stage must be done before the water can be reused. Almost all solid particles are removed from the water and chemical additives are supplied to get rid of any left-over impurities.
Denitrification is an ecological approach that can be used to prevent the leaching of nitrates in soil, this in turn stops any ground water from being contaminated with nutrients.
- Fertilisers contain nitrogen, and are often applied to crops by farmers to help plant growth and increase the yield.
- Bacteria in the soil convert the nitrogen in the fertilizer to nitrates, making it easier for the plants to absorb.
- Immobilization is a process where the nitrates become part of the soil organic matter.
- When oxygen levels are low, another form of bacteria then turns the nitrates into gases such as nitrogen, nitrous oxide and nitrogen dioxide.
- The conversion of these nitrates into gas is called denitrification. This prevents nitrates from leaching into the soil and contaminating groundwater.
Septic tanks treat sewage at the place where it is located, rather than transporting the waste through a treatment plant or sewage system. Septic tanks are usually used to treat sewage from an individual building.
- Untreated sewage from a property flows into the septic tank and the solids are separated from the liquid.
- Solid material is separated depending on their density. Heavier particles settle at the bottom of the tank whereas lighter particles, such as soap scum, will form a layer at the top of the tank.
- Biological processes are used to help degrade the solid materials.
- The liquid then flows out of the tank into a land drainage system and the remaining solids are filtered out.
Ozone wastewater treatment is a method that is increasing in popularity. An ozone generator is used to break down pollutants in the water source.
- The generators convert oxygen into ozone by using ultraviolet radiation or by an electric discharge field.
- Ozone is a very reactive gas that can oxidise bacteria, moulds, organic material and other pollutants found in water.
- Using ozone to treat wastewater has many benefits:
- Kills bacteria effectively.
- Oxidises substances such as iron and sulphur so that they can be filtered out of the solution.
- There are no nasty odours or residues produced from the treatment.
- Ozone converts back into oxygen quickly, and leaves no trace once it has been used.
- The disadvantages of using ozone as a treatment for wastewater are:
- The treatment requires energy in the form of electricity; this can cost money and cannot work when the power is lost.
- The treatment cannot remove dissolved minerals and salts.
- Ozone treatment can sometimes produce by-products such as bromate that can harm human health if they are not controlled.
Ecosystem
An ecosystem is a complex set of relationships among the living resources, habitats and residents of an area.
It includes plants, trees, animals, fish, birds, microorganism, water, soil, and people.
Ecosystem vary greatly in size and the elements that make them up, but each is a functioning unit of nature.
Everything that live in ecosystem is dependent on the other species, and elements that are also part that ecological community. If one part of an ecosystem is damages or disappear, it has an impact on everything else.
When an ecosystem is healthy, scientists say it is sustainable. This means that all elements live in balance and all are capable to reproducing themselves. This is usually biodiversity, meaning that there are a variety of living organisms and species in that environment.
Since ecosystems can be as small as a single tree or as large as entire forest, there
are lots and lots of different ecosystems in the Upper Peninsula of Michigan. When
you want to talk about how a certain natural area functions together, you can call it
a biome. A biome is a very specialized ecosystem that only exists in a certain
area or climate. They are identified by factors like temperature, rainfall, soil type and
altitude.

An atheist professor of Philosophy was speaking to his class on the problem Science has with GOD. He asked one of his new Christian Students to stand and . . .
Professor : You are a Christian, aren't you, son ?
Student : Yes, sir.
Professor: So, you believe in GOD ?
Student : Absolutely, sir.
Professor : Is GOD good ?
Student : Sure.
professor: Is GOD all powerful ?
Student : Yes.
Professor: My brother died of cancer even though he prayed to GOD to heal him. Most of us would attempt to help others who are ill. But GOD didn't. How is this GOD good then? Hmm?
(Student was silent.)
Professor: You can't answer, can you ? Let's start again, young fella. Is GOD good?
Student : Yes.
Professor: Is satan good ?
Student : No.
Professor: Where does satan come from ?
Student : From . . . GOD . . .
Professor: That's right. Tell me son, is there evil in this world?
Student : Yes.
Professor: Evil is everywhere, isn't it ? And GOD did make everything. Correct?
Student : Yes.
Professor: So who created evil ?
(Student did not answer.)
Professor: Is there sickness? Immorality? Hatred? Ugliness? All these terrible things exist in the world, don't they?
Student : Yes, sir.
Professor: So, who created them ?
(Student had no answer.)
Professor: Science says you have 5 Senses you use to identify and observe the world around you. Tell me, son, have you ever seen GOD?
Student : No, sir.
Professor: Tell us if you have ever heard your GOD?
Student : No , sir.
Professor: Have you ever felt your GOD, tasted your GOD, smelt your GOD? Have you ever had any sensory perception of GOD for that matter?
Student : No, sir. I'm afraid I haven't.
Professor: Yet you still believe in Him?
Student : Yes.
Professor : According to Empirical, Testable, Demonstrable Protocol, Science says your GOD doesn't exist. What do you say to that, son?
Student : Nothing. I only have my faith.
Professor: Yes, faith. And that is the problem Science has.
Student : Professor, is there such a thing as heat?
Professor: Yes.
Student : And is there such a thing as cold?
Professor: Yes.
Student : No, sir. There isn't.
(The lecture theatre became very quiet with this turn of events.)
Student : Sir, you can have lots of heat, even more heat, superheat, mega heat, white heat, a little heat or no heat. But we don't have anything called cold. We can hit 458 degrees below zero which is no heat, but we can't go any further after that. There is no such thing as cold. Cold is only a word we use to describe the absence of heat. We cannot measure cold. Heat is energy. Cold is not the opposite of heat, sir, just the absence of it.
(There was pin-drop silence in the lecture theater.)
Student : What about darkness, Professor? Is there such a thing as darkness?
Professor: Yes. What is night if there isn't darkness?
Student : You're wrong again, sir. Darkness is the absence of something. You can have low light, normal light, bright light, flashing light. But if you have no light constantly, you have nothing and its called darkness, isn't it? In reality, darkness isn't. If it is, were you would be able to make darkness darker, wouldn't you?
Professor: So what is the point you are making, young man ?
Student : Sir, my point is your philosophical premise is flawed.
Professor: Flawed ? Can you explain how?
Student : Sir, you are working on the premise of duality. You argue there is life and then there is death, a good GOD and a bad GOD. You are viewing the concept of GOD as something finite, something we can measure. Sir, Science can't even explain a thought. It uses electricity and magnetism, but has never seen, much less fully understood either one. To view death as the opposite of life is to be ignorant of the fact that death cannot exist as a substantive thing.
Death is not the opposite of life: just the absence of it. Now tell me, Professor, do you teach your students that they evolved from a monkey?
Professor: If you are referring to the natural evolutionary process, yes, of course, I do.
Student : Have you ever observed evolution with your own eyes, sir?
(The Professor shook his head with a smile, beginning to realize where the argument was going.)
Student : Since no one has ever observed the process of evolution at work and cannot even prove that this process is an on-going endeavor. Are you not teaching your opinion, sir? Are you not a scientist but a preacher?
(The class was in uproar.)
Student : Is there anyone in the class who has ever seen the Professor's brain?
(The class broke out into laughter. )
Student : Is there anyone here who has ever heard the Professor's brain, felt it, touched or smelt it? No one appears to have done so. So, according to the established Rules of Empirical, Stable, Demonstrable Protocol, Science says that you have no brain, sir. With all due respect, sir, how do we then trust your lectures, sir?
(The room was silent. The Professor stared at the student, his face unfathomable.)
Professor: I guess you'll have to take them on faith, son.
Student : That is it sir . . . Exactly ! The link between man & GOD is FAITH. That is all that keeps things alive and moving.
P.S.
I believe you have enjoyed the conversation. And if so, you'll probably want your friends / colleagues to enjoy the same, won't you?
Forward this to increase their knowledge . . . or FAITH.
By the way, that student was Einstein.!
