THE REFINER

1. The problem that we are committed to solve is one of the crucial problem all over the country and it is water pollution.

Note one thing: We say that there are different rivers currently polluted in Bangladesh and there exists pollutants of different attributes. However we chose Buriganga river for refining. The way we solve this we guess that the other rivers can also be solved in that way. So all the statistical data presented here is all about Buriganga river.The solution we propose will also be applicable for Buriganga river. So our major concern will be Buriganga river.

2.We propose a solution using magnetism separating harmful particles from water and that we are going to do by the attribute called para magnetism of a substance.

3.Our solution will change the life of people in our country as we are suffering from the polluted water problem of in buriganga.

Our concept not only deal with the polluted water of buriganga but also an attempt to change the water condition all over the world. So we are going to show you 2 things here,

1.How largely the problem has spreaded.

2.What may be the contributing factors.

The problem of water pollution in Bangladesh needs no saying. Specially the problem of Buriganga river. As the capital of a country it is surrounded with a dirty river and people living in this city are the worst sufferers of this problem.

The contributing factors in our model is we going to make it drinkable water. By using magnetism we are going to extract the heavy metal from the water.By this we will reduce the heavy metal concentration in water.

The people who are suffering for a very long time just because of the water pollution, precisely the dirty water of Buriganga river we are going to work for them. Actually as an inhabitant I really had a very worst experience about how the polluted water affected us. That's why me along with my team are committed to do this job.

The solution makes the water completely drinkable which addresses their long awaited solution. The drinkable water they had been expecting from the government will come true by this solution.

We propose a complex mechanism of using magnetism by which we are going to solve the problem.

There are three parts regarding the solution:

• Necessary aspects

• Structure of the mechanism

• How it works.

1.Necessary aspects:

1.Strong magnetic field with a strong  power(0.15 Tesla) so that it can extract the metals like Cr,Cu,Ni etc.

2. All the necessary things needed to create that magnetic field.

3. ppm meter.

2.Structure of the mechanism:

We will collect water from the Buriganga river by pipes. After that we will contain the water to a large bowl type container where exists three arrangements,

1. Strong magnetic fields as explained.

2. ppm reader to take the reading

3. Electricity supply units for creating magnetic fields.

3.How it Works:

Firstly we are going to say that for extracting metals from water we will use the attribute of para magnetism of the atom. 

From a research data we find the heavy metals concentration given below vitally present  in water  for that reason the water becomes undrinkable.

1.Cr:7.7656 mg/l

2.Cd:0.0198 mg/l

3.Ni:0.2070 in mg/l 

4.Cu:0.0304 in mg/l 

5.Zn: 0.3021 in mg/l 

(Study of hydro-chemistry and pollution status of the Buriganga river, Bangladesh-M. Sarkar1*, A. K. M. L. Rahman1, J. B. Islam1, K. S. Ahmed1, M. N. Uddin2, N. C. Bhoumik3)

We will reduce the amount of concentration using Electromagnetism.

Firstly the electronic configuration,

Cr:[Ar] 3d5 4s1

Cd:[Kr] 4d10 5s2

Cu:[Ar] 3d10 4s1

Zn:[Ar] 3d10 4s2

Ni:[Ar] 3d8 4s2

From the above particles we get Cu,Cr as para magnetic substance. 

So they are going to be easily extracted if we use the proper magnetism over them. 

The problem is with Zn and Cd which are Diamagnetic. For them we are going to use another magnetic field on above of the bowl which will repel the diamagnetic substances. The power of that magnetic field will be less than the magnetic field we are going to use in water. but that will be enough to repel the substances in the water to push it downwards. That is how they are going to be stored under water after the proceedings ends. 

Ni is a Ferromagnetic substance which will certainly be attracted by  magnetic field as like the para magnetic substances. 

Para magnetic substances will also be stored under the water. After everything ends we find everything under water and extracted.
