2. Water is very essential in our lives. It has many uses, from drinking and cleaning ,to irrigating crops and landscapes. In one way or another, water is a part of almost everything humans make and do.

3. Nowadays, water supply has been one of the biggest problems in our country is facing. We are sure that some of you already experienced having or using dirty water coming out from our faucets or showers. And this is because a lot of our water resources are not that clean anymore. That is why; the government finds it difficult to provide clean water all over the country. If this will not be avoided, our safety will most likely be at stake because there will be no assurance that the water we are using is clean and safe. And so, it is essential to learn how to filter water on your own as the commercial water filtration systems could be very expensive and can cost up to thousands of pesos.

4. Since, all of us in our group are very environmental conscious, we chose to make something that will not just help our community but the world as a whole to have better environment. For our investigatory project, our group decided to create an Improvised Water Filter. This water filter is not just a simple one but this is something worth using. This Improvised Water Filter is a great help for us because this will give us the assurance that the water we are be using is cleaner than ever before and a money saver.

5. STATEMENT OF THE PROBLEM: Since, we are making Improvised Water Filter for our investigatory project; our main agenda is to prove that improvised water filter can be a way for us to have a clearer water. We also want to prove that there is an easy process to filter water in a less expensive and more environmental way. And also to prove that improvised water filter is very effective. The Improvised Water Filter we made answered a lot of questions and solved a lot of problems. This answered the problem of dirty water supply and difficulties of using commercialized water filter. This also solved our problem when it comes to expensive water filters since the materials used in this project are very affordable.

6. SIGNIFICANCE OF THE STUDY: Improvised Water Filter, indeed, plays an important role in society. It benefits all persons from different places especially those who are not always having clean water supply. It helps all persons to have a cleaner water to to use. It will also benefit those who are depriving themselves of spending too much in commercialized water filters, as well benefit those people who are environmental friendly. Improvised water filter will benefit them in a way that all their wants and needs will be provided, and satisfy them when it comes to what they most likely wanted to happen.

7. SCOPE AND LIMITATIONS OF THE STUDY: Our investigatory project covers the process of how improvised water filter can really make dirty water a clean one. It also covers the aspect of how can materials from nature be an effective source for us to make an efficient water filter. We made and studied about this improvised water filter for almost one month. And this really proved a lot of things and answered many questions in our minds. According to our study, improvised water filter is effective. And according to other researchers, this kind of water filter is really capable of doing its job. It is effectual; however, there is a possibility but only a minimal chance that the process of filtering the water will be difficult since, unlike, other commercialized water filter, an improvised one is only made of sand, pebbles, carbon, etc. But since, water filter is a cycle, the continuous filtration will certainly make a dirty water clean. Based on our one-month study, we can say that making this improvised water filter is not that difficult. The only limitation is that the number of cycle that the water needs to be filtered depend on the quantity and quality of the water, the darker and larger amount of the water, means more cycle.

8. Definition of Terms Activated carbon- is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. adsorbent- material which can adsorb a chemical or contaminant out of solution. aesthetic- meaning pleasing to the senses; in this case not a regulated or enforced guide in water treatment. carcinogenic- cancer causing substance or material disinfection-by-product- chemicals formed by the reaction of organics to chlorine or other disinfectants organics- chemical compounds containing carbon

11. Jumbo cotton balls

12. Sand

13. Water bottle

15. 1. Place the top half of the bottle upside down, creating a funnel through the drinking spout. `

16. 2. Insert mouth of the bottle to the hole of the plywood, this will serve as the base of the filter.

17. 3. Place jumbo cotton into the drinking spout of the bottle and then pour a layer of sand over the cotton, cap off.

18. 4. Next, pour the layer of activated carbon just above the sand and lastly pour the layer of small rocks.

19. 5. Cover top of the container, but leave a small hole at the center for the tubing.

20. 6. Attach water pump to your selected container/ small aquarium and the tubing to the water filter.

21. 7. Pour the dirty water through the filter and turn on your water pump. You’ll notice that, as the water repeats the filtration cycle, clearer water will be produced.

22. Results and Findings

23. As you can see from the table, the data implies that the previously dirty water becomes remarkably clean as the process of filtration repeats. Unwanted materials and particles had been removed and water now is clearer than before.

24. Testing

25. SUMMARY For our Investigatory Project which is the Improvised Water Filter, we underwent several tests and repetition of the whole filtering process in order for us to achieve our goal which is to prove that improvised water filter is really capable of filtration. We made use of sand, pebbles, activated carbon and water pump and placed them in an aquarium in order to filter the dirty water. The aquarium is where the water to be filtered is contained, the water pump pumps that water into the water filter and that water filter returns the filtered water back into the aquarium. As the water repeats the filtration cycle, clearer and cleaner water will be produced. This is a very helpful IP for the organics (the stuff that the activated carbon adsorbs) often react with other substances in the water that form disinfection-by-products that are often carcinogenic. And on the tests we did, it showed us that several cycle of filtration is needed to be able to have the cleaner water. Since, on the first cycle, the water was still dirty, eventually, the water got clearer at the 9th -15th cycle. So, at the end of our study, we proved that our product is indeed efficient in filtering water.

26. CONCLUSION Based on the results of our experimentation, we therefore conclude that Improvised Water Filter is really effective. We also conclude that the materials we used such as the carbon, sand, pebbles, etc. are definitely useful for water filtration. Though, it may take up several cycles before having a clearer water, in the end, you’ll be satisfied of the work of the improvised water filter. We can also say that improvised water filter is really a creditable thing to own. Not just it is easy to make but what matters most is the commendable performance of this kind of water filter. Lastly, we conclude that improvised water filter is not just useful and economical, it is environmental friendly.

27. RECOMMENDATION We have observed that this investigatory project is highly commendable. We have proved that the filtration process undergone by the previously dirty water becomes remarkably clean as the repeated process of filtration repeats. This investigatory project can help in the parsimonious act we need to do with regards the usage of water. This is eco-friendly since it does not release any toxins in the environment. We believe that the application of this project in every home shall contribute to the betterment of our society. Just like the way natural aquifers act, the homemade filter strains every harmful substance in the water. It removes all the bad effects of taking in dirty water. We also recommend larger volume of the elements that are needed to filter the water so that the variables would undergo a more complex approach of filtration.
