DIY Water Filtration System – Simpleng Paraan ng Pagsasala ng Tubig

💧 DIY Water Filtration System – Simpleng Paraan ng Pagsasala ng Tubig

Panimula:
Ang malinis na tubig ay mahalaga sa ating kalusugan. Sa proyektong ito, matututuhan ng mga estudyante kung paano gumagana ang natural na proseso ng pagsasala o filtration. Gamit ang mga simpleng materyales, makakagawa sila ng sariling water filter na nagpapakita kung paano nalilinis ang maruming tubig.

Mga Kagamitan:

  • Plastic bottle (1.5L)
  • Gunting o cutter
  • Buhangin (fine at coarse)
  • Graba o maliliit na bato
  • Uling (charcoal)
  • Cotton o tela
  • Maruming tubig (para sa testing)
  • Baso o lalagyan ng output water

Paraan:

  1. Putulin ang bote sa gitna at gawing parang imbudo ang itaas na bahagi.
  2. Ilagay sa ilalim ng bote ang cotton o tela bilang unang layer.
  3. Sunod na ilagay ang uling, pagkatapos ay buhangin, at sa ibabaw ay graba.
  4. Ibuhos ang maruming tubig sa itaas na bahagi ng bote.
  5. Obserbahan kung paano lumalabas ang mas malinaw na tubig sa ibaba.

Paliwanag:
Ang bawat layer ng filter ay may kanya-kanyang tungkulin:

  • Graba – sumasala sa malalaking dumi.
  • Buhangin – sumasala sa mas maliliit na particle.
  • Uling – tumutulong alisin ang amoy at ilang impurities.

Bagama’t hindi ito ligtas inumin agad, ipinapakita nito ang basic principle ng water purification — ang proseso ng pag-aalis ng dumi sa tubig upang maging mas malinis.

Konklusyon:
Ang paggawa ng DIY water filtration system ay isang magandang paraan upang matutunan ng mga estudyante ang kahalagahan ng malinis na tubig at ang simpleng agham sa likod ng filtration process.

DIY water filtration system made from a plastic bottle filled with gravel, sand, and charcoal filtering dirty water.

💧 DIY Water Filtration System – A Simple Way to Purify Water

Introduction:
Clean water is essential for life. In this project, students will learn how the natural filtration process works using basic household materials. They will create a simple water filter that demonstrates how impurities can be removed from dirty water.

Materials Needed:

  • 1.5L plastic bottle
  • Scissors or cutter
  • Fine and coarse sand
  • Gravel or small stones
  • Charcoal
  • Cotton or cloth
  • Dirty water (for testing)
  • Glass or container for filtered water

Procedure:

  1. Cut the bottle in half and use the top part as a funnel.
  2. Place cotton or cloth at the neck of the bottle.
  3. Add a layer of charcoal, followed by sand, and then gravel on top.
  4. Pour the dirty water into the filter.
  5. Watch as cleaner water comes out at the bottom.

Explanation:
Each layer plays an important role:

  • Gravel filters large debris.
  • Sand removes smaller particles.
  • Charcoal absorbs odor and some impurities.

Although the water may look clean, it still needs boiling or chemical treatment to be safe for drinking. This project demonstrates the basic principle of water filtration.

Conclusion:
Creating a DIY water filtration system helps students understand environmental science and the importance of clean water in daily life.
