How To Make A Water Filter At Home In Two Buckets

Blueprint and build a device that can make clean a dirty water sample using materials effectually your dwelling. You'll follow the aforementioned design procedure used by NASA engineers and scientists when they developed the water filtration arrangement for the International Space Station orbiting Earth. To do so, yous'll use an iterative process, pregnant you'll examination multiple designs, look at how your materials get you closer to your goal, and tape your findings to build the best filter possible.

Important condom note! This activity is not designed to make drinkable h2o. No affair how "make clean" your filtered water looks, yous should never drink it considering information technology still may contain pollutants you can't meet.

In this episode of Learning Infinite, you lot'll use materials from around your home to build a device that can make clean a dingy h2o sample like the water filtration organisation on the International Space Station. | Watch on YouTube

Materials

1-2 empty plastic h2o bottles

Scissors

Towel or paper towels (for spill clean up)

Cheesecloth or gauze to cover the mouth of the bottle

Safety bands

Any materials you think will brand a great filter (cotton balls, sand or gravel, uncooked pasta noodles, coffee filters, etc.)

*Don't worry if you don't take all of the materials. Get creative and substitute materials with what you accept! It's all part of the design process.

i. Create a dirty h2o sample

Start by preparing the water you're going to filter. This can be done in many means that alter how difficult it is to filter the water. For example, mix some soil or dirt with tap water for an easier challenge. Try also adding food coloring or vinegar for a bigger challenge.

This dirty h2o sample volition simulate wastewater. On the infinite station, this wastewater is made up of everything from the fuel that powers the station to astronauts' sweat.

ii. Build your filter cartridge

Until a few years ago, h2o needed to sent up to the space station in big containers the size of duffel bags. But in 2010, a filtration arrangement was installed that made it and so that water could exist cleaned and reused onboard the infinite station.

To build your own filtration system, yous'll need a filter cartridge. Showtime by carefully cutting your water bottle in one-half, across the width of the bottle. Remove the cap from the bottle. Put gauze or cheesecloth over the opening and secure it with a rubber band. Turn the top one-half of the canteen upside downward (so the function with the cheesecloth or gauze is facing down) and place it into the bottom half of the bottle.

If you want to fit more materials in your filter, y'all can use ii bottles. Yous can besides utilize larger bottles or endeavor other containers. Annotation: Clear containers will assist you lot see the filtration as it takes place.

3. Design your filter

The filtration system on the space station has several stages that beginning filter out larger debris, and so smaller impurities and even leaner. You may desire to use similar layers in your filter.

Mix or layer the filter materials you've collected in the top of your filter cartridge. Write down what filtration materials you use and how much.

4. Test and evaluate the results

Pour your simulated wastewater into your filter and discover the h2o that comes out at the bottom of the filter. How effective was your filter at cleaning the water? Write downwards what yous notice. How long did it take to filter the water? What worked well? What could exist improved?

Important safety note! No matter how "make clean" your filtered water looks, you should never drink information technology because it nonetheless may contain pollutants you lot can't run across.

v. Revise and try, try again!

Revise your filter based on what you saw during the last stride. Then, test it over again. Consider using the aforementioned corporeality of wastewater for each examination so you tin can improve evaluate how well your filter is working non just in terms of the color of your filtered water, but how much you're able to make clean, or repossess.

The filtration arrangement on the space station reclaims 93% of the water onboard. Every drop counts!

Every bit you revise, you'll find that some filter materials work better than others – non but at filtering out solids like dirt, simply as well in removing colors. Go along redesigning and testing your filter. Your goal is to produce as much clean water as possible during a single fourth dimension through the filter.

Remember: Exercise non drink the dirty or filtered water!
