How To Make The Best Water Filters

Design and build a device that tin make clean a dirty water sample using materials around your home. You lot'll follow the same design process used past NASA engineers and scientists when they developed the h2o filtration system for the International Space Station orbiting World. To do then, you'll apply an iterative procedure, meaning you'll test multiple designs, look at how your materials become y'all closer to your goal, and record your findings to build the best filter possible.

Important safety notation! This action is not designed to make drinkable h2o. No thing how "clean" your filtered water looks, you should never beverage it considering it all the same may incorporate pollutants y'all can't meet.

In this episode of Learning Space, y'all'll use materials from effectually your dwelling to build a device that tin can clean a muddied water sample like the h2o filtration system on the International Space Station. | Lookout on YouTube

Materials

one-two empty plastic h2o bottles

Scissors

Towel or paper towels (for spill clean upwards)

Cheesecloth or gauze to cover the mouth of the bottle

Condom bands

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

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

ane. Create a dirty water sample

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

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

2. Build your filter cartridge

Until a few years ago, water 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 so that water could be cleaned and reused onboard the space station.

To build your ain filtration system, you'll need a filter cartridge. Start by advisedly cutting your water bottle in one-half, beyond 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. Plough the top half of the canteen upside down (so the function with the cheesecloth or gauze is facing down) and place it into the bottom half of the canteen.

If yous want to fit more materials in your filter, you tin can apply two bottles. You can likewise utilize larger bottles or attempt other containers. Notation: Clear containers will help y'all see the filtration as it takes place.

three. Design your filter

The filtration organisation on the space station has several stages that starting time filter out larger droppings, and then smaller impurities and even bacteria. You lot may want to use similar layers in your filter.

Mix or layer the filter materials you've nerveless in the pinnacle of your filter cartridge. Write down what filtration materials y'all use and how much.

4. Exam and evaluate the results

Cascade your fake wastewater into your filter and observe the water that comes out at the bottom of the filter. How constructive was your filter at cleaning the water? Write down what you notice. How long did information technology take to filter the water? What worked well? What could be improved?

Important prophylactic note! No matter how "clean" your filtered h2o looks, you should never drink it because it nonetheless may incorporate pollutants you can't see.

five. Revise and endeavor, try again!

Revise your filter based on what you saw during the concluding step. So, test it again. Consider using the same amount of wastewater for each test so you can meliorate evaluate how well your filter is working not just in terms of the colour of your filtered water, only how much you're able to clean, or reclaim.

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

Equally you revise, you'll notice that some filter materials piece of work better than others – non merely at filtering out solids like dirt, merely as well in removing colors. Proceed redesigning and testing your filter. Your goal is to produce as much clean water as possible during a single time through the filter.

Remember: Practise not drink the dirty or filtered water!
