How to make your own simple water purifier, the production process of a simple water purifier

Take an empty plastic beverage bottle, cut off the bottom, plug the bottle mouth with a single-hole plug with a catheter, turn the bottle upside down, and place the washed bulking cotton, gauze, activated carbon, quartz sand, small pebbles, etc. in layers from bottom to top in the bottle to get a simple water purifier.

Experiment description: Small pebbles and quartz sand should be washed, and small pebbles and quartz sand play a filtering role. If you don't have a single-hole plug with a catheter at home, you can make a few small holes in the cap instead of a single-hole stopper with a catheter.

Why make your own? Now many brands of water purifiers on the market are still good!

If you want to drink, drink fresh water - Beijing Caucasus Biotechnology ****.

Everything has its shelf life, and once it has been a long time, it will spoil and deteriorate.

As the saying goes, flowing water is not rotten, and the hub is not beetle.

Bottled purified water loses its original freshness, so it has a strange taste.

The drinking fountain machine has changed this situation completely, filtering the running water directly, so that you and your family can enjoy the fresh and delicious pure water for the first time.

The manufacturing process of a simple water purifier is as follows:

Step 1: Make a muddy water sample first. Prepare a 2-liter bottle, pour 1 cup of potting soil, 1 tablespoon of tea granules, 1 tablespoon of cornstarch, 8 cups of water in turn, close the cap and shake the bottle until the solution in the bottle is cloudy.

Step 2: Make a filter. Prepare another 2-litre bottle, drill a small hole in the middle of the cap and screw the cap back onto the bottle.

Cut it in half at two-thirds of the bottle, the lower half of the bottle should be slightly longer than the upper half, accounting for about two-thirds of the entire bottle, so that when the upper half of the bottle is inverted on the lower half of the bottle, there will be enough distance between the bottle mouth and the bottom of the bottle to avoid the bottle mouth touching the bottom of the bottle.

Step 3: Then place the top half of the bottle upside down on the bottom of the bottle. The top of the bottle should be open facing up. The top of the unit is a filter, and the bottom is a container that receives filtered water.

Step 4: Put 4 cotton balls into the strainer and put half a dishcloth on top of the cotton balls (fold the whole dishcloth in half and cut it, take half of it).

Step 5: Place 4 more cotton balls on the dishcloth. Fold the remaining half of the dishcloth in step 5 in half and place it on a cotton ball. Place 4 coffee filters on top of the dishcloth.

Step 6: Now pour 1 3 cups of fine sand over the coffee filter.

Step 7: Pour 1 3 cups of rinsed charcoal over the fine sand.

Step 8: Continue to pour in 1 3 cups of fine sand and 1 3 cups of charcoal in turn. Then pour 1 2 cups of small gravel rinsed with water.

Step 9: Now measure 2 cups of homemade turbid water and slowly pour it over a small gravel.

Step 10: Pay attention to the water flowing out of the bottom of the filter, the filtered water has no foreign matter, and the water quality is relatively clear.

1. For mineral water bottles, cut off the bottom of the bottle with scissors and cut the bottle body to about half of it; Use scissors or a drill to drill a small hole with a diameter of 2 mm in the cap.

2. Wrap small pebbles, quartz sand and activated carbon with gauze; Turn the bottle mouth upside down, and put fluffy cotton, activated carbon wrapped with gauze, quartz sand wrapped with gauze, and small pebbles wrapped with gauze in turn.

3. Pour the sewage into the water purifier, and after the filtration is completed, compare the changes in the liquid before and after.

Note: 1. After injecting sewage into a simple water purifier, it can be observed that the filtered water is almost clear, indicating that the production of the water purifier is relatively successful and can achieve the purpose of preliminary water purification, but it should be noted that the purified water at this time is still not directly drinkable, and it is necessary to add disinfectant tablets or boil the water before drinking.

2. Continue to inject black ink into the simple water purifier, at the beginning, the filtered water is almost clear, after a period of time, the filtered water gradually turns black, and finally the color of the water before filtration. It shows that the filtration effect and deterioration of the water purifier at this time, and the main reason is that the adsorption effect of activated carbon is weakened, and it is necessary to replace it with new activated carbon.

The production process of a simple water purifier:

Prepare drink bottles, plastic tubes, washed sand, gauze, fluffy cotton bales, activated charcoal, about 20 washed pebbles, scissors, and drills.

Take a beverage bottle, cut off the bottom of the bottle with scissors, and cut the bottle to about half of the body; or one-fifth, depending on your needs; A small hole is pricked with scissors and a drill in the cap and a straw is inserted so that the liquid can flow out; If you don't have a single-hole plug with a catheter at home, you can make a few small holes in the cap instead of a single-hole stopper with a catheter. ）；Use gauze to wrap small pebbles, quartz sand, and activated carbon on the surface.

Turn the bottle mouth upside down, and put in bulking cotton, activated carbon wrapped with gauze, quartz sand wrapped with gauze and small pebbles wrapped with gauze in turn; This results in a simple household water purifier; The base of the bottle is glued to the wall of the bottle as a free-opening cap.

How the simple water purifier works:

The water source is purified by using gauze and pebbles to filter insoluble substances with large particles, quartz sand to filter insoluble substances with small particles, activated carbon to adsorb colored and odorous substances, and fluffy cotton to adsorb insoluble substances with small particles.

Simple water purifier purificationPhenomena and Analysis:

Phenomenon: After the sewage is injected into the simple water purifier, the filtered water is clear; Continue to inject red ink into the simple water purifier, at first, the filtered water is clear, after a period of time, the filtered water gradually turns red, and finally the color is the same as the water before filtration; Activated charcoal is dried and reused, and the color of the filtered water remains basically unchanged.

Analysis: The purification effect of the self-made simple purifier is better. Controlling the inflow and outflow of water can change the quality of purified water, and how long the simple water purifier can be used depends on the water consumption of each family, but the activated carbon will lose its effect after a period of use, and it cannot be recovered even if it is re-dried, and it should be replaced after long-term use.

A simple water filter can be slowed down in the following ways:

1. Take a plastic cola bottle, remove the hard seat at the bottom, drill more than a dozen small holes with a red-hot drill at the bottom of the bottle, and plug a rubber stopper with a glass conduit at the mouth of the bottle to make a filter;

2. Take another plastic cola bottle, cut off the part with a hard seat, drill a small hole in the bottle cap, use it as a water outlet, and make a container;

3. Coat a bottle 15 to 18 cm from the bottom of the bottle with a width of 3 cm of vertical Zen glue. Coat the inner wall of the bottom of the bottle with a width of 4 cm and the glue leakage. After the glue dries slightly, put the bottle A covered with a layer of gauze at the bottom into the bottle B, stick the joint of the two bottles with scotch tape, and reinforce it with a yarn rope;

4. Connect a rubber tube and rubber tube at one end of the glass conduit of the first bottle.

DIY Steps for a Water Purifier:

1. First prepare a plastic bottle, some small pebbles, fine sand, cotton, as well as scissors, straws and activated charcoal (or charcoal);

2. Cha Honghe cut off the bottom of the bottle, drill a hole in the cap, the size of the hole can match the diameter of the straw, and then pass the straw through the cap and set aside after completion;

3. Cut the gauze into a circle with scissors, the size of the circle matches the inner diameter of the bottle, and cut four pieces of circular gauze for later use;

4. Fill the bottle mouth with the required items downward, and fill cotton, gauze, activated carbon, gauze, fine sand, gauze, goose jujube pebbles, and gauze from bottom to top to complete a simple water purifier;

5. When using, inject turbid water from the upper part of the bottle, and the filtered water that flows out of the straw after filtering through layers is the filtered water.
