Along with environmental pollution, the current situation of water pollution is becoming an increasingly difficult problem. Polluted drinking water seriously affects people’s quality of life and poses a risk of disease.
Water purifier is a clean water purification solution that is no longer strange to many families. The water filter equipment sold on the market is very diverse in type, model, and price. But some families with limited economic resources or want to save money have thought about self-learning how to make a mini water purifier for the family.
What are the methods of manual water filtration? What is the truth about the effectiveness and safety of “homemade” products? In the article below, Sakura Electric will help you find out the details!
Some methods of making a mini water purifier at home
Water purification equipment on the market has many types from water purifier small type, mini direct drinking water purifier to filter tanks, large capacity water purifier. However, investment in filtration systems is more or less costly.
For families who want to save money and do not have too many strict requirements in domestic water purification, they can take advantage of available materials to make their own mini water purifier. You can refer to some suggested ways to make a mini water purifier:
Biological filtration method
The biological water purification mechanism is considered the most classic and popular method of water purification. The essence of the biological water filter is the use of separate layers of substances: gravel, sand, activated carbon to retain impurities, large and small particles in the water.
This is also the mechanism of water filtration in nature to create clean groundwater, when rainwater seeps into the rocks, sand and gravel layers.
How to make a mini water purifier based on the living filter method is quite simple. Materials required include: Gravel, sand, activated carbon, a 3-compartment container, plastic pipe, hole saw.
>> Detailed instructions on how to make a biological water filter:
Step 1: Handle the water tank, put the water tank upside down
Step 2: Drill holes in the bottom of the barrel and proceed to put in layers of materials: gravel, sand, activated carbon.
Choose activated carbon as the bottom filter because they have the ability to filter the smallest impurities, disinfect, deodorize, and mold.
Next, pour sand in to form a filter in the middle. The sand layer has the ability to remove impurities of moderate size.
Pour the top layer of gravel, this layer is responsible for filtering large impurities: dirt, leaves, small organisms.
Step 3: Pour water into the jar to start filtering
The advantage of making a mini water purifier based on biological methods is that it is easy to implement, the materials are cheap and safe. The source of domestic water passes through the layers of impurities that are naturally filtered, eliminating pathogens, without chemical treatment. This is a method any family can do!
Filter method using charcoal
Similar to the above domestic water purification mechanism, the only difference is that this method uses charcoal instead of activated carbon. The effect of making this mini water purifier is similar to the activated carbon domestic water filter. Therefore, if your family has charcoal materials available, they can be used instead.
The method of filtering using charcoal is easy and convenient, you can also remove a layer of gravel if you use charcoal instead of activated charcoal. Materials to prepare simply include: charcoal, sand, plastic bottles, some pieces of cloth.
>> How to assemble a water purifier using charcoal:
Step 1: Use an upside-down plastic bottle wrapped with cloth on one end
Step 2: Cut the bottom of the bottle and put it in layers of charcoal, thick sand
Step 3: Pour filtered water into plastic bottles
The disadvantage of this method is that the filtered water has a matte black color that cannot be used immediately due to the influence of charcoal. Therefore, how to make a mini water purifier using appropriate charcoal is a preliminary step to filter poor quality domestic water. If you want to filter drinking water directly, you should still use an RO water purifier.
Distilled water method
This is one of the safest “homemade” water purification methods, suitable for families with young children. This water purification mechanism not only helps to remove impurities but also has the ability to retain hydrogen and oxygen for water.
Making a mini water purifier from distillation requires some more complicated materials: a kettle, a kettle, a heat-resistant water pipe, and a water tank.
>> Steps to filter distilled water:
Step 1: Use a heat-resistant water pipe to connect the kettle to the water tank so that the two ends are sealed. Note that the water tank must be placed lower than the kettle
Step 2: Pour water into the kettle and cook until it evaporates
Step 3: Recover the distilled water in the bottle
Filter tank method
One of the popular ways to treat domestic water with a small to large capacity. In essence, the filter tank method is completely similar to the biological self-filtration mechanism mentioned at the beginning of the article. However, instead of using plastic bottles and plastic bottles, this method uses a filter tank with more layers of substance.
The structure of a filter tank includes:
Layer 1: Gravel of all sizes at the bottom of the tank is 10cm thick
Layer 2: Golden sand or specialized quartz layer 25 – 30cm thick
Layer 3: Activated carbon layer with the function of removing color, odor and organic impurities
