A simple way to filter water with sand and gravel, extremely clean and effective
Learn how to filter water with sand and gravel
What is the essence of how to filter water with sand and gravel? It is no coincidence that since ancient times, Vietnamese people have researched solutions to filter water with sand and gravel.
This is a method that combines with synthetic materials such as quartz sand, manganese sand, activated carbon, black sand, gravel, … and forms a closed cycle, helping to retain and return dirt. a source of clean, clear water that meets the standards of domestic water.
Learn how to filter water with sand and gravel? What filter is this?
The essence of sand and gravel water filtration is to treat upstream water, remove metal elements, impurities, and suspended particles, in other words, “summing up pathogens”.
Because of its convenience and ease of implementation, the method of filtering water with sand and gravel is always preferred by Vietnamese families, especially in geographical areas with undeveloped economic conditions such as in rural and remote areas. …
What are the advantages of sand and gravel water filtration methods?
Filtering water with sand is quite simple and inexpensive but highly effective. The source of filtered water is clean and there is no residue, impurities, and suspended substances in the water to ensure safe drinking.
What are the advantages of sand and gravel water filtration?
How to filter clean water can also remove Arsenic in water.
The water filtration system is very simple and inexpensive because activated carbon is cheap and easy to find in the market.
The use time of the filter sand is quite long, there is little need to replace the materials, it is also simple to replace, it does not cost too much. The water filter period is applied for up to 6-9 months before it needs to be replaced.
The effect of sand and gravel in water purification
To understand how to filter water with sand and gravel, you first need to understand the types and effects of the most popular “homemade filter components” today. This will also help you to see, evaluate and choose the best material for your device.
A most general way to filter water with sand and gravel, the most used types of sand and gravel when making water purifiers include:
Activated carbon
Activated carbon is an important raw material for water filtration with sand and gravel
Activated carbon is a material that is always present in modern water purifier lines, they are black, smooth as ash. The use of activated carbon is to retain suspended particles, large impurities, and a few toxic organics. Activated carbon can be used to deodorize, decolorize, and remove residual chlorine in water. Because of these properties, activated carbon is commonly used in aquariums.
Quartz sand
Arsenic is a leading toxic element in water and can be absorbed by quartz sand. Therefore, this is an indispensable element if you want to have non-toxic water. In addition to arsenic, quartz sand will also help speed up water purification, removing impurities that do not precipitate in water.
Golden sand
Yellow sand has a smaller grain size than quartz sand. The function of yellow sand in water filtration by sand and gravel is to make it clear and increase the quality of water after filtration.
Quartz gravel
Quartz pebbles help filter water cleaner
In the way of filtering water with sand and gravel with a homemade water purifier, quartz gravel is often placed at the bottom as a material for lining the bottom of the tank. Quartz gravel has the function of supporting the copper system as well as filtering in water like quartz sand.
Manganese sand
Manganese sand has the function of helping to reduce manganese, creating iron precipitates as well as reducing toxicity in water. Manganese sand usually has a rather large grain size, similar to quartz sand but darker in color.
Black sand
Maybe you still don’t know, that black sand is also an ingredient that should be in a home water purifier. They play an extremely important role in the treatment of well water contaminated with alum and iron.
Instructions on how to make an easy and simple sand and gravel water filter system
How to filter water with sand or gravel or make a water filter with sand and gravel, first, we need a large enough tank, depending on your daily water needs.
Instructions on how to make an easy and simple sand and gravel water filter system
First, you need to prepare a tank with a sufficient area. The preparation of the tank will also depend on how much capacity you want to filter the water. Then you will begin to arrange the gravel filter material as follows:
- Grade 1: Quartz gravel, quartz gravel has a large size, so it will be placed on the bottom of the tank.
- Grade 2: Quartz sand is placed about 20cm thickness is suitable.
- Grade 3: Manganese sand with a thickness of about 15-20cm, depending on the size of the tank.
- Grade 4: Activated carbon, recommended in tablet form with a thickness of 20-30cm. To minimize corrosion and washout.
- 5th grade: Quartz sand, in this layer you spread a layer of quartz sand first, then the second layer should be spread thinner about 10-12cm.
- 6th Grade: Yellow sand, as this is a layer of material that functions in water, so you should spread it at 7-10cm thick.
- Grade 7: Black sand, should be spread about 10cm thick. Since this is a layer on top, when spreading. So you need to pay attention to spread evenly, really flat. Let the water be filtered as thoroughly as possible.
Note when making a water filter system with sand and gravel
Let’s find out some tips and frequently asked questions about how to filter water with gravel.
Note on how to filter water with sand and gravel
When making a sand and gravel water filter, in addition to ensuring the quality and order of filter materials, another note you need to know is to prepare a shower nozzle. Especially for well water, this is even more urgent.
Important note when making a water filter system with sand and gravel
Because well water often contains many heavy metal ions. Water that is exposed to oxygen will then cause a reduction reaction, thereby reducing the toxicity to your water source.
Is this sand and gravel filter completely clean or not? Preliminary filtration measures are only capable of filtering out large, coarse particles.
Even though it has gone through the sand, the filtered water still has the risk of some heavy metal ions such as arsenic, manganese, lead, etc. Therefore, the filtered water should only be used for living needs. daily activity.
When eating and drinking, you still need to ensure the principle of “cooked food, drink boiling” to avoid health hazards. And if you want a standard clean water source that can be drunk directly after filtering, you can consider smart water purifier devices.
Some questions about how to filter water with sand
Frequently asked questions about how to filter water with sand and gravel that many people often wonder.
1. Is the sand and gravel filter really clean?
Are not. Because this is a simple, rudimentary manual filtration method, the filtered water will not be completely clean, which cannot be guaranteed to drink directly.
Although it is through a filter system with sand and gravel, the filtered water still contains many ammonium and nitrite compounds at high levels, in addition to many other heavy metals such as arsenic, lead, manganese, etc., which are highly toxic and cause disease. to the intestinal tract, skin, respiratory, digestive system or seriously carcinogenic.
Questions about how to filter water with sand
Therefore, the source of filtered water with sand and gravel only serves the needs of living and eating with boiled and cooked to avoid health effects.

The pool filter sand set will have a specialized design to help filter clean water, less time and effort than other forms of treatment.
In addition to filtering, swimming pool water can use pool chemicals in combination with pool cleaning to help keep the water in the swimming pool clear and free of bacteria. Currently, there are many different swimming pool water purification technologies, but the method of filtering water with sand and gravel is considered the traditional method that is optimal, superior, cost-effective and brings the highest efficiency.
Can the ash filter out alum contaminated well water?
The answer is yes. Just use about 5 to 10g of kitchen ash and put it in the pot of water to be de-alum, let it sit for about 15 minutes to 20 minutes. Kitchen ash will remove insoluble iron compounds and provide clean, safe water.
