How to filter water with sand effectively for the family

Sand filtered water is one of the very popular ways to clean domestic water. Especially, water from drilled wells in some localities is heavily polluted. So what is water filter by sand? Learn the effect and the extremely simple sand water filtration method that we have synthesized through the article below!

1. What is sand filtration?

Water purification by sand is a method of using sand as the main material to filter water, helping to remove impurities and impurities in the water. Normally, people will not use only sand to filter water, but often combined with some other filter materials such as gravel, activated carbon, manganese sand, quartz sand, ...

Currently, water filtration by sand and coal is mainly used to filter water sources from drilled wells and wells in localities, rural areas that do not have tap water, clean water for domestic use because The investment for this method is quite low.

2. The effect of sand filtration

  • Sand water filtration is a simple but highly effective method of water filtration. Some of the main effects of this method are:
  • Helps remove organic substances such as pesticides, pesticides and heavy metals contained in water such as iron, sodium, ...
  • Removal of cations or anions helps balance the substances in the water while sweetening and softening the sucrose.
  • Reduces iron and arsenic in water, helps to stabilize the pH of the water within a safe range, reducing the oil content
  • Remove excess fluorine and heavy metals in water such as copper, zinc, chromium, nickel ...

3. Learn how to filter water with sand

As mentioned above, when using the sand water filtration method, we need to combine with some other filtration materials such as gravel, stone, activated carbon and nuts, .. to achieve the best filtration effect.

3.1. The order in which these materials are arranged from bottom to top
  • The bottom layer will be a large size gravel to create a hollow slot for the water pipe to be filtered into the tank.
  • Next is the small upper gravel layer, these 2 gravel layers mainly work to create transparency for the water.
  • Above the small gravel is a large layer of golden sand
  • Next is the activated carbon layer, usually using activated carbon in pellets and cylinders. This activated carbon layer usually has a thickness of 15 - 20 cm
  • Above the activated carbon layer is a layer of golden sand is treated with a small size, no gravel
  • On the top is a layer of black sand that removes large-sized dirt and impurities while preventing erosion of the underlying materials when exposed to the flow.

3.2. Advantages of sand filtration

  • Sand water filtration brings high efficiency, the water source will be completely removed from dirt, impurities, suspended substances in the water.
  • This method is considered to be able to remove arsenic in water
  • Cost savings because the prices of activated carbon and sand in the market are quite cheap and easy to find
  • Time used for quite a long time, less need to replace materials but the replacement is also quite easy. Can be used from 6 to 9 months to replace materials 1 time

4. Questions about sand filtration

  • Can sand filter remove heavy metal?
A small part can be eliminated because this is a fairly simple and rudimentary method of filtration. To completely remove harmful substances you should add a variety of filter media. Therefore, water filtered by sand should only serve as living needs such as bathing, washing, watering plants .. when used for eating and drinking, it is necessary to boil or filter through once with a water filter.
  • Should sand be used to filter well water?

Have. The application of this method will help to remove a part of large pollutants before using other methods to completely treat heavy metals, viruses, and bacteria in small sizes in water.

  • How often should the sand be changed?

The time to wash and replace sand depends a lot on the pollution level of the water as well as the filter flow. Usually, the sand replacement time will be from 5 to 6 months. However, you should rinse to clean the sand every 3 months.

Above is how to make a sand filter tank and some simple filter materials that we want to share with you. Although it is quite effective to improve the water source in daily life, this method cannot give the standard water source to drink directly. Therefore, we should boil water before using it to avoid bacteria and viruses remaining in the water.

If you find that how to filter water with sand and some other filter materials is good, please share it so everyone knows and minimize the lack of clean water in daily life quite worrying!
