Clean and safe water has become the need of every household in today’s time. Keeping this need in mind, Gravity-based Water Purifier has emerged as an easy and reliable solution.
This purifier works without electricity and filters water through its simple gravity system. In simple words, Gravity-based Water Purifier is an easy way to make your everyday water clean, safe and drinkable.
In this article, you get to know how Gravity-based Water Purifier works, its benefits, types, and tips to maintain it for safe and clean drinking water.
How Gravity-based Water Purifier Work?
The working method of Gravity-based Water Purifier is quite easy and natural. It does not require electricity, because it cleans the water by pulling it from top to bottom with the pressure of gravity.
Let’s understand it step-by-step:
- Putting water in the upper container – First of all you pour raw water (tap water or stored water) in the upper tank.
- Passing water through the filter – Due to gravity, the water is slowly pulled downwards and during this time it passes through sediment filter, activated carbon filter or UF (Ultrafiltration) membrane. This removes dust, soil, chlorine, dirt and many harmful microorganisms.
- Collection of pure water – After passing through the filter, clean and safe water gets collected in the lower tank, which you can use directly for drinking.
Note: No motor or electricity is used in this entire process, rather the weight of water and gravity make its work easy. This is why this technology is very suitable for rural areas, homes with lack of electricity and outdoor use.
Main Components of Gravity-based Water Purifier
Gravity-based Water Purifier has many parts which together give you clean and safe water.
- Upper Storage Tank: You put raw (impure) water in it. This tank is usually made of transparent or strong plastic so that the water level can be easily seen.
- Sediment Filter: This filter removes dust, sand and large particles from the water. Due to this, there is not much burden on the next filter.
- Activated Carbon Filter: It improves the taste of water, removes odor and reduces chemicals like chlorine.
- UF or Microfilter Membrane: It is a very thin membrane-like filter that prevents bacteria and microscopic impurities.
- Lower Storage Tank: Clean water collects here, which you can drink directly.
All these parts work together to clean water using natural gravity without the use of electricity, giving you fresh and safe water every day.
Important Points to Remember:
- It is important to clean or replace the filter from time to time.
- Always fill the upper tank with water from a clean vessel.
- Wash the lower tank regularly as well so that bacteria do not accumulate.
Benefits of Using Gravity-based Water Purifier
Gravity-based Water Purifier is an easy and cost-effective way to get clean water. It has many benefits that make it perfect for homes and small offices.
- No electricity or plumbing required: It works without electricity and continuous water supply, so you get pure water even during power cuts.
- Portable and easy to use: Its design is lightweight and compact, so you can easily store or carry it anywhere.
- Retains essential minerals: It does not remove essential minerals from the water, keeping the water healthy.
- No water wastage: There is no wastage of water in this process, so it is eco-friendly.
- Low maintenance cost: Its filter replacement cost is very low and maintenance is easy.
Important Takeaways:
- This is a great option for rural areas, hostels, or areas with power cuts.
- If your water has a lot of chemicals or heavy metals, this won’t be enough—an advanced water purifier is better for that.
Limitations of a Gravity-based Water Purifier
Gravity-based Water Purifier is convenient in many ways, but it also has some limitations, which are important to know.
- Not suitable for water with high TDS: If your water has high salt or hardness, this purifier will not be able to clean it.
- Does not remove dissolved salts and heavy metals: The filters in it only remove bacteria, dust and odor, but not dissolved metals like arsenic or lead.
- Slow purification process: It does not use electricity, so it takes more time to filter water, especially when the volume of water is high.
Remember Before You Decide:
If the water in your area looks clean but does not have chemicals or high salt, then Gravity-based Water Purifier is a good option. But if the water is too salty or polluted, it would be better to choose RO or UV purifier.
Who should use Gravity-based Water Purifier?
Gravity-based Water Purifier is a great option for people who already have access to relatively clean and low TDS water.
- Homes receiving municipal treated water: If you get pre-purified municipal water, this purifier will easily remove bacteria and dust.
- Rural areas where there is no electricity: This purifier is very useful where there is a shortage of electricity but the water is not too salty.
- Tenants or people who change houses frequently: It is lightweight and portable, so it can be easily carried anywhere.
Make an Informed Choice:
If you want a purifier that is not dependent on electricity, is easy to use and retains essential minerals, then Gravity-based Water Purifier can be the right choice for you.
Conclusion
Gravity-based Water Purifier is an easy, cost-effective and power-free way to get clean water. It filters water using gravity, removing impurities like dust, bacteria and odors. It has many advantages like easy portability, retaining essential minerals and low maintenance cost. However, it cannot remove high TDS (hard) water or dissolved salts and heavy metals.
So, make sure to test your water quality before buying. If you have municipally treated or low TDS water, a gravity-based water purifier is a reliable and convenient option.
