Buying Guide for Domestic Water Purifier

By | July 15, 2022

Water purifiers remove contaminants from water, making it more reliable for us to drink. Water purifiers can also destroy biological contaminants and remove certain minerals from water. They collect contaminated raw water, filter impurities such as sediments and microorganisms and then deliver it clean water.

Different water purifiers have different functions and hence the water purifier price in Bangladesh varies.

Viruses and microorganisms that cannot be removed by filtration, can be removed with a cleaner. To kill or capture viruses, some cleaners use chemicals, while others use an electrostatic charge.

The removal of unwanted chemicals, biological pollutants, suspended solids, and gases from contaminated water is called water purification. The idea is to create water suitable for a specific use. Although most water intended for human consumption (drinking water) is disinfected, it can also be adapted for a variety of other uses, such as B. to meet the needs of medical, pharmaceutical, chemical and industrial applications.

Physical processes such as filtration, sedimentation and distillation are used; biological processes such as slow sand or bio-activated carbon filters are used; Chemical processes such as flocculation and chlorination are used, and electromagnetic radiation such as ultraviolet light is used. 

Benefits of water purifiers

Allows to maintain good health 

Since water makes up more than 80% of our body, it is the axis around which our well-being and overall well-being revolve Water purifiers ensure that our bodies only consume clean and pure water, free from pollutants and impurities.

Benefits our surroundings and finances

Plastic bottles filled with drinking water and other uses generally end up as waste products, sometimes accounting for up to 65% of total waste. A water purification system saves you money and the environment by eliminating the need to buy bottled water, and cans. Filtered water is cheaper than bottled water because shipping costs are not included.

Protects from harmful toxins

Water can be obtained from various sources. Municipal water is available in cities and towns. However, the quality of this water varies from place to place. They are commonly used for washing, cooking, and other household chores. , if not properly handled or cleaned, they may not be entirely safe to drink. Filtration alone cannot remove dissolved chemicals and toxins.

Protection against germs 

Diarrhoea, abdominal cramps, constant vomiting and fever are just a few of the ailments that can be caused by parasites such as e-coli, bacteria and cysts. Modern water purifiers can effectively remove a large percentage of impurities and metals contained in drinking water, such as zinc, aluminium, mercury, lead and copper.

Buying guide for water purifier 

Buying a water filter may seem like an easy task, but it is not. The following variables will help the consumer decide what type of water purification system to purchase:

Quality of Water

If your home water supply has high levels of dissolved solids (TDS), hardness, or salinity, reverse osmosis (RO) is the best option. Reverse osmosis uses a semi-permeable membrane that can filter out even the smallest amounts of dissolved salts, metals and impurities. Activated carbon filters can also be effective in other situations. Some of the most harmful contaminants in water include bacteria, nitrates, dissolved pesticides and lead. Any laboratory can analyze the number of contaminants present in the water. Therefore, if your home water has high levels of microorganisms and contaminants, UV-based reverse osmosis filtration may be the best option. The action of UV rays irradiates the water and penetrates the cells of bacteria and viruses, preventing their multiplication. These organisms cannot reproduce, and will eventually die. The RO membrane cleans the water of these dead microorganisms and impurities, making it drinkable.

Water Pressure

You should check that your home plumbing system has enough pressure while pumping water. UV and RO filters need a high-pressure water source. RO filtration will not function properly if the water flow it receives is not of sufficient pressure to the height of your building, as well as other factors such as clogged filters and clogged pipes.

Purification system based on contamination levels – 

Water with high TDS content (500-2000 PPM) is treated with reverse osmosis purifiers (or reverse osmosis purifiers). -If your water contains bacteria, viruses, or microorganisms that cause waterborne diseases, UV purifiers are used. Universal Purifiers integrate many technologies, such as reverse osmosis, ultraviolet, and activated carbon to produce 100% pure water. Gravity water purifiers clean water by gravity and are suitable for low TDS water needs electricity.

Electricity

When it comes to water purifiers, electricity is key. Many cannot function without electricity, making them ideal for homes experiencing severe power outages. If there is no electricity, a UV filter will not work as it relies on electricity to produce UV light. The Light that kills microorganisms. An RO system will not function without electricity as it relies on delivering enough water pressure to the RO membrane. Activated carbon cleaners, such as sediment filters etc. Ultrafilters, do not require energy (UF). Non-electric cleaners can only remove some of the compounds dissolved in water, as well as germs and sand, while RO and UV systems can remove TDS and microorganisms that cause waterborne diseases. Electric-powered water purifiers are the best option.

Parts Availability 

The markings occasionally indicate that a water purification product has been withdrawn from the catalogue and replacement parts are no longer available. In such cases, you need to use inferior parts or buy a new water purifier. As a result, you have to choose another model from any manufacturer and ask how long that model will be supported for spare parts.

End Words

Although water contains numerous minerals that are beneficial to the human body, ingesting too much water can cause a variety of ailments. An excellent water purifier will remove excess salts, suspended matter and bacteria while preserving the important vitamins and minerals in the water. With so many companies in the water treatment market these days, it’s hard to tell which are good, which aren’t, and which meet the minimum requirements. Another important factor that you need to consider is the price of water filters in Bangladesh.
