The quality of your water supply will suggest how many stages of purification would go in the process so that you can get the best clean water to drink and cook in your home. Purifying water is a multi-filtration process where various harmful sediments are passed through several membranes to give you clear water. There are many types of water purifiers that have several different purposes as well as requirements of their own. RO and UV systems require electricity and are able to eliminate inorganic compounds and the smell of contaminated water. While activated carbon and sediment cartridge filters get rid of foul odour and sand, they do not require electricity but are ineffective in removing inorganic salts. In This post, we share with you 4 important factors to consider before you buy a water purifier.
1. Water Quality
Mostly the water supplied to your home is hard water and that means your home water has a high amount of TDS. Total dissolved solids in water contain inorganic salts such as calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates. The best water purifier to get rid of these inorganic compounds is an RO (reverse-osmosis) system. An RO membrane’s pore size is .0005 micron and makes it impossible for the dissolved solids to exist in your drinking water.
Contaminated water contains heavy metals such as lead, arsenic, magnesium, copper and iron, and they can be toxic if taken in large amounts. Due to the increase of factories and growth of city infrastructure, these metals are found more in abundance in water. Nitrate contamination is also a cause for great concern. Not only is it a result of agricultural processes but also where fishes generally live. In reverse osmosis, the dissolved and suspended impurities get reduced hence, it is advisable to get an RO system. One more kind of filter you could look at is an ultraviolet (UV) filter where the water gets disinfected. In a UV filter the harmful microorganisms cannot multiply with the radiation from the UV lamp. You can also look for an RO based UV purifier. Another method of purification is the combination of an RO and a UV filter with an ultra-filter (UF) which helps in removing suspended bacteria and is best when the water supply is free from TDS. There are also some RO systems with mineral cartridges for areas with high TDS content.
3. Water Pressure
The incoming water supply flow determines which filter you should get. A reverse osmosis system would work properly with high water pressure. Water pressure is dependent on the elevation of your building and other factors like blocked pipes and clogged filters. Water purifiers generally need a pressure of 5-40 pounds per square inch (psi). A booster pump can also be attached with an RO system if the water supply in your home has less water pressure. Otherwise, you could go for an activated carbon purifier if your water supply has less TDS.
Electricity plays a vital role when it comes to water purifiers. Many do not work without electricity and they are useful for homes with bad power shortages. An ultraviolet (UV) filter would not work if there is no electricity, as it uses electricity to produce ultraviolet radiation that eliminates bacteria. An RO system would not work without electricity as it uses electric power to provide enough water pressure for the RO membrane. Activated carbon purifiers don’t require electricity just like sediment filters and ultra-filters (UF). While RO and UV systems remove TDS and bacteria that cause water borne diseases, the non-electric purifiers can only get rid of some of the chemicals dissolved in water, along with germs and sand. It is advisable to opt for water purifiers that run on electricity.
Now that you have gathered some information on the conditions and the differences between electric and non-electric water purifiers, we hope that you are able to come to a decision of getting yourself the perfect water purifier based on your needs.
