There are lots of contaminated impurities present in the water that are hazardous to us. Most of the time the water is purified from the regular tap water and thus it is very important that the impurities from the drinking water are removed, and the additional contamination is managed properly. There are different types of purifiers available in the market, and so are the technologies. Water purification technologies range from simple to advanced purification system, and here we will discuss the best 5 advanced water purification technologies that are being used in different types of water filtration systems such as Faucet Water Filters use Ion exchange or activated carbon technology. Some more powerful ones use reverse osmosis. So, in this post, you will read more about these technologies.
Best5 advanced water purification technologies
Reverse Osmosis Technology
Though Reverse Osmosis (RO) is a technology, it is so famous and widely used water purification method that in common conversation we call the water purifiers as ROs. It is also one of the most economical water purification methods. Reverse Osmosis uses high-pressure membrane technology to remove dissolved impurities, chemicals and germs from the water. In this system, the membrane has very fine pores (slightly larger than the size of water molecule) that allow only water to pass through and the harmful chemicals, ionic impurity, most organic impurity, and nearly all particulates, bacteria and bio-molecules are removed from the filtrate or permeate water; these are carried out of the RO module in a waste or concentrate water stream. And thus, the semi-permeable membrane requires care and maintenance on a regular basis.
Ion Exchange Technology
Ion exchange is the exchange of ions between ionized species in the water with ion exchangers such as H+ and OH- ions. The procedure is reversible and the column can be redeveloped by washing down the excess ions. Water is passed through beds of ion exchange resins where the ions in the solution travel into the beads. Here, as a function of their relative change thickness, they compete for the exchange sites.
Ultra-filtration, also known as sub-micron filtration fundamentally works in the same way as a strainer and offers a physical blockade based on pore size to the passage of particles in purified water systems. It uses membrane filters having a pore size of mainly 1 to 10 nm that can remove the smallest of the particles. Ultra-filtration is an amazing technology that ensures a consistent ultrapure water quality with respect to particles, bacteria, and pyrogens, etc. The water flow is either directed straight through the membrane or in a ‘cross-flow’manner, where a little amount of the input water flows across the membrane surface to reduce pollutants by rinsing away the contaminants.
Ultra-filtration usually fixed near the outlet of a water purification system so that the concentration of microorganisms and large organic molecules could be reduced. These filters should regularly be maintained simply to make sure that they are working effectively.
Ultra-violet (UV) Technology
UV water purification technology uses ultra-violet light to kill the germs, bacteria, micro-organisms, etc. present in the water. Ultra-violet water purification system is a simple yet effective process that claims to kill almost 99% of the harmful micro-organisms present in the water. A minute mercury lamp is placed in the purifier that generates short-wave UV radiations. These radiations irradiate the water and break through the cells of bacteria and viruses. This process destroys the ability of micro-organisms to reproduce and thus they could not multiply and eventually die. This purification method only kills the germs, but the separate filter is required to eradicate the germs. Also, it only removes the germs from the water, but if there are some other contaminants present in the water, the UV light can’t remove those impurities, and even the micro-organisms covered under those impurities can also remain alive. So, UV water purification is usually done in combination with other filtration technologies such as reverse osmosis (RO) or activated carbon filters.
Activated Carbon Technology
This water purification technology uses activated carbon filtration process. The carbon filters are able to remove a lot of chemicals impurities like chlorine, pesticides, and other impurities. But in this filtration process, the taste and odor of the water change. You don’t need electricity to operate the filters. Also, it is also not considered very effective in removing microorganisms from the water.
Though there are a lot of water purifiers available in the market that provide a combination of 2 or more technologies mainly to ensure that maximum impurities could be removed from the water to make it safe and healthy for you, you should also do your part of research before going for a particular filtration technology as your water purifier.
