Reverse Osmosis (RO) is an advanced and widely accepted technology for water purification. With its popularity in the domestic sector, it is a preferred solution for high salinity water, to deliver fresh, tasty and safe drinking water for our households. Due to increased industrialization, risk of impurities (chemical and microbial) found in the water sources is high. Hence it is important and necessary to use an RO water purifier for a healthy life.
What is a RO Water Filter System & How Does It Work?
Reverse Osmosis uses a semi-permeable membrane, the pore size of which is 0.0001 micron. It is a separation process that retains the contaminants on one side and allows the pure water to pass on the other side of the membrane.
The booster or high pressurized pump, which is an integral part of RO water purifier, pressurizes the water with impurities through the RO membrane. Further, pure water is permeated through one stream and impure water is rejected through reject stream.
Benefits of RO Water Filtration
Pro #1: Removes Majority of Contaminants
Reverse Osmosis effectively removes 90 to 95% of the dissolved salts (ions) thereby improving the taste of water. It also removes disease-causing bacteria and viruses; heavy metals, chemical contaminants like trihalomethanes, VOC’s and pesticides. RO is an effective technology to treat surface water, city water and groundwater.
Pro #2: Ease of Automation & Maintenance
Once installed, the RO system works automatically without any assistance. Only requires changing the filters periodically. To add, most filters require a replacement once in every six to twelve months. The life of RO membrane can be as high as 1 to 2 years depending on the inlet water quality.
Pro #3: SMPS technology-based
The Zero B RO water filtration uses SMPS based technology which ensures reduced power consumption, improved efficiency and overall performance of the water filter system.
Drawbacks of RO Water Filtration
Con #1: Water Wastage is high
One of the drawbacks of this technology is that it leads to wastage of water while delivering pure water. It generally wastes as much as 75% of water in the reject and delivers only 25% of pure water.
Con #2: Recontamination of purified water
Purified water in the tank can get contaminated due to build-up of slime forming bacteria or due to loophole in the RO membrane some microbes may get mixed and thus leaves water untreated. Hence back-up for RO purification is inevitable.
Con #3: Requires periodic Sanitization
After extensive use or not in use, there may be build-up of bacteria over the tubing and rest of the tank. You get foul smell to the water. To tackle this problem sanitization with oxidizing chemicals like chlorine and hydrogen peroxide is required.
In Conclusion, a RO water filtration system is an advanced water purification technique with its share of pros and cons. Now, it depends on you to decide whether it is an excellent long-term investment for your house or not.
