Different families may suffer from various water issues caused by kinds of surroundings. Sediment of rust and sand, Free residual chlorine and bad smells, high-concentrated heavy metal, water hardness are some usually-see problems found in home drinking water until now. Reverse Osmosis water filter system is becoming popular and do take effects on most water filtration requirements among so many home water filter systems yet now.
Let’s following the filtration steps of A Reverse Osmosis Water Filter System to show you why it is recognized that reverse osmosis water filter system is the best water filter system for home.
Pre Filtration: Polypropylene Water Filter
The first filter cartridge of a reverse osmosis water filter system is set as a pp spun sediment water filter made of high-density food grade polypropylene. Generally speaking, pp water filters in RO (reverse osmosis) water filter system is used to filters out most visible impurities such as sand, rust, dirt and debris. When unfiltered water flows through pp cartridges, plenty of sediments will be intercepted by fine poly fibers so as to finish the first pre filtration process.
Carbon Filtration: CTO & GAC Carbon Water Filter
Activated carbon water filter cartridges is the second filtration of ro water filter systems. It takes effects on filtering out multiple contaminants includes chlorine, pesticides, herbicides and some bad smells. There are 2 kinds of carbon water filter named CTO and GAC water filter cartridges, one is made of activated carbon block and another is made of carbon granules. 90% of Free Chlorine, Residual Harmful Chemicals and bad smells will be removed clearly with the help of carbon adsorption effects when water contact with carbon inside of the filter cartridges.
Finest Filtration: Reverse Osmosis Membrane
After polypropylene and carbon filtration, filtered water comes to Reverse Osmosis Membrane ( the essential part of a reverse osmosis water filter system ) which helps to filter out heavy metals, calcium and magnesium lead to high water hardness. Reverse osmosis membrane is a semi penetrable membrane which only allows pure water molecules to flow through so that all other substances can be blocked. At this step, heavy metals of lead, mercury, arsenic will be filtered out and reverse osmosis membrane generated purest water ready for drinking.
Post Filtration: Water Taste Improvement
The water comes out of reverse osmosis water filter system taste a little puckery, so most reverse osmosis water filter systems are equipped with post carbon water filters to improve water taste and add some beneficial minerals into filtered water. After that, water tastes better and it is good to human healthy, either.
Let’s Take A Conclusion of All Above
A lot of water filter systems are selling on the market and only focus on what puzzles you most and what you suffer most would be a fastest way to find the right water filter system you need. Thought you already have a enough acknowledgement of which home water issues a reverse osmosis water filter system can solve and then decided what kind of reverse osmosis water filter system suits you better.
