Tips on What is Reverse Osmosis and What Does it Do?
What is reverse osmosis? Also called hyperfiltration, reverse osmosis is a commonly used water filtration system. While it was considered to be a fantastic invention in its time, it has now been superseded by more up to date and effective filter systems. Despite this fact, many water filter makers continue to use and market reverse osmosis as the leading form of water filtration. This is because it is relatively cheap to manufacture.
What does reverse osmosis (RO) do?
RO uses a semi-permeable membrane to filter out microorganisms while allowing water to pass through. It only filters contaminants that are larger than the membrane pore size which can vary between filter systems.
Advantages of reverse osmosis filtering
Reverse osmosis can remove a range of contaminants in drinking water through pores of 0.0005 micron in size.
Disadvantages of reverse osmosis filtering
Some reverse osmosis systems use Thin Film Composite (TFC) membranes which are susceptible to degradation by chlorine that is found in water. Reverse osmosis systems then must contain carbon pre-filters which can add to the cost considerably.
The membrane quality of cheap reverse osmosis systems are poor and do not filter out enough contaminants.
For customers, reverse osmosis can end up costing a lot of money in the long run as you are required to change the membrane filters regularly and these are expensive.
To prevent membrane fouling and to keep the system functioning optimally, RO systems need sediment and carbon pre-filtration and regular replacing of filters which can get expensive. RO can also be slow and produces only 15 gallons of water per day. Another major disadvantage to reverse osmosis is the water wastage issue. It can take up to 10 gallons of untreated water just to make one gallon of filtered water. This is an incredibly inefficient way to filter water.
There are alternative methods available to the consumer. These alternatives use a combination of filtering methods including the highly effective ion exchange method. This is believed to reduce microorganism particles considerably when compared with reverse osmosis. A higher throughput is also possible, with production of up to 30 gallons of water per day, more than double that of reverse osmosis systems.
In conclusion, while reverse osmosis systems are popular in homes, they are not always the best choice for a home filter system and you are advised to look past the initial cost to determine the long term viability of such systems. Do your research, and find the best system to meet your needs.
