What is RO - Reverse Osmosis system?
Posted by John Smith on July 21st, 2017
Reverse Osmosis is a method of water purification which uses membrane technology. TFC membranes which are think film composite membranes are used to force water through a semi permeable membrane which filters out any impurities.
The three stages of RO
- The Pre Filter Stage
This is the first stage of the entire RO process and involves the removal of sediments and particulate. This is important because sediment and particulate can ruin the filter.
- The Membrane Stage
The results of the filtration depend highly upon what sorts of filters are being used. High-quality waterways filters will yield the best results. In this second stage, the membrane is used to filter the water and remove anything in it.
- The Post Filter Stage
The third stage of this process is the one which deals with things such as color, odor, and taste, etc. Carbon filters are used at this stage in particular to polish its taste.
The best RO system
Usually, these three stages are enough to produce the desired results. Some companies tend to market water purification filtration systems with 15 or 20 stages which are, more often than not, highly unnecessary. The best sort of RO system will be one that includes or has the option of expansions. These expansions allow for you to change up the RO system to filter out viruses or adjust pH or even add nutrients to the water. This is a far better option than RO systems with 20 stages just because it can be adjusted according to someone’s requirements.
Uses of RO
The most common usage od RO is to filter drinking water. RO began to be used in this particular way in the 1950’s when researchers from UCLA and University of Florida decided to try this method. On a larger scale, it began to be used in 1977 when Florida’s Cape Coral began to use it to purify drinking water.
Why use RO?
This method is great because it filters out 93 to 95% of dissolved salts, heavy metals and bacteria, etc. in the water supply, making your drinking water very clean. Asbestos, lead, mercury, and calcium in your drinking water can be filtered out with ease. Particles as small as 0.001 microns are trapped with the filter and microbial cysts are also removed. The only issues one can face are the wastage of water and the issue of chlorine not being filtered out. The latter can be fixed by attaching a carbon filter which helps solve this in no time. RO is the best water filtration and purification system for household or commercial use.
Reverse osmosis systems guarantee that the water being filtered is pure of impurities and healthy as well. It can be used in the household as well as for commercial and large scale usage, which is why RO systems and investment in them is a great option for everyone. Do a lot of thorough research and invest in an RO filtration system that suits your needs and requirements perfectly.
