Water is an essential part of the human body, and the planet Earth as well. In today’s world, drinking water has become one of the most valuable liquids, if not the most valuable one. The reason to this is that there is not much of raw water that can still be used in nutrition, because most of it is polluted. However, there is a solution to this. There is a smart way of water filtering and it is called reverse osmosis. Take a look at the following few lines and read more about the reverse osmosis filtering systems, what they are, how they work, etc.

What is It?

Reverse osmosis (RO) is a technology of water purification which uses a selectively permeable membrane that allows molecules or ions to pass through it by diffusion, thus purifying the water and making it potable, clean and safe to drink. It assumes the application of an external pressure to reverse the natural flow of a pure solvent, such as water. Thus, separation efficiency in the reverse osmosis process depends on water pressure, solute concentration and water flux rate.

Parts of the System

The main components of the system are the following: (1) cold water line valve; (2) pre-filters; (3) reverse osmosis membrane (which is the heart of the system and where everything happens); (4) post filters; (5) automatic shut off valve (SOV); (6) check valve; (7) flow restrictor; (8) storage tank; (9) faucet, and a (10) drain line. However, there are some other factors which influence the process, such as the incoming water pressure, water temperature, as well as the type and quantity of dissolved solids in tap water, and the quality of filters and membranes used in the RO filter system.

How Does This Filter System Work

In a recent conversation with reputed suppliers of reverse osmosis filter systems, I learned that reverse osmosis is not a new water filtration system – it has been used for a long time for desalinating sea water into potable water (removing salt from sea water). The process starts when tap water is put in the system. The selectively permeable membrane or semi-permeable membrane (which is as thick as cellophane) filters impurities – such as pyrogens, bacteria, viruses, hydrocarbons, pesticides, turbidity, radioactive contaminants, chlorine, colloidal matter, detergents, dissolved solids, industrial wastes, etc. – and allows only pure water to pass through into the storage tank.

Advantages

RO filter systems improve the taste, odour and appearance of water, making it safe and good for use. This purification process is highly effective and will remove the aforementioned impurities at once. It does not consume energy, it is very convenient, it flushes away pollutants, without collecting them. RO filter systems are easily installed, both over sink and under sink, and it takes little effort, kept clean and they have a low production cost – giving you water of guaranteed quality for little money. Moreover, RO systems are not only used for water purification, but for waste water, as well in industries such as food production, hydrogen production, for reef aquariums etc.
