Frequently asked questions about reverse osmosis and water purifiers

In reverse osmosis, water (the solvent) moves from an area of higher solute concentration to an area of lower concentration. Water is subjected to higher pressure than the feedwater, and filtration occurs due to the pressure difference through which water is forced through the microscopic pores of the osmotic membrane, while larger particles are retained.
The reverse osmosis purification system consists of sediment filters, activated carbon filters, and an osmotic membrane.
In a reverse osmosis system, it is advisable to change the activated carbon filters every six months, while the osmotic membrane can be replaced every three to four years.
Modern reverse osmosis purification systems are equipped with a bypass valve that reintroduces some of the water during the osmosis process to achieve the best mineral salt balance in the water.
Water treated with a reverse osmosis purification system is safe, light, pleasant, and hygienically perfect. Furthermore, some of the minerals that would be removed by the osmotic membrane are reintroduced through the bypass valve.
