What is Reverse Osmosis?

Reverse Osmosis, commonly abbreviated to RO, is a water treatment method traditionally known for removing salt from seawater, it is also used to purify drinking water by forcing untreated water molecules through a semipermeable membrane. The membrane has a tight pore structure that effectively removes up to 99% of all contaminants and impurities such as total dissolved solids, chemicals, bacteria and viruses from drinking water. Anti-microbial filters used in Reverse Osmosis also help to remove unwanted odours, colours and tastes from water. The result is pure, clean, drinking water.


How does a Reverse Osmosis System work?

Although Reverse Osmosis seems like a complex system it is really a simple and straightforward water filtration process. Of all methods to purify water for domestic use, the process of using reverse osmosis is the most advanced, economical and effective.

RO is a process in which dissolved inorganic solids are removed from the water. This is accomplished by household water pressure pushing the tap water through a semipermeable membrane, the membrane has the astounding quality of attracting water molecules and repelling dissolved impurities, even those smaller than the water molecules themselves. The membrane, which is about as thick as cellophane, allows only the water to pass through, not the impurities or contaminates.

What does a Reverse Osmosis System remove?

Reverse Osmosis successfully removes dissolved minerals and metals such as; Fluoride, Sodium, Calcium, Magnesium, Potassium, Iron, Manganese, Aluminium, Ammonium, Copper, Nickel, Zinc, Strontium, Cadmium, Silver, Mercury, Barium, Chromium, Lead, Chloride, Bicarbonate, Nitrate, Fluoride, Silicate, Phosphate, Chromate, Cyanide, Sulfate, Thiosulfate, Ferrocyanide, Bromide, Borate, Arsenic, Selenium, Trihalomethanes.

How often do I need to change the filters on my Reverse Osmosis System?

Once a year. Depending on the quality of your water, some filters may need to be changed every six month. Renewell Water will notify you when it is time to replace your filters.
