Different Stages

Stage 1
The first stage of the reverse osmosis water purification process is the sediment filter. In South Africa we have a fair amount of sediment such as dirt, rust, sand, silt and sediment in our water that can affect the taste and appearance of your water. The sediment filter removes all these floating impurities.

Stage 2
The second stage of the reverse osmosis water purification process is a carbon filter. Despite having relatively clean water compared to the rest of the world, contaminants such as chlorine, chloramine and other materials that cause bad taste and odors are present. The carbon filter removes these invisible impurities.

Stage 3 
The third stage of the purification process is the post carbon filter. The post carbon filter provides greater reduction of chlorine and chloramines.

These are called pre-filters because they are in front of the reverse osmosis membrane in the water purification process.

Stage 4
The fourth stage of the reverse osmosis water purification process is the RO Membrane. The semi-permeable membrane is 1/10,000 of a micron. The membrane will effectively reduce TDS (total dissolved solids) and removes a wide range of hard water contaminants such as Lead, Arsenic, Percolate, Radium, Copper, Barium, Chromium, Mercury, Sodium, Cadmium, Fluoride, Nitrite, Nitrate and Selenium. The reverse osmosis membrane removes over 99.95% parasite cysts

Stage 5
The final stage of the reverse osmosis water purification process is the Granular Activated Carbon (GAC) filter. The post-filter or final filter is the second activated carbon filter that polishes the water to crystal clarity. The result is the cleanest drinking water in South Africa with 99.95% less contaminants than water.
