Reverse Osmosis systems, also called RO systems and RO water purifiers, can remove common contaminants with known human toxicity. But how to tell if your water may be contaminated and how well do RO systems perform in removing known toxins and Emerging Substances of Concern (ESOCs)? Let’s find out!
Do I Need a Reverse Osmosis System?
South Africa has a reputation for high quality municipal water and publishes their test results annually. However, the published annual results only show results from 12 testing locations and the Department of Water & Sanitation’s IRIS system reveals that this reputation may be unfounded. Water quality fluctuates significantly on a day-to-day basis with many local municipalities routinely exceeding a number of different Minimum Risk Parameters for toxins stipulated in SANS 241-2 2015. Some municipalities don’t provide measurements at all. A Reverse Osmosis System will help ensure your tap water is as toxin-free as possible.

Lead
Corroded pipes aren’t only a source of copper and cadmium poisoning. Metallic or salty tasting water may be a result of lead leaching in from non-compliant plumbing. Lead poisoning is particularly dangerous in children, affecting brain development and multiple other body systems. Lead, like other heavy metal toxins, is cumulative and is not eliminated from the body without special medicines.
Can a Reverse Osmosis System Remove It? Yes.
Sodium
Sodium is essential for the healthy functioning of the body but excessive amounts are associated with heart disease. Excessive sodium levels are detectable by a salty taste.
Can a Reverse Osmosis System Remove It? Yes.
Sulphides
Rotten egg odour! Sulphides can enter into waterways from geological sources and can cause scale buildup in plumbing systems (apparent in drains) and hot water kettles. These substances can have a laxative effect, especially concerning among infants.
Can a Reverse Osmosis System Remove It? Yes.
Reverse osmosis systems can remove the toxins which enter municipal water from ageing infrastructure and non-compliant plumbing.
Fluoride
White or brown stains on teeth may be evidence of excessive levels of fluoride compounds in the water. Fluoride has been scientifically proven to reduce cavities and promote strong, healthy teeth but so long as you’re using a fluoridated toothpaste you’re getting enough already. Excessive levels may enter waterways from groundwater and springs resulting in unsightly dental stains.
Can a Reverse Osmosis System Remove It? Yes.
Cadmium
Cadmium enters into waterways from mine and industrial effluent but can also result from deteriorating galvanized plumbing. Cadmium poisoning from water sources can cause nausea, vomiting, stomach cramps, diarrhea, and kidney damage. Water with a ‘fishy’ odour may be contaminated with cadmium.
Can a Reverse Osmosis System Remove It? Yes.
Chlorides
Most are familiar with the distinctive scent, taste, and milky white cloudiness associated with chlorinated water. Chlorine and chlorides are used to disinfect and purify water for safe drinking. However, it may also react with other contaminants and produce harmful byproducts such as trihalomethanes. Trihalomethanes are associated with higher risk of bladder, bowel and kidney cancer. Additionally, high levels of chlorides can interact with sodium pathways, causing hypertension.
Can a Reverse Osmosis System Remove It? Yes.
Copper
A metallic taste, or a blue or green tint could be evidence of oxidised copper in your drinking water. Though copper is considered a micronutrient, required by the body for proper functioning, too much copper can be harmful. It is associated with nausea, diarrhea, liver, and kidney damage.
Can a Reverse Osmosis System Remove It? Yes.
Reverse osmosis systems can ensure your water is always clear and free from nasty tastes and smells.
Invisible Toxins & Reverse Osmosis Systems
Many of the toxins tested for at a municipal level are not detectable by taste, sight, or smell. Additionally, there are a plethora of Emerging Substances of Concern (ESOCs) with known and unknown health consequences that are not covered by SANS 241-2 2015. Endocrine disrupting microplastics and pharmaceuticals, non-biodegradable carcinogens (“forever chemicals”) like polyfluoroalkyl substances (PFASs), and nitrates from chemical fertilizers are not detectable without laboratory equipment. Thankfully, reverse osmosis systems are effective at removing these contaminants as well.
Are Reverse Osmosis Systems the Solution?
Reverse osmosis systems are able to remove a vast majority of contaminants and potential toxins. They’re an extremely effective way to achieve total peace of mind when it comes to water safety. Professional grade RO systems installed by WUS experts are the effortless way to guarantee crystal clear water is available through your building.
