Minerals are naturally present in water, whether it comes from a borehole, a river, or treated municipal pipes. These minerals come from the soil and rocks that water passes through underground. The most common ones include calcium, magnesium, sodium, iron, and manganese. While some minerals are beneficial, others cause problems when present in high amounts.
Calcium and magnesium are essential for bone health and help the body function properly. However, in water, they cause hardness, which leads to scale buildup on taps, kettles, and shower heads. Hard water also makes soap less effective and can irritate the skin. Magnesium and calcium contribute to a chalky taste that many Nigerians notice in borehole water.
Iron and manganese are another challenge. In small amounts, they are harmless. In high amounts, they leave yellow or reddish stains on buckets, tiles, and bathroom fixtures. They also create a metallic taste and unpleasant smell. These minerals are extremely common in Nigerian boreholes, especially in areas with iron-rich soil.
There are also dissolved solids like sulfates, chlorides, and nitrates. While some are harmless, others become dangerous at higher concentrations and can affect organs over time.
It is important to understand that minerals in water are not the body’s primary source of nutrients. Almost all essential minerals come from food, not water. Even if a purifier removes certain minerals, your diet still provides far more than water ever could. What matters most is removing the harmful minerals and contaminants that affect health and water quality. This is where RO systems become valuable, because they target the unwanted minerals that create stains, odors, and long-term health risks.
pH is a measure of how acidic or alkaline water is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. Anything below 7 is acidic, and anything above 7 is alkaline. Many people hear about pH in conversations about “alkaline water,” skin care, or health routines. But the truth is that pH is often misunderstood.
Natural water sources rarely sit at a perfect pH of 7. Rainwater is slightly acidic. Borehole water tends to be alkaline because it absorbs minerals from the soil. Tap water can vary depending on how it is treated. Chlorine, which is added to municipal supply, can change the pH slightly.
When water passes through an RO membrane, many dissolved solids are removed. This naturally lowers the pH slightly, usually resulting in water that sits between 6.5 and 7.2. This is still within safe drinking limits according to global health standards. The slight change in pH does not make the water harmful or dangerous. In fact, many common beverages including tea, soft drinks, fruit juices, and even bottled water brands have a lower pH than RO water.
The human body regulates its internal pH very tightly. The moment water is consumed, the stomach’s acid neutralizes whatever pH it carries. A glass of water cannot disturb the body’s balance because the body adjusts instantly.
Some households prefer slightly alkaline water for taste. In such cases, post-carbon filters or mineral cartridges can be added to RO systems. These add back small amounts of calcium or magnesium for taste, not for health necessity.
In general, the pH of RO water is nothing to worry about. It falls within safe consumption range and is far less acidic than many everyday drinks. What matters is that the water is clean, free from chlorine, and not contaminated by heavy metals or bacteria.
Reverse Osmosis is one of the most effective purification methods in the world. It works by forcing water through a semi-permeable membrane that traps impurities at the molecular level. This membrane has extremely tiny pores that allow only water molecules to pass through while blocking minerals, salts, chemicals, heavy metals, bacteria, and even viruses.
Before water reaches the membrane, it passes through pre-filters that remove sediments, chlorine, and larger particles. After the membrane, water often flows through a post-carbon filter for improved taste. Some systems also include UV disinfection for added protection.
RO is particularly useful in homes that rely on borehole or tanker water. These sources often contain dissolved metals like iron and manganese, which regular filters cannot remove. RO membranes are designed to remove these metals completely. The system also eliminates harmful substances like lead, arsenic, nitrates, and fluoride when present at unsafe levels.
RO does reduce mineral content, but the reduction mainly targets harmful or excessive minerals. Beneficial minerals in water are often present in very small amounts. As mentioned earlier, the majority of your dietary minerals come from food, not water. This is why RO water is still safe, healthy, and preferred in many parts of the world.
RO also improves taste. Water becomes cleaner, lighter, and more refreshing. It removes the metallic taste from borehole water and the chlorine smell commonly associated with tap water. For many Nigerian homes, RO becomes a long-term solution because it works reliably regardless of water source changes.
One of the most common myths is that RO removes too many minerals and leaves water “empty.” This misunderstanding comes from the belief that drinking water should be the main source of minerals. In reality, food provides up to 95 percent of the minerals the body needs. Water contributes only a small fraction.
RO removes minerals, but the minerals it removes are mostly the ones that cause problems. For example:
Removing these minerals actually protects the body. What remains is water that is cleaner, softer, and safer.
Studies show that people who drink RO water are not at risk of mineral deficiency. Minerals from food such as vegetables, fruits, beans, fish, meat, and dairy provide more than the body requires. In fact, many nutritionists explain that relying on water for minerals is not realistic.
Some RO systems add a small mineral cartridge at the final stage. This is not meant to provide nutrition but to improve taste. People often prefer the slightly balanced taste of mineralized water, especially if they previously drank borehole water rich in calcium or magnesium.
The argument that RO removes “too many minerals” does not match scientific evidence or everyday reality. The goal of water purification is safety, not nutrition. Clean water is far more important than mineral-rich but contaminated water. RO delivers that safety by ensuring every drop is free from harmful substances.
RO water provides many benefits that go beyond taste. It reduces health risks linked to contaminated water, especially in homes that rely on boreholes or tanker supply.
First, RO eliminates harmful microorganisms. While UF or UV can help, only RO physically blocks viruses and protozoa. This reduces the chances of waterborne diseases such as typhoid, cholera, and diarrhea.
Second, RO removes heavy metals. Many Nigerian soils contain iron, manganese, and sometimes lead. These are dangerous when consumed over time. RO membranes trap these metals and protect the household from long-term exposure.
Third, RO improves food safety. Cooking with RO water ensures contaminants do not enter soups, rice, baby food, or drinks. Many families notice smoother tea and clearer rice when RO water is used.
Fourth, RO improves skin and hair health. Hard water causes dryness and irritation. Soft, clean water feels better on the skin and reduces body odor caused by mineral reactions.
Finally, RO water reduces dependency on sachet or bottled water. This saves households money and reduces plastic waste. It also ensures consistent quality since sachet water varies widely and sometimes fails safety tests.
RO is not needed in every home. It depends on the water source. RO is necessary when water has:
These conditions are very common in borehole-dependent homes.
RO may not be necessary when:
In these cases, UV or activated carbon filters are enough.
However, many Nigerian homes switch between borehole, tanker, and tap supply. Because of this inconsistency, RO is often the safest long-term choice.
Some claims say RO water is “too acidic.” This is incorrect. RO water usually has a pH close to neutral. Slight drops in pH come from the removal of minerals, not harmful acidity.
The stomach quickly neutralizes the pH of anything you drink. Your digestive system cannot be affected by the pH of water. Many everyday drinks such as soft drinks, juices, tea, and coffee have pH levels lower than RO water.
If someone prefers slightly alkaline water for taste, mineral cartridges or alkaline filters can be added. These do not affect safety, only flavor preference.
