Water is essential to all life on earth, not just human life. Therefore, it is important for us to have access to safe, clean drinking water. Whereas South Africa boasts safe water treatment, not all water sources in the country are safe or clean, due to contamination that can easily occur naturally or through human activities. Because of this, there is a growing need for effective water purification processes.

Water purification is the removal of unneeded chemicals, biological contaminants, suspended solids and gasses from the water. In general, this technology aims to provide appropriate quality water for specific use.

At MANZI Water, our priority is to provide safe, clean, purified water for drinking. We do this by utilising an advanced, rigorous, six-stage water purification process designed to remove contaminants and deliver the highest quality product possible. The processes below are used by MANZI Water in our water purification process.

Sand Filtration

The initial step of our water purification process involves sand filtration. This process involves passing water through a single tank of different sands of varying grain sizes. The water flows from the largest to increasingly finer sands. Sand traps a vast amount of the particles and sediment thus removing them out of the water supply. This process ensures that the large impurities which make the water unclear and also clog the other filters in the system can be removed.

Element Filtration

The second stage of MANZI Water’s purification process is element removal. Here, water flows through the filter that captures the finer, suspended particles that could have made it through the sand filtration. The water first flows through a 5 micron filtering element, which removes undissolved solids as small as 5 microns (0.005mm). Thereafter, it flows through a 1 micron filtering element able to remove particles as small as 1 micron (0.001mm). In this process, the fine contaminants such as microscopic parasites, and some bacteria that most likely skipped the first phase of the sand filtration can be wiped out.

Reverse Osmosis

Reverse osmosis is able to remove dissolved ionized solids including heavy metals, salt, and other dangerous impurities. Water is forced through a semi-permeable membrane, which are filters only allowing water molecules to pass through, and the contaminants are left behind. This stage of the water purification process takes out between 95% to 99% of all dissolved solids from the water.

Carbon Filtration

The fourth stage of MANZI Water’s purification process involves carbon filtration. During this stage, water is passed through a tank filled with activated charcoal. The activated carbon effectively absorbs chlorine, pesticides, herbicides, and various other organic compounds from the water. This process not only improves the taste and odour of the water but also makes it significantly cleaner and safer for consumption.

UV Protection

In this step of the water purification process, water is exposed to UV light, which dismantles all harmful microbes, like bacteria, viruses and hormonal substances that survived during previous purification stages. This guarantees that the final water is safe and clean of micro-organisms able to cause disease.

Ozone Treatment

This is the final stage of MANZI Water’s purification process. At this stage, ozone (O3), a highly potent oxidizing agent, is introduced into the water. Ozone is effective in breaking down and removing any remaining organic substances, ensuring that any leftover taste, scent, or contaminants are completely eradicated. Furthermore, it is excellent at disinfecting the water, as it destroys bacteria, viruses, and other pathogens, enhancing water safety. Following its reaction, the ozone decomposes back into oxygen. This transformation not only prevents ozone-related by-products but also increases the dissolved oxygen content in the water, which is beneficial for its quality. The outcome of ozone treatment is water that is not only free from hazardous elements but also enriched with oxygen, making it exceptionally pure and safe for human consumption.

Bottom Line

As you have seen, MANZI Water’s purification process is rigorous and this ensures that the final product is 100% purified water. So, visit our website or any of the various outlets across South Africa to make your order of safe, clean, purified drinking water from MANZI Water.

In South Africa, water from the tap can generally be safe to drink, due to basic water treatment plants in the country.

However, ozone treatment is an excellent choice in water purification. The principle is adding an atom to oxygen molecules to form O₃. The O₃ is used for water purification as it has been proven to purify water well and add oxygen to it.

Ozone water treatment aims at treating all the water contaminants in a fast and efficient manner. This method of water treatment is environmentally friendly and does not affect aquatic life.

The Process of Ozone Water Treatment

The ozone water treatment process combines the manufacture of ozone gas and the application of this gas to the water that should be cleaned. The production of ozone gas is done by specialised equipment that creates ozone using the corona discharge process. The corona discharge takes place when high-voltage electricity passes through oxygen molecules resulting in the generation of ozone as the end result.

When the ozone is produced, it is poured into the water which needs to be cleaned. The ozone molecules readily attach to and annihilate micro-organisms, bacteria, viruses, and other pollutants in water. The ozone molecules act as oxidizing agents, which then eliminate contaminants. After that, they break down into oxygen molecules with no toxic residues or any by-product left behind.

Any unreacted ozone that is not consumed during the process returns to its original oxygen state in about a minute. The water is passed through treatment plants again to remove any remaining pollutants and solids before the water is discharged for use. Ozone water treatment can be applied to multiple water sources, such as domestic water, wastewater, and even swimming pool water.

Benefits of Ozone Water

There are many benefits that one receives when drinking ozone water, since it contains more dissolved oxygen and ozone molecules which give the drink a unique aroma and quality.

Improved Immune System

Drinking ozone water may strengthen the immune system, preventing infections and diseases, since the water is free from harmful contaminants.

Better Hydration

Ozone water is pleasant to drink due to its particular flavour and coolness. Because of this, you may end up consuming more water and reaping the many benefits of drinking water.

Enhancement of Oxygen Levels

Ozone is a highly reactive form of oxygen that readily combines with molecules. The catalytic effect of ozone significantly enhances the oxygen saturation level in water, which is crucial for maintaining biodiversity and human well-being.

Standard vs. Ozone Water

Both treated and ozone-treated waters are considered safe. However, ozone offers significant advantages. In regions like Johannesburg, where water quality can vary greatly, opting for ozone-treated water instils confidence in its safety. Not only is it safe, but it is also beneficial to one’s general well-being.

Conclusion

The shift to ozone water may at first seem insignificant, but in reality, it may make you feel significantly better and live a healthier life. Visit our website or any of the various outlets of MANZI Water in South Africa and get your ozone water today.

Staying hydrated is very important, but have you ever thought about the quality of water that you are drinking? While South Africa has safer tap water than many countries, it might still have small but deadly pollutants including viruses, bacteria, heavy metals, and chemicals. These pollutants have the potential to make you sick, from mild infections such as gastrointestinal disturbances and diarrhoea to life-threatening illnesses like cancer, organ damage, and neurological infections. So, how pure is your tap water? Let us look at some of the potential hazards of tap water, and explore why purified water from MANZI Water might be the better choice for optimal health.

Water Quality Standards in South Africa

The Department of Water and Sanitation is responsible for overseeing the nation’s water resources. This body established the national water quality standards, as outlined in the South African National Standards (SANS) 241:2015. This document specifies the permissible limits for different physical, chemical, and microbiological properties in drinking water. Moreover, through the Blue Drop Certification Programme, the Department of Water and Sanitation performs audits on water quality nationwide, motivating municipalities to excel in managing drinking water quality.

Common Tap Water Pollutants

South Africa generally has advanced treatment infrastructure for tap water. But the water can carry trace amounts of pollutants due to geographic differences and concerns with the treatment facility’s operations. Among the contaminants include the following:

Microbial pollutants

Inadequately managed sanitation, septic system leakage, or contaminated wells in rural areas where indigenous communities live can lead to the entry of bacteria such as E.coli, viruses such as hepatitis A, and parasites such as giardia. These can cause short-term issues like vomiting and diarrhoea or severe long-term health concerns.

Agricultural run-off

Pesticides and herbicides connected to farming may get into tap water, particularly in locations where agriculture is intensive. These may affect hormones, the nervous system, and potentially increase cancer risk.

Industrial contaminants

Chemicals such as arsenic, mercury, and other heavy metals can infiltrate water supplies due to faulty industrial waste management. Such pollutants can cause organ damage, neurological disorders, and some specific cancers.

By-products of disinfection

By-products of disinfection can chemically react with natural organic matter in the water to create disinfection by-products, like trihalomethanes. Prolonged exposure of human beings to these chemicals has an increased risk of developing cancers, especially bladder cancer.

Emerging pollutants

Trace amounts of pharmaceuticals, personal care items, and hormones might be detectable in some water supplies due to inadequate disposal or incomplete treatment removal. The health implications of low-level exposure to these pollutants, including hormone disruption and antibiotic resistance, are still under investigation.

Purified Water vs. Tap Water

Unlike tap water which may contain contaminants, purified water is treated to remove contaminants. Purification is the process of removing contaminants and other non-useful substances from tap water. Water may be purified using reverse osmosis or ozone treatment. Reverse osmosis involves the use of pressure to push water molecules through a semi-permeable membrane. This is critical due to the fact that dissolved solids, organic compounds, and other pollutants are completely eradicated and lead to purified and clean water.

Ozone treatment on the other hand involves using a powerful oxidant (ozone) to eliminate bacteria and viruses. The main reason why ozone is preferable to disinfectants like chlorine is that the use of ozone is less harmful to the environment.

South Africa faces a pressing challenge of water supply scarcity. While most citizens possess access to piped water, the nation grapples with the reality of limited water resources. The two main types of water supply in South Africa are surface water and groundwater. Surface water is collected from rivers, dams, and lakes, while groundwater is obtained from underground aquifers through boreholes.

Both types of water supply face challenges in South Africa, including drought, pollution, and ageing infrastructure. However, groundwater is often seen as a more reliable and sustainable option, especially in areas where surface water is scarce or polluted.

Current State

There are several issues related to the current state of South Africa’s water supply. One of the main concerns is the limited availability of water resources due to drought, climate change, and population growth. This has led to water scarcity in many parts of the country, particularly in the Cape Town area, where a severe drought in 2017-2018 prompted the city to implement strict water restrictions.

Additionally, the country’s ageing water infrastructure needs major upgrades and repairs to address leakages and losses. This has contributed to water shortages and poor water quality in some areas.

Another concern is the unequal distribution of water supply resources, with some regions having an overabundance of water while others face significant scarcity. This has resulted in conflicts over water rights and allocation, particularly between rural and urban communities.

Efforts have been made to address these challenges, including infrastructure investments and water conservation campaigns. However, there is still much work to be done to ensure that South Africa’s water supply is adequate, equitable, and sustainable for all its citizens.

In today’s world, where single-use plastics are a significant concern to the environment, many people are turning to reusable water bottles as a more sustainable option, but a common question that arises is whether refilling water bottles is safe.

The Concerns Surrounding Refilling Water Bottles

Bacterial Growth

Repeated use of plastic water bottles can lead to the growth of bacteria inside the bottle, especially if it is not cleaned regularly. Bacteria can thrive in moist environments, and tiny cracks or scratches in the plastic can provide breeding grounds for these organisms.

Chemical Leaching

Plastic water bottles are made from various types of plastic, some of which can leach chemicals into the water, especially if the bottle is exposed to heat or stored for long periods. The most common types of plastic used for water bottles are Polyethylene Terephthalate (PET) and Polycarbonate (PC).

Physical Damage

Reusing plastic water bottles can cause physical damage to the bottle, including scratches and cracks. These areas can be difficult to clean thoroughly and, if left unchecked, can harbour harmful bacteria.

Mould Growth

If the water bottle is not cleaned and dried properly, mould can grow inside it. This can cause respiratory problems if the mould is inhaled. It is important to clean and dry the bottle thoroughly to prevent mould growth before refilling water bottles.

Plastic Degradation

Repeated exposure to heat can cause plastic water bottles to break down and release harmful chemicals. This can occur if the bottles are left in a hot car or if they are heated in a microwave. It is important to avoid exposing plastic bottles to high temperatures to prevent this type of chemical contamination.

Long-Term Reuse

While plastic bottles can be reused, many are designed for single use and may degrade over time. Signs of wear and tear, such as discolouration, scratches, or cracks, can indicate that the bottle is nearing the end of its useful life. It is important to replace plastic bottles regularly to ensure they remain safe for reuse.

Proper Maintenance and Hygiene Practices

Although these concerns are valid, they can be mitigated by following proper maintenance and hygiene practices.

Cleaning and Sterilisation

Regular cleaning and sterilisation of your refillable water bottles are crucial to avoid bacterial contamination. Wash the bottle thoroughly with warm, soapy water after each use, and rinse it well. It is also advisable to use a bottle brush to reach all corners and crevices of the bottle. For an extra level of cleanliness, you can also sterilise the bottle using hot water or a sterilising solution.

Avoiding High Temperatures

To minimise the risk of chemical leaching, avoid exposing your water bottle to high temperatures. Do not leave it in a hot car or use it for hot beverages, as the heat may accelerate the release of chemicals from the plastic.

Regular Replacement

Keep in mind that refillable water bottles eventually wear out and should be replaced periodically. Inspect your bottle regularly for cracks, scratches, or signs of deterioration. When you notice any damage, it is time to invest in a new bottle to ensure your safety and well-being.

Choose BPA-Free Bottles

As research has established a connection between BPA exposure and various health issues, including cancer, obesity, and reproductive disorders, it is important to choose bottles that explicitly state they are BPA-free when purchasing a reusable water bottle. These bottles are made with materials that are less likely to leach harmful chemicals.

Conclusion
