5 Common Water Treatment Problems and How to Effectively Solve Them

5 Common Water Treatment Problems and How to Effectively Solve Them

Water is a vital resource, and its treatment is essential to ensuring its safety, cleanliness, and quality. Whether for drinking, irrigation, or industrial use, untreated water can often contain various impurities and contaminants. At H2O Warehouse, we understand the complexities of water treatment and offer a range of tailored solutions to tackle the most common issues. Below are the five most prevalent water treatment problems and how to solve them in detail.

1. High Levels of Hardness

Problem: Hard water is one of the most common issues in water treatment. It occurs when water contains elevated levels of minerals, particularly calcium and magnesium. These minerals can form deposits known as scale that accumulate in pipes, water heaters, and appliances. Over time, these deposits can reduce the efficiency of water systems, increase energy costs, and shorten the lifespan of household appliances. Hard water can also affect the taste and feel of water, leaving it unpleasant for drinking and bathing.

Solution:
To address hard water, the most effective solution is installing a water softening system. These systems use specific media that can bind with calcium and magnesium ions, removing them from the water supply. Some of the best media options for water softening include:

  • Calcite Media: Calcite is an effective way to neutralise acidic water and help prevent scale formation. It can be added to your filtration system to maintain optimal water quality. For product options click here:

  • Siliphos Media: Siliphos is a unique blend of phosphate-based compounds that help prevent scale build-up without altering the water’s mineral composition. This solution is excellent for protecting appliances and pipes from scaling while still keeping the beneficial minerals in the water. For product options click here:

  • Ion Exchange Softening: A traditional method involving resin beads that exchange sodium ions for calcium and magnesium ions in the water. The result is softer water with a reduced risk of scale build-up. For product options click here:

By incorporating any of these solutions into your water treatment system, you can prevent the negative effects of hard water and maintain the efficiency of your water systems.

2. Contaminants in the Water

Problem: Contaminants such as bacteria, viruses, heavy metals, chlorine, and agricultural runoff are common in both municipal and private water supplies, particularly in wells or boreholes. These contaminants pose significant health risks, from gastrointestinal illnesses to long-term diseases caused by exposure to heavy metals like lead or arsenic.

Solution:
To ensure your water is free of harmful contaminants, a multi-stage filtration system is often required, including:

  • Reverse Osmosis (RO) Systems: Reverse osmosis is one of the most effective methods for removing a wide range of contaminants, including bacteria, viruses, heavy metals, salts, and chlorine. RO systems force water through a semipermeable membrane that filters out contaminants while leaving behind pure water. This system is especially effective for improving the quality of drinking water.  

  • Ultrafiltration (UF) Systems: Ultrafiltration is similar to reverse osmosis but uses larger pores in the membrane. It can remove particles, bacteria, and some viruses from water, making it suitable for a variety of applications, including drinking water and industrial use.

  • Activated Carbon Filters: Activated carbon is ideal for removing chlorine, chloramines, organic compounds, and some chemicals that can affect both the taste and safety of water. This type of filtration is often used in conjunction with other systems, such as RO or UF, to ensure comprehensive purification. 

  • UV Sterilisation: Ultraviolet (UV) sterilisation is an effective method to disinfect water by killing bacteria, viruses, and other pathogens without the use of chemicals. UV sterilisation can be used as a final step in a multi-stage treatment process to ensure your water is microbiologically safe. 

Investing in a combination of these systems provides a comprehensive solution to ensure clean, safe, and contaminant-free water.

3. Unpleasant Odours and Tastes

Problem: Water can develop unpleasant odours or tastes due to chlorine, sulphur, organic matter, or chemical pollutants. This is especially common in well or borehole water, which can naturally contain higher levels of sulphur, hydrogen sulfide, and organic compounds, leading to a "rotten egg" smell. Chlorine, often used to disinfect municipal water, can also cause a harsh chemical taste.

Solution:
To effectively combat these issues, consider the following filtration methods:

  • Activated Carbon Filters: Activated carbon is one of the most effective ways to remove chlorine, chloramines, organic compounds, and some volatile chemicals that contribute to unpleasant tastes and odours. It works by adsorbing contaminants onto the carbon surface, improving both the smell and taste of the water.

  • Catalytic Carbon Filters: Unlike regular activated carbon, catalytic carbon is specially treated to enhance its ability to remove chloramines, which are commonly used in municipal water treatment. These filters are ideal for removing the chemical taste and odour left by chlorine-based disinfectants.

  • Ozone Treatment: Ozone is a powerful oxidant that can destroy the microorganisms and organic compounds responsible for unpleasant odours and tastes. Ozone treatment works by breaking down chemicals and organic material, effectively improving water quality without the use of chemicals.

  • Aeration: Aeration systems can help eliminate gases like hydrogen sulphide, which causes the distinctive rotten egg smell. By introducing air into the water, these systems break down the dissolved gases and expel them into the atmosphere.

Incorporating these filtration systems into your water treatment setup will ensure that your water remains free of unwanted smells and tastes, providing a more enjoyable and healthier drinking experience.

4. Iron and Manganese Staining

Problem: Iron and manganese are naturally occurring minerals often found in well water or groundwater. These metals can cause staining on sinks, bathtubs, toilets, and laundry, leaving reddish-brown or black marks that are difficult to remove. The presence of these metals in water can also cause an unpleasant metallic taste and make your water less aesthetically appealing.

Solution:
The most effective way to address iron and manganese issues in your water is through dedicated filtration systems:

  • Iron Removal Filters: These filters use a combination of media such as greensand or birm, which oxidises iron and manganese, converting them into solid particles that can be filtered out. The filtered water is clear and free from staining, improving both its aesthetic appearance and taste. 

  • Oxidation-Reduction Filtration (ORF): Oxidation-reduction filters work by adding an oxidising agent, such as chlorine or air, to convert dissolved iron and manganese into solid particles that can be filtered out. These systems are highly effective in treating high concentrations of iron and manganese.

  • Air Injection Systems: These systems introduce oxygen into the water, causing iron and manganese to oxidise into solid particles, which are then removed by a filtration medium. Air injection systems are effective for groundwater sources with higher levels of iron and manganese.

These filtration solutions will not only remove the staining metals but will also improve the overall quality of your water.

5. pH Imbalances

Problem: The pH level of water plays a critical role in its quality. Water that is too acidic (low pH) can corrode pipes and appliances, while water that is too alkaline (high pH) can cause scaling and reduce the effectiveness of water treatment systems. A pH imbalance can also affect the taste of the water, making it either too sour or too bitter.

Solution:
Correcting the pH balance of water involves the use of specific media and treatment methods:

  • Calcite Media: Calcite is a naturally occurring form of calcium carbonate, which is used to raise the pH of acidic water. It dissolves into the water, neutralising the acidity and stabilising the pH to a more neutral level (around 7).

  • Soda Ash Feeders: Soda ash is commonly used to raise the pH of water. When introduced to acidic water, it reacts with the acids and raises the pH to a safe and optimal level.

  • pH Adjusters: For highly alkaline water, specific pH-lowering chemicals, such as food-grade phosphoric acid, can be used to adjust the pH level.

Proper pH balancing ensures your water is not only safe for consumption but also protects your plumbing and appliances from damage.
