Water is a basic resource that guarantees life to all living things on earth. That’s why access to clean water is essential for hygiene and sanitation. Unfortunately, many people are struggling to get access to clean, drinkable water every day.
Whether you’re a homeowner, a business owner, or a community leader, water treatment solutions can help you make sure that the water you and your loved ones are drinking is free from harmful contaminants. From traditional filtration systems to cutting-edge technologies, we’ll explore what happens during each treatment method.
Steps in water treatment
The Centers for Disease Control and Prevention (CDC) identify the different water treatment methods public drinking water systems use to provide safe drinking water for their local communities. Each community has a different water source, so its water treatment requirements may differ. The steps are as follows.
Coagulation is the first step in water treatment. It is a water treatment method that removes suspended particles in water, such as dirt, clay, and algae. This process destabilizes the particles so they can be more easily removed by sedimentation or filtration.
The process of coagulation involves adding a chemical coagulant, such as aluminum sulfate (alum) or ferric chloride, to the water. The coagulant reacts with the suspended particles, causing them to stick together and form larger particles called flocs. These flocs can be easily removed by sedimentation or filtration.
Flocculation is a water treatment process used in conjunction with coagulation. This process combines the flocs created by the coagulation process to form larger ones that can be more easily removed by sedimentation or filtration.
During flocculation, the water is slowly agitated typically using low-speed mixers to encourage the formation of larger flocs, thus allowing them to settle out more easily and quickly. This process can be done in various ways, such as with a series of mixers, a sedimentation basin, or a flocculation chamber.
The next step, sedimentation, is a water treatment process that separates and removes solid particles, such as dirt, clay, and algae, from water by allowing the particles to settle out naturally under the influence of gravity.
Sedimentation can be accomplished in various ways, such as with a sedimentation basin, a clarifier, or a settling tank. The water is typically allowed to flow into the sedimentation basin or tank and then sit for a while. During this time, the solid particles will settle to the bottom of the basin, while the clean water can flow over the top and out of the basin.
Following sedimentation is filtration, a water treatment process that uses a filter medium to physically remove suspended particles, such as dirt, clay, and algae, from water. There are several types of filtration methods:
Sand filters use a bed of sand to remove particles from water. Water is passed through the filter, and the particles are trapped in the sand.
Activated carbon filters use a bed of activated carbon to remove impurities from water. The activated carbon absorbs contaminants from the water, such as chlorine and organic compounds.
Reverse osmosis filters use a semipermeable membrane to remove impurities from water. The membrane only allows clean water to pass through, while contaminants are trapped on one side of the membrane. This is usually used to treat recycled water.
Ultrafiltration uses pressure or concentration gradients to force the thorough separation of particles, bacteria, and viruses from water through a semipermeable membrane with very small pores.
Disinfection is a water treatment method that involves the use of physical or chemical disinfectants to kill or deactivate harmful pathogenic microorganisms in water, such as bacteria, viruses, and parasites. It is a necessary step to ensure that the water we use is safe to drink and for other uses.
Several disinfection methods used in water treatment include the following:
Chlorination is the most common method of water disinfection. It involves the addition of chlorine to the water, which kills or deactivates harmful microorganisms.
Ultraviolet (UV) disinfection uses UV light to terminate pathogenic microorganisms in water. UV light penetrates the cells of these microorganisms and disrupts their DNA, making them unable to reproduce.
Ozone disinfection uses ozone (O3) gas to kill or eliminate harmful microorganisms in water. Ozone is a powerful oxidant that penetrates the cells of microorganisms and disrupts their metabolism.
Chlorine dioxide is a soluble chemical compound used in water disinfection. It is more effective than chlorine in deactivating chlorine-resistant pathogens.
The Importance of water treatment solutions
Clean drinking water is essential for every living organism here on earth, and water treatment solutions make it possible for people to gain access to clean and safe water. In addition, they play a critical role in protecting public health, preserving the environment, and supporting industrial and commercial activities.
Here are some compelling benefits of water treatment solutions that justify their importance:
Ensuring public health – They help remove harmful contaminants from water, such as bacteria, viruses, and chemicals that can cause waterborne illnesses and diseases. These solutions ensure that the water you drink and use is safe for consumption, and helps prevent the spread of diseases.
Environmental protection – They reduce the number of pollutants and waste in our water supply. These help protect our natural water sources and preserve the environment for future generations.
Industrial and commercial uses – Water treatment systems are also very useful in industrial and commercial services. For example, reverse osmosis is often used to purify water used in producing foods and beverages and manufacturing semiconductors and pharmaceuticals.
Cost effectiveness – Implementing these solutions can help you mitigate water-related expenses in the long run. For example, installing a water filtration system can save you money that you would have spent on bottled water, and eliminate the need to pay for expensive repairs of appliances that may have been damaged by hard water.
Addressing water scarcity – With the increasing population and industrialization, water scarcity is becoming an issue in many areas. These solutions help make more water available for consumption, and help reduce the strain on natural water sources.
Compliance to local laws – Many industries are required by government laws to meet certain water quality and safety standards. Water treatment systems help these industries comply with these regulations and avoid penalties.
The Bottom Line
Water treatment solutions are essential to ensuring that our water is safe, clean, and free of impurities. Various water treatment methods have been discovered and developed to eliminate contaminants that can cause health risks. Treatment methods such as coagulation, flocculation, sedimentation, filtration, and disinfection are often done hand in hand to guarantee access to clean, drinkable water.
