The primary resource that ensures the survival of all life on Earth is water. Although having access to water purification, sanitation, and hygiene is a fundamental human right, billions of people everyday struggle to get even the most basic amenities.
Water purification completely determines how safe it is to consume. To verify that water fulfils the regulations set out by the government to provide safe drinking water, water must be tested. To guarantee that water is adequately cleansed and benefits the community, it is essential to comply with these criteria. An important component of a community’s health and safety is access to clean drinking water. Understanding the five phases of water treatment is so crucial.
Here we are going to discuss about the steps involved in the water purification system. So, let’s get started….
Water treatment: Water treatment ensures access to clean water and prevents rivers and seas from being contaminated. Water treatment is a procedure that combines many operations (physical, chemical, physicochemical, and biological), with the objective of reducing or eliminating contaminants or undesirable qualities in water.
Obtaining water with the proper characteristics for the intended application is the goal of this process. This is why the characteristics of the supplied water and its intended use affect how the water is treated. Due to a lack of drinking water and the expanding requirements of the world’s population, water treatment is becoming more and more important. Only 2.5% of the planet’s total water reserves are freshwater, and only 0.4% of this is suitable for human use.
Here are few steps employed in the water purification treatment:
Screening:
Water enters a water treatment facility through a screening after coming from rivers, lakes, or the ground. Large natural pollutants are kept out of the water by this filtering. These can be anything, including fish and timber. With groundwater sources, screening is not as important since the act of extracting the water from the ground serves as a natural screening mechanism.
Coagulation:
Workers at the treatment facility add chemicals to the water during the coagulation stage, which causes particles to develop in the water. The most used coagulants are ferric and aluminium sulphates. They are incorporated into the water in a turbulent area. These compounds produce sticky particles that are referred to as floc. Floc draws dirt particles to itself.
Sedimentation:
Sediment is the term used to describe these floc and soil fragments that are settling to the bottom of the storage tank. During this procedure, both the water and the sediment in the water move into a sedimentation basin. Water flow velocity is decreased in sedimentation tanks so that suspended materials can settle more easily. Again, the heavier floc particles drop to the basin’s bottom and stay there until they are removed.
Filtration:
After that, a layer of sand and gravel is passed over the cleaned water (occasionally charcoal as well). During this procedure, the sand layer is approximately 2.5 feet deep and the gravel layer is normally around 1 foot deep.
Gravity filters are frequently used to eliminate floc, while pressure filters are frequently used to maintain hydraulic head. These filtering systems get rid of any extra particles, including turbidity and algae, that remain after the sedimentation process. The water then enters a sealed tank after this.
Disinfection:
Chlorine and other disinfection agents are used in this tank to eliminate any germs and pathogens present. As a result, the water is kept clean until it is given to the neighborhood. Pipes are used to transport it to residences and commercial buildings. It stays in the tank until then to continue being cleansed.
It should be noted that disinfection may be the only level of treatment your water needs if your major source of water is groundwater. Your community’s access to clean drinking water and assurance that the water is safe for your health are both made possible by these five processes.
Conclusion:
Potable water is a precious yet limited resource. Only 0.4% of the water on the globe is thought to be suitable for human consumption. Investments in water purification are crucial to guarantee that everyone gets access to this key resource. The major goal of purification is to get rid of any potentially harmful elements from the water, such as germs, viruses, and heavy metals like chromium, lead, and zinc. Essentially, it seeks to eliminate any threat to the health.
