The Different Stages of Water Treatment
Written By : drinking water supply in dubai Water treatment is a critical process that ensures the provision of safe and clean drinking water to communities while also protecting the environment. It involves several stages to remove contaminants and impurities from raw water sources. Here are the typical stages of water treatment: 1. Coagulation and Flocculation: Coagulation: In this stage, chemicals called coagulants, such as aluminum sulfate or ferric chloride, are added to raw water. These chemicals neutralize the electrical charges of fine particles and colloids in the water, causing them to come together or coagulate. Flocculation: After coagulation, gentle mixing is applied to encourage the coagulated particles to form larger clumps called flocs. This process makes it easier to remove impurities in subsequent stages. 2. Sedimentation: In this stage, the water is allowed to sit undisturbed, allowing the heavy flocs to settle at the bottom due to gravity. This results in...
