Purification of Drinking-water Supplies

by Stimulated Natural Attenuation Stimulated natural attenuation (SNA) is a process used to purify drinking-water supplies. This technique harnesses the natural ability of the environment to remove contaminants from water via a variety of biochemical, physical and transport processes. The contaminants are broken down into less harmful by-products, making the water safe for drinking. SNA is an effective, economical, and sustainable approach for purifying drinking-water, as it does not require costly capital investments or require the formation of hazardous waste streams. It also has the potential to reduce environmental impact, since the natural attenuation processes are already in place, and requires little additional energy or resources to activate. This process is widely applied in various areas of water quality management, including industries and municipal water systems, and is increasingly valuable in developing countries. SNA has proven to be cost-effective and reliable, and therefore, is an essential technology for ensuring safe drinking-water.
