PROCESS FOR IN-SITU CLEANING OF DRINKING WATER FILTRATION MEDIA
摘要
<p>The present invention provides a process to clean water filtration media in a filtration bed. The process includes applying a granular cleaner to the water filtration media (120) and applying an activator to the water filtration media (30). This causes a chemical reaction between the granular cleaner, activator and water filtration media resulting in the cleaning of the water filtration media. The residual granular cleaner and activator, along with suspended and dissolved contamination from the water filtration media, are removed by rinsing with water (40).</p>
