  • PROCESS FOR IN-SITU CLEANING OF DRINKING WATER FILTRATION MEDIA
    Publication number: 20120040821
    Abstract: 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 and applying an activator to the water filtration media. 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.
    Type: Application

  • Process for in-site cleaning of drinking water filtration media
    Publication number: 20060043028
    Abstract: The present invention provides a process to clean said water filtration media in a filtration bed. The process includes applying a granular cleaner to the water filtration media and applying a catalyst to the water filtration media. This causes a chemical reaction between the granular cleaner, catalyst and water filtration media resulting in the cleaning of the water filtration media. The residue granular cleaner and catalyst, along with suspended and dissolved contamination from the water filtration media, are rinsed by the application of water.
