摘要: The present invention provides a process to clean water filtration media in bed. includes applying granular cleaner the (120) and an activator (30). This causes chemical reaction between cleaner, resulting cleaning of media. residual activator, along with suspended dissolved contamination from media, are removed by rinsing (40).
