EFFECTS OF MEDIA, BACKWASH AND TEMPERATURE ON FULL-SCALE BIOLOGICAL FILTRATION

During ozonation, the amount of biodegradable organic matter (BOM) in natural waters increases. The presence of BOM is undesirable because it may result in biological instability of the drinking water and bacterial regrowth in the distribution system. This research investigated the sensitivity of BOM removal to operational parameters such as temperature, media type, and backwash conditions.
